摘要: 研究了氟碳链改性的聚丙烯酰胺水溶液的溶液性质及其对盐浓度的依赖性,重点考察了氟碳疏水组分含量盐浓度对特性粘数的影响,以及粘度随剪切速率和温度的变化关系.结果表明聚合物溶液的粘度随盐的引入而增大,但在两种溶液中最小值对应的共聚单体含量一致.随温度的增加,共聚物溶液粘度依次出现了最小和最大值.所有实验结果均归于溶液中存在的疏水和氢键两种相反作用的综合结果.
英文摘要: The properties of fluorocarbon-modified polyacrylamide aqueous solations are investigated . Including rheological behavior, intrinsic viscosity and their dependence on temperature and the addition of salts . It is found that hydrogen bond strength and hydrophobic association of the solutions are remarkably influenced by the content and chemical structure of the hydrophobic co-monomers . The viscosity reaches a minmum when molar content of the co-monomers is 0.14%, and all samples ' viscosity increases with the addition of salts . With the increase in temperaturs, there exist two peaks corresponding to the minimum and maximum viscosity. All the experimental results could be explained by the competitive contribution to viscosity from hydrogen interaction and hydrophobic association in the solutions .
