Abstract:

The thermal conductivity of polymers is one of the major technological barriers. Enhancing the thermal conductivity of the polymers is important for daily needs. In this work, we aim to increase the thermal conductivity of the polymer by introducing the Silicon Carbide (SIC) & Salt (NaCl) into the polystyrene (PS) polymer matrix. The effect of salt in the polymer is also investigated. Compounding of these materials using double screw co-rotational extruder to get granules and specimen is prepared by using an injection molding machine, The thermal conductivity is analyzed by using Thermogravimetric Analysis (TGA), the Impact strength is evaluated by Charpy-Impact test, Flexural modulus and Flexural strength are evaluated by 3- point bending test. The results reveal that salt improves thermal conductivity additionally to SIC; after studying internal microstructure, the results reveal that salt forms porosity inside polymer and SIC dispersion is uniform. The results were evaluated by sampling the specimen according to weight percentages. The silicon carbide nanoparticles can be used in injection molding, which leads to maximum design freedom for constructive.

Keywords:
