Epoxy resins are important thermosetting polymers. They are widely used in many applications i.e., adhesives, plastics, coatings and sealers. Epoxy molding compounds have attained dominance among common materials due to their excellent mechanical properties. The sol-gel simple method was applied to distinguish the impact on the colloidal time. The properties were obtained with silica-based fillers to enable their mechanical and thermal improvement. The work which we have done here on epoxy-based nanocomposites was successfully modified. The purpose of this research was to look into the effects of cellulose nanocrystals (CNCs) on various properties and applications. CNCs have recently attracted a lot of interest in a variety of industries due to their high aspect ratio, and low density which makes them perfect candidates. Adding different amounts of silica-based nanocomposites to the epoxy system. Analyzed with different techniques such as Fourier-transformed infrared spectroscope (FTIR), thermogravimetric analysis (TGA) and scanning electronic microscopic (SEM) to investigate the morphological properties of modified composites. The various %-age of silica composite was prepared in the epoxy system. The 20% of silica was shown greater enhancement and improvement. They show a better result than D-400 epoxy. Increasing the silica, the transparency of the films decreased, because clustering appears. This shows that the broad use of CNCs in environmental engineering applications is possible, particularly for surface modification, which was evaluated for qualities such as absorption and chemical resistant behavior.
环氧树脂是重要的热固性聚合物。它们广泛应用于许多领域，即粘合剂、塑料、涂料和密封剂。环氧模塑料由于其优异的机械性能，在常见材料中占据主导地位。采用溶胶-凝胶简单方法来区分对胶凝时间的影响。通过二氧化硅基填料获得其性能，以实现其机械和热性能的改善。我们在此对环氧基纳米复合材料所做的工作得到了成功改进。本研究的目的是探究纤维素纳米晶体（CNCs）对各种性能和应用的影响。由于其高长径比和低密度，CNCs最近在各种行业引起了广泛关注，这使其成为理想的候选材料。向环氧体系中添加不同量的二氧化硅基纳米复合材料。采用傅里叶变换红外光谱仪（FTIR）、热重分析（TGA）和扫描电子显微镜（SEM）等不同技术进行分析，以研究改性复合材料的形态性能。在环氧体系中制备了不同百分比的二氧化硅复合材料。20%的二氧化硅表现出更大的增强和改善效果。它们比D - 400环氧树脂表现出更好的结果。随着二氧化硅含量的增加，薄膜的透明度降低，因为出现了团聚现象。这表明CNCs在环境工程应用中具有广泛应用的可能性，特别是对于表面改性，已对其诸如吸附和耐化学行为等性质进行了评估。
