摘要

Growing environmental concern over the elimination of non-degradable packaging cover is increasing higher in each year, due to their hazardous pollution creating substance, while it comes to the degradation. As a result, the present study aims to investigate the biodegradable PVA and bio-extracted ZrO2 nanofiller-reinforced composite and also evaluate their performance by studying their mechanical, thermal conductivity, wear, dielectric and contact angle properties. Further, the extraction of ZrO2 from Phyllanthus niruri treated under silane coupling agent is the novelty of study. By under solution casting method, the PVA and ZrO2 nanofiller-reinforced composite was developed. The mechanical thermal conductivity, wear, dielectric and contact angle properties are analysed as per ASTM standard. Based on the study observations, composite PP2 with 2 vol.% of ZrO2 particle shows better tensile strength of 61.8 MPa, tensile modulus of 2.29 GPa and tear strength of 31.4 N/mm and it is 34.34%, 27.2%, 38.93% higher when compared to plain PVA composite. While the composite PP4 with reinforcement of 4 vol.% of ZrO2 particle shows maximum hardness, specific wear rate, coefficient of friction, thermal conductivity, dielectric permittivity, dielectric loss and water contact angle properties of 42 shore-d, 0.014, 0.28, 2.34 W/mK, 5.1, 0.79, and 72°, it is 53.48%, 73%, 30%, 93.38%, 121%, 79.5%, 46.93% higher than plain PVA composite PP0. Phyllanthus niruri ZrO2 particles treated with silane coupling agent exhibit superior strength to PVA matrix composite and could be of utilization in applications requiring less dense, biodegradable, good microbial resistance, thermal, water, wear resistance and better load dispersing packaging cover, electrical sensing device, coating in the automotive household sector, etc.
