In this paper, molecular dynamics simulations have been performed on poly(vinyl alcohol)-cryoprotective agent solutions. Four cryoprotective agents (CPA) were selected: DMSO, ethanol, ethylene glycol and glycerol. Hydrogen bonds were analyzed based on a geometrical criterion. The results showed that the number of hydroxyl groups in CPA molecules had a great impact on hydrogen bonding structure of PVA-CPA aqueous solutions.
Keywords:Refrigeration&Cryogenics; Hydrogen bond; Molecular dynamics simulation; Antifreeze
