Abstract

This research aims to investigate the properties of a novel packaging material composed of polyvinyl alcohol (PVA) films with treated carbon nanotube (CNT) mix, stacked with poly lactic acid (PLA) films. The PVA-CNT mix was prepared by treating the CNTs with a silane coupling agent, which improved the dispersion and compatibility of the CNTs in the PVA matrix. The PVA-CNT films were then stacked with PLA films to form a multilayered structure. The mechanical, thermal, and barrier properties of the PVA-CNT/PLA film were characterized using various analytical techniques. The results showed that the PVA-CNT mix improved the mechanical strength and thermal stability of the PVA film. The tensile strength of CNT reinforced film obtained 14.16 N/mm2 and shows higher TEAR Force 3.37 N as well as without treat showed 3.37 N/mm2 and 3.03 N. In TGA analysis, maximum degradation temperature 348.70 0C and weight loss was recorded 59.90 %. CNT mixed film has the maximum DTG 1.435 mg/min at 350.0 0C. This manuscript presents a new step in the field of sustainable materials to develop high-performance, biodegradable packaging solutions. By incorporating processed carbon nanotubes (CNTs) with polyvinyl alcohol (PVA) and poly-lactic acid (PLA), they achieve significant improvements in mechanical strength, thermal stability, and barrier.
