Contrasting nanoscale surface morphologies of polyurethanes containing polyoxetane soft blocks with random and block segmer sequences


The effect of shock block sequence distribution on surface morphology and wetting behavior was analyzed. It was observed that polyurethanes such as PU-1 were highly effective in modification of the surface of conventional polyurethanes. It was also observed that the polyurethanes were prepared using polyoxetane telechelics or a reference PTMO soft segment. It was found that polyurethanes had different nanoscale morphologies and water contact angle was dependent on soft segment sequence.
