Control
of heterogeneous ice nucleation (HIN) on foreign surfaces is of great
importance for anti-ice-nucleation material design. In this work,
we studied the HIN behaviors on various ion-modified poly(butylene
succinate) (PBS) surfaces via chain-extension reaction. Inspired by
antifreeze proteins (AFPs), the PBS-based polyampholytes, containing
both negative and positive charge groups on a single chain, show excellent
performance of ice nucleation inhibition and freezing delay. Unlike
the extremely high price and low availability of AFPs, these PBS-based
polyampholytes can be commercially synthesized under mild reaction
conditions. Through water freezing tests on a wide range of substrates
at different temperatures, these PBS-based polyampholytes have shown
application value of tuning ice nucleation via a simple spin-coating
method.
