Abstract
The present disclosure relates to a method for preparing a self-cleaning anti-icing coating based on brushlike organosilicon. In this method, a brushlike organosilicon-modified polyurethane coating is prepared by subjecting a thiolactone, a diamine compound and monovinyl-terminated polydimethylsiloxane to a simple multi-component click reaction to obtain a dihydroxy-terminated block, and introducing the dihydroxy-terminated block into a polyurethane matrix.
