摘要:A series of fluorocarbon modified poly(acrylamide)s containing low amounts (0.1-1.5 mol%) of fluorocarbon (CF3(CF2)(5)-) are synthesized by copolymerization of acrylamide with 2-(perfluorohexyl) ethyl acrylate). The dynamic surface tension results show that the efficiency and effectiveness of the copolymers to lower surface tension increase with increasing the fluorocarbon content. The results of surface dilational viscoelasticity show that with the increase of the fluorocarbon content, the dilational viscoelasticity increases at the low concentration (< 0.5 wt%), but firstly increases and then decrease at high concentration (> 0.5 wt%). Furthermore, temperature has effect on the dilational viscoelasticity of the adsorbed layer in different extents.
