摘　　要：通过酸度、电导率、粘度、接触角的测定,研究了聚丙烯酸 (PAA) /聚丙烯酰胺 (PAM) 水溶液复合物及复合物膜的结构和性能。结果表明,酸度、温度、浓度和复合比影响PAA/PAM的复合水溶液中大分子链的构象和流体力学体积,适度的氢键作用可以形成均相的复合溶液。经过热处理和未经热处理的聚合物膜表现出了不同的亲水性能。The structure and performance of poly(acrylic acid) (PAA) with poly(acrylamide) (PAM) complex solution and the films of polymers were studied by means of acidity, conductivity,viscosity and contact angle. The results showed that formation and hydrodynamic volume of complex solution are influenced by the acidity,temperature,concentration and weight ratio of PAA/PVA complex solution. The homogeneous PAA/PAM complex solution can be obtained by means of proper hydrogen bonding between PAA and PAM. The polymer films with and without thermal treatment show different hydrophilicity.
