Abstract
The widespread use of non-biodegradable polymers exacerbates problems with global warming and other environmental difficulties. These problems necessitate the development of biodegradable polymers as a solution. In this research, we analyze the utilization of crosslinked polymer by its processing of polyvinyl alcohol (P V A) crosslinked with glutaraldehyde (G L U T). After curing for 24 hours in 2 moles of sulfuric acid (H2SO4), the plasticized alcohol has been cross-linked from 0 % to 4 0 % by volume of glutaraldehyde. The Shore D hardness of P V A and P V A cross-linked G L U T polymer composites was measured using an Excel Durometer by ASTM D2240 standards. The polymer’s hardness is increased by as much as 15% thanks to the crosslinking effect of glutaraldehyde, and minor further improvements are discovered. The Tukey HSD test determines the cutoff for statistical significance and the optimal crosslinking percentage. Tukey’s test for multiple comparisons indicates that a f value greater than 5.35 is statistically meaningful.This study focuses mainly on the significant improvement in the hardness of polyvinyl alcohol (PVA) when crosslinked with glutaraldehyde. The research found that the hardness of the polymer improved by up to 15% due to glutaraldehyde crosslinking. This study also suggests a research investigation into the effects of crosslinking polyvinyl alcohol (PVA) with glutaraldehyde on the toughness properties of the material. The widespread use of non-biodegradable polymers has raised concerns related to global warming and environmental issues. To address these challenges, biodegradable polymers are essential. In this study, we focus on polyvinyl alcohol (PVA) crosslinked with glutaraldehyde (GLUT) and investigate the hardness of the resulting crosslinked polymer.
