| Summary: | The blend of PVA-CSNP is widely used in many industries and research fields such as packaging in the food industry, medical and pharmaceutical industries, as well as separation industries. Polymer blending can improve the membrane by combining two or more polymers in suitable ratios. CSNP was blended with PVA membrane to improve its properties. In this study, the CSNP polymer and PVA/CSNP membrane were synthesized and characterized. The synthesis of CSNP involved the application of CS at 0.5 wt.% and 1.0 wt.% at 1:1 and 1:2 ratios to STPP. The particle size and zeta potential for the 0.5 wt.% ratios showed significant outcomes for the study. The particle sizes were 892 nm and 975 nm, whereas the zeta potential showed significant cation values of +50.4 and +43.7 mV for the 1:1 and 1:2 ratios, respectively. The PVA membrane was developed using these nanofillers, and the functional group analysis showed molecular bonding throughout the membrane. The developed membrane also exhibited a smooth and dense structure, supporting good dispersion of CSNP within the membrane. To evaluate the physical strength of the membrane, the swelling index was measured, and a low degree of swelling confirmed the forecast that CSNP would reduce the hydrophilicity of the PVA membrane, subsequently providing good membrane strength. © 2024, SHPMedia Sdn Bhd.
