Abstract

In present work, Semolina being used as biomass served to be the polymer matrix within which ZnO nanoparticles were incorporated. ZnO nanoparticles were biogenically synthesized using Syzygium cumini extract to avoid any hazardous side products. FT-IR analysis of ZnO reinforced Semolina plastic blends revealed hydrogen bond formation between the starch polymer matrix and nanoparticles. Moisture content test was performed which proved the decrease in the moisture content with an increase in ZnO NPs concentration where 9.7% served to be the lowest value by 10% ZnO blend. The water solubility test also confirmed this decreasing trend while increasing water resistance and antimicrobial activity was also confirmed. The cell cytotoxicity test was performed on the fibroblast cells where the 5% ZnO blend confirmed to be cytotoxic. The biodegradation of the 5% ZnO blend confirmed the faster rate of mineralization at the start while decreasing through time.

摘要

在当前的工作中，用作生物质的粗粒小麦粉用作其中掺入了ZnO纳米粒子的聚合物基质。ZnO纳米粒子是用孜然酵母（Syzygium cumini）生物合成的提取避免任何有害的副产品。ZnO增强的粗面粉塑料共混物的FT-IR分析表明，淀粉聚合物基质和纳米颗粒之间形成氢键。进行了水分含量测试，该测试证明了水分含量随ZnO NPs浓度的增加而降低，其中9.7％是ZnO掺入10％的最低值。水溶性测试也证实了这种下降趋势，同时也证实了增加的耐水性和抗菌活性。在成纤维细胞上进行了细胞毒性试验，其中5％ZnO混合物被证实具有细胞毒性。5％ZnO共混物的生物降解过程证实了开始时矿化速度更快，但随着时间的流逝而降低。
