Abstract
In this research, development of fluoropolymer nanocomposites was investigated. Fluoroelastomer (FKM) nanocomposites were prepared by melt mixing in a Haake rheometer and then the post cure and preparation of the test samples were carried out using compression molding. Effects of different nanofillers on fluoroelastomer vulcanization, mechanical and dynamic properties, and thermal stability were studied. It was found that the tested nanofillers had significantly different effects on the vulcanization of the fluoroelastomer, which in turn led to different mechanical, thermal dynamic, and thermal stability properties. In addition, a novel type of fluorothermoplastic elastomer (F-TPE) nanocomposites, were prepared by dynamic vulcanization method. The fluoroelastomer was partially vulcanized during blending and was cured further in a subsequent post cure process. Nanoclay, nano silica and expanded graphite were added to the blends and their effects on morphology, mechanical, dynamic, and thermal properties of the blends were studied. The nanofillers appeared to preferentially reside in the elastomer phase of the blends. It was also found that all the nanofillers could increase the mechanical properties and storage modulus of the F-TPE blends. Thermal stability of the blends was influenced differently depending on the nanofiller type.
