Polyvinyl alcohol is one of the important biodegradable polymers which gains worldwide consideration from the last decade for the development of biodegradable composite. Green plastic and composites based on polyvinyl alcohol show potential applications therefore polyvinyl alcohol is used as a matrix in the field of material science. In the present study, a modest attempt has been made to functionalized silicon carbide using acidic oxidation with nitric acid to obtain homogeneous stabilized distribution of activated SiC particles within a polymer matrix and develop functionalized silicon carbide (f-SiC) particle reinforced polyvinyl alcohol based cross-linked composite. After fabrication of functionalized silicon carbide (f-SiC) particle reinforced polyvinyl alcohol based cross-linked composite with varying f-SiC weight percentages of PVA (0%, 1%, 2%, 3%, 4%) were put to the investigation. Fabricated samples are firstly examined based on physical tests which consisted of the water absorption tests. Microstructural tests included the Scanning electron microscope (SEM), mechanical tests comprised of the tensile test. Finally, the thermal tests were also done which involved the Thermo gravimetric analysis (TGA), Differential thermal analysis (DTA) and Dynamic mechanical analysis (DMA). The polyvinyl alcohol-based cross-linked composite with 2 weight % of f-SiC content is confirmed to be the best of all compositions under this scrutiny which was authenticated by the microstructural and mechanical tests.ennullThesis
