摘　　要：导电压敏胶是以相对分子质量为2000的聚酯二醇(PEA2000、PBA2000、PHA2000)为单体,通过调节异氰酸根与羟基的摩尔比(n(-NCO)∶n(-OH))得到不同相对分子质量的聚酯聚氨酯丙烯酸酯大分子交联剂。将其与功能性单体丙烯酸(AA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS),小分子交联剂N,N-亚甲基双丙烯酰胺(MBA)以及KCl在甘油和水的混合溶剂中按一定的比例混合,通过紫外光固化得到导电压敏胶。表征了大分子交联剂的组成和结构,结果表明通过调控异氰酸根与羟基的摩尔比,成功地得到不同相对分子质量的聚氨酯大分子交联剂;然后对压敏胶进行相关性能的测试。结果表明,其中以PUA-PBA2000(-NCO∶-OH摩尔比为1.4)为大分子交联剂制备的压敏胶力学性能最好,并且具有较好的导电性和亲水性;因此,在医用电极方面有很好的应用前景。In this study, polyester diol (PEA2000, PBA2000, PHA2000) with a molecular weight of 2000 was used as monomer. Various molecular weights of polyester polyurethane acrylate macromolecular crosslinkers were obtained by adjusting the mole ratio of isocyanate to hydroxyl (n(-NCO)∶n(-OH)), then mixed with functional monomers acrylic acid (AA)and 2-acrylamide-2-methylpropane sulfonic acid (AMPS), small molecule crosslinker N,N-methylenebisacrylamide (MBA) and KCl in the a mixture of glycerol and water. The solution was prepared and UV cured for making pressure sensitive adhesive(PSA). The composition and structure of the macromolecular cross-linker were characterized. The results show that by adjusting the mole ratio of isocyanate to hydroxyl group, polyurethane macromolecular cross-linkers of various molecular weight can be obtained;then the performance of pressure sensitive adhesives was characterized. PSAs shows the best mechanical property when PUA-PBA2000 (the mole ratio of n(-NCO)n(-OH) is 1.4) is used as macromolecular crosslinker. PSAs has a good conductivity and hydrophilicity, indicating a very good application prospect in medical electrodes.
