Abstract:In the present research it is reported the synthesis and characterization of Poly (arylene ether ketone) (PAEK)-cadmium sulfide nanocomposites prepared using carboxylic-functionalized poly (arylene ether ketone) (PCA-PAEK) as the ligand in DMF solutions from Cd(Ac)2 and thiourea. The resulting CdS/PCA-PAEK nanocomposites were characterized by fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, UV-visible spectroscopy, photoluminescence spectroscopy, confirming the formation of CdS QDs with small particle size with structure. The results of photoluminescence measurement showed that the nanocomposite exhibited distinct luminescence properties. Furthermore, the effects of reaction time, CdS/PCA-PAEK ratio and Cd2+/thiourea ratio on the photoluminescence of CdS QDs were also investigated. Thus, a novel simple route was successfully developed for synthesizing nanohybrids based on quantum dots and high performance polymers with incorporated carboxylic moiety.

	Abstract:Poly(3-methacrylamido phenylboronic acid) (PMAPBA) homopolymer and poly(ethylene glycol)-b-poly(2-acryloxyethyl-galactose) (PEG-b-PAEG) glycopolymer were prepared successfully by reversible addition fragmentation chain transfer polymerization (RAFT) and atom transfer radical polymerization (ATRP), respectively. The formation of boronate crosslinked micelles based on the complexation of PMAPBA and PEG-b-PAEG were confirmed by dynamic light scattering (DLS), thermal analysis, and Alizarin red S (ARS) based colorimetric and fluorescence assay. The micelles showed significant pH, salt, and glucose sensitivity. At pH 5.0 and 6.0, the aggregation and precipitation of the micelles was observed. The particle size increased significantly as pH increased from 7 to 11. Due to shielding of the negatively charged phenylboronic acid groups, the aggregation of the boronate crosslinked micelles were found with increase of the salt concentration. Additionally, the glucose-responsive behavior of the micelles was dependent on the pH value. The sensitivity of the micelles to glucose was stronger at higher pH values.

	Abstract:Three novel soluble alternating conjugated copolymers PT-TZN, PF-TZN, and PBDT-TZN, comprised of thiophene, fluorene, benzo[1,2-b:4,5-b']dithiophene and thiophene derivatives with 3-nitro-1,2,4-triazole side chains, were synthesized via the palladium-catalyzed Suzuki coupling reaction and Stille coupling reaction. The effects of 3-nitro-1,2,4-triazole on the thermal, photophysical, electrochemical and photovoltaic properties were investigated. The introduction of the 3-nitro-1,2,4- triazole side chains benefits to lowering the bandgaps of the polymers. The bulk-heterojunction polymer solar cells were fabricated based on the blend of the as-synthesized polymers and the fullerene acceptor [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM). The maximum power conversion efficiency (PCE = 1.13%) was obtained with PBDT-TZN as the electron donor under the illumination of AM 1.5, 100 mW cm-2. The study results indicate that low bandgap derived from too strong electron-withdrawing groups does not always benefit to the PCEs of PSCs.

	Abstract:A series of poly(NIPAAm-co-GMA-Dex) hydrogels were synthesized from glycidyl methacrylate-derivatized dextran (GMA-Dex) and N-isopropylacrylamide (NIPAAm) in aqueous solution. The swelling properties, cell culture and detachment behaviors of these hydrogels were investigated. It has found that poly(NIPAAm-co-GMA-Dex) hydrogels are not only sensitive to temperature in deionized water and Dulbecco’s modified eagle medium (DMEM) (10%FBS), but also exhibit good biocompatibility. In addition, L929 cells were found to detach from the hydrogel surface naturally without affecting the function of L929 by controlling environmental temperature.

	Abstract:The amphiphilic block copolymer polystyrene-b-poly(N,N-diethylacrylamide-co-N,N-dimethyl-acrylamide) was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N,N-diethylacrylamide (DEA) and N,N-dimethylacrylamide (DMA) using polystyrene as macro-RAFT agent. Polymeric micelles were prepared by dialysis of the block copolymer solution in THF against aqueous media. The polymeric micelles PM73 based on block copolymer P73, which was prepared with molar ratio DEA/DMA/PSt CTA/AIBN = 700:300:10:1, exhibited a lower critical solution temperature (39.2°C) in aqueous solution which was a little higher than the human body temperature. Polymeric micelles PM73 showed a unimodal size distribution with an average diameter of 24.2±0.5 nm. The micelles were thermodynamically stable in aqueous media above the critical micelle concentration (1 mg/l). The anti-inflammation drug, prednisone acetate, was incorporated into PM73 as the model drug. The loading capacity was found to be around 8 wt%, and the drug-loaded micelles showed similar size distribution patterns (monodisperse with an average diameter of 32.1±0.5 nm) and morphology (spherical) to the empty micelles. The drug-loaded micelles showed remarkable thermoresponsive drug release behavior, in response to the micellar structural change. These results suggest that the nano-size polymeric micelles might be useful as drug carriers to achieve the site-specific delivery of drugs.

	Abstract:A series of new smectic side-chain chiral liquid crystalline polymers were prepared having nematic monomer and non-mesogenic chiral monomer. All polymers were synthesized by graft polymerization using polymethylhydrosiloxane as backbone. The mesomorphic properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and X-ray diffraction measurements（XRD）. The chemical structures of the monomers and polymers obtained were confirmed by Fourier transform infrared (FTIR), proton nuclear magnetic resonance spectra(1H NMR). M1 showed nematic phase during the heating and the cooling cycle. Polymer P1-P4 were chiral smectic A phase, while P5、P6 were chiral smectic C(SC*) phase. P7 showed bad LC properties and the mesomorphic properties of P8 had been disappeared. Experimental results demonstrated that the glass transition temperatures、the isotropization temperatures decreased with increasing the content of the chiral unit. The chiral agent offered helicity and at the same time provided diluting action.

	Abstract:A series of new cholesteric side-chain chiral liquid crystalline polymers were prepared containing cholesteric monomer and non-mesogenic chiral monomer. All polymers were synthesized by graft polymerization using polymethylhydrosiloxane as backbone. The mesomorphic properties were investigated by differential scanning calorimetry(DSC), polarizing optical microscopy(POM) and X-ray diffraction measurements(XRD) and temperature-changing solidistic optical rotation(TCSOR). The chemical structures of the monomers and polymers obtained were confirmed by Fourier transform infrared (FTIR), proton nuclear magnetic resonance spectra(1H NMR). M1 showed cholesteric phase during the heating and the cooling cycle. Polymer P1 were chiral smectic A phase, while P2~P8 were cholesteric phase. Experimental results demonstrated that non-mesogetic chiral moity offered the possibility of application due to its lower glass transition temperature and the glass transition temperatures and isotropization temperatures reduced, and the ranges of the mesophase temperature changed abruptly at first and then smoothly with increasing the content of chiral agent.

	Abstract:Side chain liquid crystalline (LC) poly(meth)acrylates with end-on bent-core liquid crystalline (BCLC) mesogens were synthesized. The resulting polymers exhibit thermotropic LC behavior. SmCP phases were observed for both monomers and polymers. In LC monomers, typical antiferroelectric switching was observed. In the corresponding polymers, a unique bilayer structure was observed, which is different from the reported BCLC bilayer SmCG phase.
