Development and Analysis of Poly Vinyl Alcohol/Orange peel powder biocomposite films

ABSTRACT

Environmental concerns are raised due to municipal solid wastes especially due to non-biodegradable packaging waste materials. To overcome such issues, researchers gained attention in biodegradable natural waste materials as an alternative to existing non-biodegradable packaging materials. In this work, Orange Peel Powder (OPP) chosen as a filler at varying proportion (5% to 20% of wt.) and polyvinyl alcohol (PVA) used a matrix to prepare biocomposite films by solution casting method. The films were analyzed with FT-IR, XRD, TGA, DSC, and tensile tests. The results of FT-IR and XRD show smooth dispersion of PVA and OPP, whereas samples are thermally stable up to 350°C & tensile properties of the prepared biofilms increased with inclusion of OPP from 6.20 MPa to 7.80 MPa and are better than the conventional-packaging materials which can be used as eco-friendly packaging materials.

摘要

城市固体废物，特别是非生物降解包装废物，引起了环境问题. 为了克服这些问题，研究人员在生物降解天然废物材料中引起了关注，作为现有非生物降解包装材料的替代方案. 在这项工作中，橙皮粉（OPP）选择作为填充物以不同的比例（5%至20%的wt.）和聚乙烯醇（PVA）使用基质制备生物复合膜的溶液铸造方法. 对薄膜进行了FT-IR、XRD、TGA、DSC和拉伸试验. FT-IR 和 XRD 的结果显示 PVA 和 OPP 平滑分散，而样品的热稳定性高达 3500C – 制备的生物膜的拉伸性能随 OPP 的加入而增加，从 6.20 MPa 增加到 7.80 MPa，并且优于传统封装 可用作环保包装材料的材料.
