亲水/疏水互穿网络水凝胶的合成及其pH敏感特性研究
Studies on synthesis and pH sensitivity of hydrophilic hydrophobic interpenetrating polymer network
【摘要】 利用 I P N 技术合成了聚(丙烯酸)/ N—十二烷基聚(4—乙烯吡啶)溴化盐( Q P V P D-30)半互穿网络水凝胶。这种水凝胶在弱碱条件下的溶胀率远大于酸性条件下的溶胀率。并且随着 Q P V P D—30 用量的增加其溶胀率下降
【Abstract】 The new hydrogel was prepared by using interpenetrating polymer networks (IPN) technique. Poly (acrylic acid)/N dodecyl poly(4 vinyl pyridine) (PAAc/QPVPD 30) semi INP hydrogel was synthesized. The Swelling Ratio(SR) of this hydrogel in weak alkaline solution is much greater than that in acidic solution. Experimental results revealed that its SR decreases as the percent of QPVPD-30 is increased.
