Abstract

Nanocomposite materials refer to those materials whose reinforcing phase has dimensions on a scale from one to one hundred nanometers. In this study, the nanocomposite biodegradation of the phenol Novolac epoxy and the unsaturated polyester resins was investigated using the egg shell nanoparticle as bioceramic as well as starch and glycerin as natural polymers to modify their properties. The phenol Novolac epoxy resin has a good compatibility with the unsaturated polyester resin. The prepared samples with different composition of materials for specified time were buried under soil and their biodegradation was studied using FTIR and SEM. The FTIR results before and after degradation showed that the presence of the hydroxyl group increased the samples degradation. Also adding the egg shell nanoparticle to samples had a positive effect on its degradation. The SEM results with and without the egg shell nanoparticle also showed that use of the egg shell nanoparticle increases the samples degradation. Additionally, increasing the amount of starch, and glycerol and the presence of egg shell nanoparticles can increase water adsorption.

天然聚合物降解苯酚-环氧树脂/不饱和聚酯树脂/纳米蛋壳复合材料的研究

纳米复合材料是指增强相尺寸在1 ~ 100纳米之间的材料。本研究以蛋壳纳米粒子为生物陶瓷，以淀粉和甘油为天然聚合物，对苯酚环氧树脂和不饱和聚酯树脂进行纳米复合生物降解研究。苯酚环氧树脂与不饱和聚酯树脂具有良好的相容性。采用FTIR和SEM研究了不同材料组成的制备样品在土壤中埋藏一定时间后的生物降解情况。降解前后的FTIR结果表明，羟基的存在促进了样品的降解。在样品中加入蛋壳纳米粒子对其降解也有积极的影响。添加和不添加蛋壳纳米颗粒的SEM结果也表明，使用蛋壳纳米颗粒增加了样品的降解。此外，增加淀粉和甘油的量以及蛋壳纳米颗粒的存在可以增加水的吸附。
