An amphiphilic polymer-based supramolecular system was formulated by exploring the electrostatic interactions between the cationic amphiphilic polymer and polyacid. The effect of aging time on the viscoelastic properties, salt and temperature tolerance, shear resistance, and viscosity recovery of the system was explored by means of rheological measurements. The intrinsic relationship between the viscoelasticity of the system at different aging times and their dynamic growth was studied by macro-rheological and optical micro-rheological methods. The results show that under the influence of various factors, the viscoelastic properties of the supramolecular system increase significantly with aging. Optical micro-rheological studies demonstrated that the viscoelasticity of the system continues to increase over a period of 30 days. After aging, the viscoelastic results indicate the formation of a strong gel. This study clearly demonstrates that the aging time is a key factor that should be considered in the formulation of supramolecular systems formed by the electrostatic interaction between the cationic amphiphilic polymer and polyacid.An amphiphilic polymer-based supramolecular system was formulated by exploring the electrostatic interactions between the cationic amphiphilic polymer and polyacid.

老化时间对两亲性聚合物-多元酸超分子溶液粘弹性的影响

通过探索阳离子两亲聚合物和多元酸之间的静电相互作用,配制了基于两亲聚合物的超分子体系。通过流变学测量研究了老化时间对系统粘弹性、盐和温度耐受性、抗剪切性和粘度恢复的影响。采用宏观流变学和光学微观流变学方法研究了体系在不同老化时间的粘弹性与其动态增长之间的内在关系。结果表明,在各种因素的影响下,超分子体系的粘弹性随老化显着增加。光学微流变学研究表明,系统的粘弹性在 30 天内持续增加。老化后,粘弹性结果表明形成了强凝胶。该研究清楚地表明,在阳离子两亲聚合物与多元酸之间静电相互作用形成的超分子体系的配制中,老化时间是应考虑的关键因素。阳离子两亲聚合物和多元酸。通过流变学测量研究了老化时间对系统粘弹性、盐和温度耐受性、抗剪切性和粘度恢复的影响。采用宏观流变学和光学微观流变学方法研究了体系在不同老化时间的粘弹性与其动态增长之间的内在关系。结果表明,在各种因素的影响下,超分子体系的粘弹性随老化显着增加。光学微流变学研究表明,系统的粘弹性在 30 天内持续增加。老化后,粘弹性结果表明形成了强凝胶。这项研究清楚地表明,老化时间是在制造过程中应考虑的关键因素。
