Novel production of functional surfaces for ice growth inhibition by applying an antifreeze polypeptide and a silane coupling agent

Abstract

We have produced new functional surfaces for restraining the solidification of water by adhering antifreezepolypeptides on the surfaces. To examine the effectiveness of the surfaces, we conducted simultaneously themeasurements of temperature inside a water droplet on the cooling surfaces with a fine thermocouple and theobservation of solidification of the droplets with a video microscope. It was found from the results that aglass surface with antifreeze polypeptides showed a remarkable inhibition of ice growth.
