摘要
近年出现的用冷等离子体处理填料的方法被认为是偶联剂技术的一个新发展。它是通过等离子体作用,使填料表面产生有利于与基体树脂相容的结构变化,从而实现改善填充体系使用和加工性能的目的。这种处理方法具有作用强度大而穿透力小、效率高,无公害等特点。与采用硅烷、钛酸酯偶联剂等较成熟的处理方法不同,等离子体处理的研究尚在起步阶段,基本局限于对处理效果的探讨,有关处理对填充体系结构影响的研究尚不多见。本文以经乙烯等离子体处理的云母为填料,初步研究了填料与HDPE、IDPE及PS界面的水扩散特性、界面极化特性,以及基体的松弛转变行为。
The effects of ethylene plasma treated mica on interface structure of mica/high density polyethylene (HDPE), low density polyetylene (LDPE) or polystyrene (PS) as well as bulk structure of the matrices were studied. The experimental results of dielectric loss and moisture content of the filled polyolefines show that the uniformity and hydrophobicity of the filler/ matrix interface are enhanced by the plasma treatment. The DSC and dynamic viscoelastic spectroscopy data indicate that the plasma treatment might weaken the rigidifying effect of the filler on macromolecules of, PS, and has no influence on the relaxation behavior of HDPE and LDPE.
