亲水性与疏水性,结晶性与无定形,刚性与柔性等链段组合形成的嵌段或接枝共聚物,在固相会产生微观相分离,形成所谓的区域结构(domain)。具有区域结构的嵌段或接枝共聚物,做为一类新型的复合材料正被广泛地研究着。具有亲水性及疏水性区域结构的聚合物,同生物体有着密切的关系。现在已经知道,生 The block or graft copolymer, which is formed by combination of hydrophilic and hydrophobic, crystalline and amorphous, rigid and flexible segments, produces microscopic phase separation in the solid phase to form a so-called domain. As a new type of composite material, a block or graft copolymer having a domain structure is being extensively studied. Polymers with hydrophilic and hydrophobic domains have a close relationship with organisms. Now know, students
