溶液等离子体处理是制备复合材料的有效方法。为了优化溶液中的等离子体处理，需要一种能够充分评估表面修饰的方法。在本研究中，为了确定这种方法，在溶液中采用等离子体处理改性的六方氮化硼（hBN）颗粒，并具有不同的zeta电位，制备了聚轮烷复合材料。在对苯二酚溶液中等离子体处理产生具有高zeta电位的hBN粒子，命名为HQpBN， x射线计算机断层扫描显示HQpBN/聚轮烷复合材料均匀分散。HQpBN/聚轮烷复合材料的抗拉强度和伸长率是未改性的hBN/聚轮烷复合材料的两倍，其中hBN颗粒聚集。这些结果表明，改性颗粒的zeta电位可以作为一个指标，指导在溶液中等离子体处理过程中最佳的表面改性，以制备均相复合材料。
Plasma processing in solution is effective for the preparation of composites. To optimize the plasma processing in solution, a method that can be used to sufficiently evaluate the surface modifications is necessary. In this study, to identify such a method, hexagonal boron nitride (hBN) particles modified by plasma processing in solution and exhibiting different zeta potentials were used to prepare a polyrotaxane composite. Plasma processing in a hydroquinone solution yielded hBN particles with a high zeta potential, named HQpBN, and x-ray computed tomography showed a uniform dispersion of the HQpBN/polyrotaxane composite. The tensile strength and elongation of the HQpBN/polyrotaxane composite were twice as high as those of an unmodified hBN/polyrotaxane composite, in which hBN particles aggregated. These results demonstrate that the zeta potential of the modified particles can be used as an indicator to guide optimal surface modification during plasma processing in solution for the preparation of homogeneous composites.
