Research on Filled Modified Polymer

In the polymer filling system, because the chemical composition, geometry, particle size distribution, surface morphology and other properties of the filler are different, and the dispersion in the polymer and the interface structure are different, the filler is in the filled modified polymer Plays a different role.

The effect of the nature of the filler on the system. Reinforced fillers can improve the mechanical properties of plastics. The reinforcement effect can be improved by miniaturizing filler particles and surface treatment to replace higher-priced reinforcing materials; functional fillers can also give products conductivity, heat resistance and Various special properties such as degradability.

The influence of filler geometry and particle size on filling modification. The enhancement effect of flake and rod materials on the system is significantly higher than that of spherical materials. The smaller the particle size of the filler particles, the larger the specific surface area, and the more uniform the dispersion, the better the performance of the filler material. The surface treatment of the filler can reduce the surface energy to enhance its compatibility with the matrix resin and improve the dispersion ability. The existence of the filled polymer interface zone is an important reason for the special effects of this type of composite material.
