疏水缔合聚合物HAWP与芥酸酰胺丙基烯丙基溴化铵复合体系流变和界面性能研究
Study on rheological and interfacial properties of a synergistic mixture of hydrophobically associating polymer HAWP and erucamidopropyl allyl ammonium bromide
摘要
Abstract
In view of the limited abilities of hydrophobically associating polymers to increase viscosity and improve interfacial activity, a synergistic system composed of a hydrophobically associating polymer and a cationic surfactant was proposed. In this work, the hydrophobically associating polymer HAWP and the cationic surfactant erucamidopropyl allyl ammonium bromide (EDAA) were mixed to construct the synergistic system (EDHA). The viscosity-increasing mechanism of the synergistic system was studied by scanning electron microscopy, rheometer and cyclodextrin inclusion method. The effects of pH, NaCl mass concentration and temperature on the rheological properties and the ability to reduce interfacial tension were also explored. The results showed that the synergism of the mixed system was based on hydrophobic association and electrostatic attraction. With the increase of pH, the viscosity and viscoelasticity of the synergistic system first increased and then decreased, and the interfacial tension first decreased and then increased. The viscosity and viscoelasticity of the synergistic system were decreased with the increase of NaCl mass concentration, and the interfacial tension was first increased and then decreased. The viscosity and viscoelasticity of the system were decreased and the interfacial tension was increased with the increase of temperature.关键词
