Thermosensitive hydrogels based on N-isopropylacrylamide (NIPAAm) and 2-hydroxyl ethyl acrylate (2-HEA) were synthesized with different composition ratios at 50:50 and 70:30 mol% using ammonium persulfate as free radical initiation system. The hydrogel was characterized by Fourier transform infrared spectroscopy (FTIR). The interpolymer complex between hydrogels and linear with poly(acrylic acid) (PAA) with different molecular weight was studied. The effect of pH, molecular weights, inorganic salt (NaCl) as well as surfactants concentrations on the complexation was investigated. The swelling behavior of the thermosensitive hydrogels in PAA solutions went up with increasing pH and molecular weight of PAA. However, the decreasing the concentration of surfactants sodium dodecyl sulfate (SDS) and cetylpyridinium bromide (CPB) increased the swelling behavior of hydrogels.

热敏 N-异丙基丙烯酰胺 -CO-2-羟乙基丙烯酸酯水凝胶与聚（丙烯酸）和表面活性剂的相互作用

以过硫酸铵为自由基引发体系，以 50:50 和 70:30 mol% 的不同组成比合成了基于 N-异丙基丙烯酰胺 (NIPAAm) 和 2-羟基乙基丙烯酸酯 (2-HEA) 的热敏水凝胶。水凝胶通过傅里叶变换红外光谱（FTIR）表征。研究了水凝胶和线性与不同分子量的聚（丙烯酸）（PAA）之间的互聚物复合物。研究了 pH、分子量、无机盐 (NaCl) 以及表面活性剂浓度对络合的影响。热敏水凝胶在 PAA 溶液中的溶胀行为随着 PAA 的 pH 值和分子量的增加而上升。然而，
