摘要

在设计带有分散填料的聚合物组合物时,所需的功能和机械性能是必不可少的。这种聚合物组合物的机械性能可以通过封装填料颗粒外壳厚度的变化而改变。论文表明,氧化铜 (I) 颗粒表面的聚乳酸聚合物外壳及其厚度会显著影响基于 ED-20 环氧树脂的聚合物复合材料的强度。这是由于封装颗粒与基体聚合物之间的相互作用造成的,而非封装颗粒则不同。此外,由于外壳厚度增加而导致的颗粒尺寸变化也会影响组合物的强度特性。研究表明,填充环氧树脂复合材料的弹性模量与颗粒表面的外壳厚度无关。

Epoxy resin mechanical properties in composition with copper (I) oxide particles, encapsulated by polylactide with variable thickness
The required functional and mechanical properties are necessary for design the polymer compositions with dispersed fillers. The mechanical properties of such polymer composition can be changed by encapsulated filler particles shell thickness varying. The paper shows that the presence of polylactide polymer shell and its thickness on the surfaces of copper (I) oxide particles significantly affect the strength of polymer composite material based on ED-20 epoxy resin. That is due to the interaction between encapsulated particles and the matrix polymer, in contrast to noncapsulated particles. In addition, a change in particle size due to increasing shell thickness also affects the strength properties of the composition. It is shown that the elastic modulus of the filled epoxy composite does not depend on the shell thickness on the particle surfaces.
