Abstract

The possibility for predicting tribological characteristics of polymer nanocomposites was studied with the example of nanocomposite poly (ether ketone)/graphene. It has been shown that the “escapement” effect of polymer matrix macromolecules by graphene surface essentially reduces (a several times) the indicated characteristics. The proposed simple structural model describes the obtained results through experiments. The fulfilled estimations indicate that the “escapement” effect of macromolecules by graphene surface results in a loss of 60–86% of the initial area of contact polymer matrix-nanofiller with a growth of graphene content up to 10 mas %. Thus, the improvement of the indicated contact (i.e., by nanofiller functionalization) likely leads to essential improvement of tribological characteristics of nanocomposite.

聚合物纳米复合材料的摩擦学参数预测

摘要

以纳米复合材料聚醚醚/石墨烯为例,研究了预测聚合物纳米复合材料摩擦学特性的可能性。已经表明,石墨烯表面对聚合物基体大分子的“逃逸”作用实质上降低了(若干倍)所示的特性。提出的简单结构模型通过实验描述了获得的结果。完成的估计表明,石墨烯表面对大分子的“逸出”效应导致接触聚合物基质-纳米粉的初始面积损失60-86%,而石墨烯含量的增长高达10 mas%。因此,所指示的接触的改善(即通过纳米填料功能化)可能导致纳米复合材料的摩擦学特性的本质改善。
