The biodegradation is becoming one of the most imperative properties of plastic products nowadays to promote the sustainable development and the conservation of the environment. In this framework, the main objectives of this study are to prepare an environmental friendly high density polyethylene (HDPE) nanocomposite and investigate the effect of the incorporation of nanoparticles of calcium carbonate (NPCC) and poly butylene succinate (PBS) on the prepared nanocomposites. The nanocomposites of HDPE/PBS/NPCC samples were prepared by the addition of PBS and NPCC at (1, 2 and 4 wt%) to HDPE matrix using the injection molding technique. Morphological, mechanical, thermal, physical and biodegradation analysis were conducted on the nanocomposite samples. The mechanical properties of the samples were improved (the elongation at break by 35%, and the impact strength by 26%) compared to the neat HDPE. Moreover, the thermal and physical properties were enhanced by reinforcement NPCC to the nanocomposites. The biodegradation occurrence in the HDPE nanocomposite samples was proved by the Scanning Electron Microscope (SEM) observations and the weight loss percentage (0.265 wt% after 8 weeks).

为了促进可持续发展和环境保护，生物降解正成为当今塑料产品最重要的特性之一。在此框架下，本研究的主要目的是制备一种环境友好的高密度聚乙烯（HDPE）纳米复合材料，并研究掺入碳酸钙（NPCC）和聚丁二酸丁二醇酯（PBS）纳米颗粒对制备的纳米复合材料的影响。HDPE / PBS / NPCC样品的纳米复合材料是通过使用注射成型技术向HDPE基质中添加1、2和4重量％的PBS和NPCC制备的。对纳米复合材料样品进行了形态，机械，热，物理和生物降解分析。样品的机械性能得到改善（断裂伸长率为35％，冲击强度比纯HDPE高出26％）。而且，通过将NPCC增强至纳米复合材料，增强了热和物理性能。HDPE纳米复合材料样品中的生物降解发生是通过扫描电子显微镜（SEM）观察和失重百分比（8周后为0.265 wt％）证明的。
