Polymer nanocomposites offer various functional advantages required for several biomedical applications. For example, polymer nanocomposites are biocompatible, biodegradable, and can be engineered to have mechanical properties suitable for specific applications. The key to the use of polymer nanocomposites for different applications is the correct choice of matrix polymer chemistry, filler type, and matrix-filler interaction. This paper discusses the results of a study in the processing and characterization of nono-filled polymer composites and focuses on the improvement of its properties for potential biomedical applications. The experimental procedure for the preparation of nano-filled polymer composite by ultrasonic mixing is described. Different types of nanofillers and polymer matrix are studied. Effects of processing parameters such as percent loading of fillers, mixing time on the mechanical properties of the composites are discussed. Preliminary results indicate improvement in shear and flexural properties, tensile and compressive properties, were observed in the prepared composites for some processing conditions.

Authors investigated the relationship among processing parameters, microstructures, electrical conductivity and mechanical property of injection molded nanoparticle filled polymer composites at present study. Standard tensile specimens were injected under different injecting pressures and packing pressures. The molded specimens were removing five layers from the surface to observe the microstructures at different positions of the moldings. The electrical properties were measured with a two-terminal standard resistor under DC condition at room temperature, and the mechanical properties of the moldings were measured by INSTRON 5580 Universal testing machine. The results showed that filled nanoparticles may form the best conductive path under the higher packing pressure matched with higher injection pressure. The mechanical properties of the molding depend on not only the concentration of the nanofiller, but processing conditions as well.
