Effects of compounding conditions on tensile properties of polyamide 12/clay nanocomposites

Nanocomposites are materials, which have been studied since 90th years of last century, but manufacture of nanoscale materials is at least a 100-year-old industry (particles of carbon black as fillers in automotive tires). The field of nanotechnology is one of the most popular areas for current research and development in virtually all technical disciplines. Seeking for new materials with better properties, scientists are lately more and more dealing with nanocomposites. Important class of nanocomposite materials are polymer layered silicates, in which layered filler (mostly modified natural clay minerals) is dispersed in polymer matrix. Many of parameters (i.e. type of polymer matrix, type and amount of nanofiller, and a number of process parameters as melting parameters, screw speed, number and shape of mixing screws etc.) affect properties of nanocomposites. The paper deals with mechanical properties of polyamide 12/clay nanocomposites prepared by a melt-intercalation technique. The aim of the investigation was to determine the influence of compounding conditions, screw rotation speed and mixing temperature on tensile properties of PA12/clay nanocomposites.
