Summary

Antifreeze protein (AFP), which is found in fish, insects, and plants living in cold regions, is well-known as an effective additive to inhibit agglomeration of ice slurries. However, AFP is currently too expensive and unstable to use in practical applications. In this article, polyvinyl alcohol (PVA) is proposed as a substitute for AFP. Images of ice surfaces revealed by scanning tunneling microscopy showed that adding PVA influences the morphology of ice surfaces. Observation of polycrystalline ice wafers showed that PVA is effective in inhibiting recrystallization of ice grains. Because these effects of PVA on ice growth and recrystallization are similar to those of AFP, PVA is expected to inhibit agglomeration of ice slurries at low concentrations.
