Control over the Structure of Ice and Water by Block Copolymer Additives

Antifreeze proteins protecting against ice crystallization have biomimetic analogons in block copolymers poly(ethylene oxide)–poly[2‐(2‐hydroxyethyl)ethylene] and its partially phosphorylated derivative. Both polymers influence the structure of liquid and solid water to a greater extent than the pro...

Description
Summary:Antifreeze proteins protecting against ice crystallization have biomimetic analogons in block copolymers poly(ethylene oxide)–poly[2‐(2‐hydroxyethyl)ethylene] and its partially phosphorylated derivative. Both polymers influence the structure of liquid and solid water to a greater extent than the proteins, as shown by an excess increase of the average water density (as shown in the graph), water viscosity changes, additional exothermic enthalpic transitions close to the freezing point, as well as changes of the ice unit cell.
