摘要

研究了丙烯酸凝胶与膨润土、爆轰纳米金刚石等无机填料制备聚合物复合材料，以改善凝胶的物理力学特性。基于动态模对频率的依赖关系，采用振荡流变学方法研究了这些材料的流变特性。讨论了所研究的填料对凝胶动态模量和力学损失角切线的影响

STUDY OF THE MECHANICAL CHARACTERISTICS OF POLYMER COMPOSITE MATERIALS BASED ON ACRYLIC HYDROGELS AND INORGANIC NANOPARTICLES USING OSCILLATION RHEOMETRY

The production of polymer composite materials based on acrylic gels and such inorganic fillers as bentonite and detonation nanodiamonds, which make it possible to improve physical and mechanical characteristics of gels, was studied. Oscillation rheometry methods were used to study the rheological properties of these materials, based on the dependences of dynamic modules on frequency. The influence of the fillers studied on the values of dynamic modules and the tangent of the mechanical loss angle of the gel was discussed
