摘要
研究了温度敏感性聚合物聚 N异丙基丙烯酰胺在 P V A 膜上的共辐射接枝反应,及吸收剂量、剂量率、单体浓度、无机酸及 Cu2+ 浓度对接枝率的影响,同时测定了接枝膜的溶胀性能。结果表明 P V A 膜接枝后溶胀比增加且具有温度敏感性。
The direct radiation grafting of PNIPAAm onto PVA film is performed. The grafting conditions including the effects of absorbed dose, dose rate, concentration of monomer, acid and Cu 2+ on the grafting yield are studied. In the meantime, the properties of grafted film are determined. The result indicates that the PVA\|g\|PNIPAAm grafted film behaves with higher swelling ratio than pure PVA film and obvious temperature sensitivity.\;
