摘要
采用聚硅氧烷 -聚氨酯共聚物作为表面改性添加剂对热塑性聚氨酯进行共混改性。接触角和ESCA测定结果表明 :聚硅氧烷向共混物表面迁移 ,富集在共混物表面 ,使其接触角增大 ,具有憎水性。
Thermoplastic polyurethanes were blended with poly(siloxaneurethane) as sufrace modifying agent.The results of ESCA showed poly(siloxane) moved to and was rich on the surface of the blend,making the angle of contact big,being hydrophobic.
