Investigation of influence of conditions of obtaining PA6/MMT nanocomposites on their thermal properties

Abstract

The influence of additional thermal and thermomechanical treatment of PA6/MMT nanocomposites obtained from the formic acid solution on their heat resistance and technological properties was investigated. Thermal analysis established that heating the nanocomposite to a temperature of 250 ºС and treating it on a capillary plastometer IIRT at a temperature of 230 ºС increases the degree of crystallinity and heat resistance of the samples. It is shown that additionally treated nanocomposites also have lower fluidity and significantly higher values of softening temperature.
