Abstract

Biodegradable polymers were broadly utilized to diminish plastic waste for ecological sustainability. Therefore the current study aims to prepare the novel ecofriendly Phyllanthus reticulatus fruit extract (PRFE) functionalized Chitosan (CH)—Poly (vinyl alcohol) (PVA) blend flms by employing cost efective solvent casting method. The obtained CH/PVA/PRFE blend flms were coded as CPP. The efect of diferent amounts of PRFE (2 mL, 4 mL, 6 mL and 8 mL) on the physicochemical properties of CH/PVA flm was investigated successfully. The presence of intermolecular hydrogen bonding between the components of the blend flm was confrmed by Fourier Transform Infrared Spectroscopy. The incorporation of PRFE into the CH/PVA matrix signifcantly (P<0.05) enhanced the mechanical properties such as tensile strength and Young’s modu�lus whereas elongation at break was decreased when the concentration of PRFE was 2 mL and 6 mL respectively. The CPP blend flms revealed smooth surface morphology, lower water vapour transmission rate and water solubility at lower content (2 mL and 4 mL) of PRFE whereas oxygen permeability, water contact angle, water absorption capacity, % transmittance and transparency of the CPP flms were decreased as the concentration of the PRFE increased in the CH/PVA matrix. The CPP blend flms showed a superior soil degradation rate this indicates the flms are biodegradable in nature. Further, the CPP flms showed extensive antimicrobial properties in comparison with CH/PVA flm. These results demonstrate that the prepared blend flms have a potential application in the eco-friendly packaging feld. All the tests were carried out in triplicate and the mean values were determined by the Tukey test (p≤0.05).
