Fibre based bioplastic film from Morus sp. (mulberry) leaves for medical purpose

摘要

New trend was shown the application of biodegradable plastic was used in the medicinal field especially as a template for the 3rd and 4th degree of burning is extensively studied. Currently, a bioplastic in medicinal applications for burning treatment comes from various materials based on fossil oil and synthetic chemical. Morus sp. among abundant plant and normally used for skin and inflammation treatment in traditional practices. The aim of this research is to synthesis bioplastic by using Polyvinyl alcohol (PVA) incorporates with Morus sp. leaves as the alternative of the skin template for a burning patient. With the phytochemical in the leaves such as phenolic, flavonoid and high content of antioxidant, hopefully, it will able to enhance the cell growth on the burning site without any contamination from the bacteria. 2 g Morus sp. leaves was blend with different concentration of the PVA (20%, 40%, 60%, 80%, and 100%) to produce plastic films. This mixture was stirred under constant magnetic stirring at 95°C for 1 hour. The mixtures are then pouring into a glass petri dish and dried in an oven at 50°C for 24 hours. The characterization of bioplastic is based on an antimicrobial test, tensile test, microstructure analysis using SEM and chemical composition analysed using FTIR. According to the results, a bioplastic made up from mixes Morus sp. leaves with 80% PVA has the best mechanical and antimicrobial properties. Therefore, the result showed a possible application of the film as an alternative for the medical purpose.
