Abstract

Plasticizers are essential additives in the processing of polyvinyl chloride (PVC), with phthalate plasticizers being widely used. However, these conventional plasticizers have been shown to be harmful to human health and environmentally unfriendly, necessitating the exploration of eco-friendly bio-based alternatives. In this study, Camellia oleifera seed oil, a specialty resource in China, was utilized as a raw material and reacted with 4,4′-Methylenebis(N,N-diglycidylaniline) (AG-80) to synthesize Phenyl Camellia seed Oil Ester (PCSOE). PCSOE was employed as a plasticizer to prepare modified PVC films with varying concentrations, with the conventional plasticizer dioctyl phthalate (DOP) serving as a control. Experimental results demonstrate that PSCOE-plasticized PVC films exhibit enhanced hydrophilicity, tensile strength, and thermal stability compared to DOP-modified PVC films. The contact angle of PSCOE-plasticized PVC films ranges from 66.26° to 78.48°, which is generally lower than the contact angle of DOP-modified PVC films at 78.40°, indicating improved hydrophilicity due to the modification with PCSOE. The tensile strength of PSCOE-plasticized PVC films ranges from 17.73 to 20.17 MPa, all surpassing the value of 16.41 MPa for DOP-modified PVC films. Moreover, the temperatures corresponding to 5%, 10%, and 50% weight loss for PVC samples modified with PCSOE are higher than those for DOP. Hence, PCSOE presents a viable alternative to DOP as a plasticizer for PVC materials.
