Synthesis and Characterization of Polymeric Composite Films by Designed Extruders

Polympropylene (PP) is extensively used in many industrial areas such as the automobile, household goods, packaging and electronic appliance properties applications due to its good performance and processing properties as well as low cost. Diatomite is a siliceous sedimentary rock. It has a unique combination of physical and chemical properties such as high porosity, high permeability, small particle size, large surface area and low thermal conductivity. For this purpose, in this study, the preparation of composite materials with good properties from a mixture of polypropylene and diatomite was considered. The surface of diatomite particles was treated by benzyltrimethylammonium chloride (BTMAC) and the diatomite filled polypropylene (PP) composites with a weight percentage range of the filler from 0 to 30% were prepared by means of melt blending in a designed single-screw extruder. The characterizations of the composite films synthesized by the laboratory type extruder were performed with FTIR, TGA, and SEM devices. Tensile strength tests were also performed for the mechanical properties of the synthesized films.
