Microwave Modification of Polymer-Carbon Materials
Studies of microwave radiation on polymeric materials have shown the possibility of modifying the characteristics of materials. At the same time, the efficiency of the microwave effect can be increased by introducing into the polymer matrix electrically conductive particles (carbon, metal particles, etc.). In this case, the absorption coefficient of the microwave waves is greatly increased. The paper evaluated the physical and mechanical properties of polyamide 6 subjected to microwave exposure. To intensify the microwave, well-proven carbon nanotubes were used, which were added to the polymer in small amounts. The most effective was the addition of carbon nanotubes in an amount of 1 wt%. The data obtained are changes in strength under tensile, Shore D hardness conditions, as well as thermophysical characteristics (heat resistance and change in the specific energy absorption rate in the melting zone of the samples). Microwave can be used as a modifying radiation, and as a method of heating polymers for subsequent molding in products. This method significantly reduces the technological process of obtaining materials and products with improved performance characteristics.
