【摘要】 对pH敏感性水凝胶的合成方法和作用原理进行了综述。pH敏感性水凝胶的合成方法主要包括交联聚合、接枝共聚和互穿网络三种方式;pH敏感性水凝胶具有pH响应性的原因是聚合物网络中含有可离子化的酸性或碱性基团。更多还原

【Abstract】 The synthetic methods and reaction principles of pH - sensitive hydrogels are reviewed. There are three synthetic methods for pH - sensitive hydrogels - cross linking polymerization; graft copolymerization and interpenetrating polymer net work. The polymer net work of pH - sensitive hydrogels has ionizing basic or acidic group which causes pH responding behavior.更多还原
