摘要:
利用自由基聚合机理合成聚丙烯酰胺水凝胶(PAAM)和聚丙烯酰胺/CaCu3Ti4O12杂合水凝胶(PAAM/CCTO)。研究表明，当将CaCu3Ti4O12(CCTO)纳米粉末引入到PAAM网络中后得到的PAAM/CCTO杂合水凝胶能保持较好的膨胀性，同时发现，通过调节CCTO的含量可以增强杂合水凝胶pH敏感性。
The P(AAM) hydrogels and P(AAM)/CCTO hybrid hydrogels were prepared by free radical poly-merization methods. The experimental results revealed that P(AAM)/CCTO hybrid hydrogels show a stronger pH-sensitivity and higher swelling properties by adjusting or modulating the concen-tration of the CCTO.
