Cellulose and its derivatives are widely explored for films and thickening of pharmaceutical solutions, in paints, as reinforcement in composites, among others. This versatility is due to advantages such as renewability, low cost, and environmental friendliness. When used in polymer composites, due to the hydrophilic character of the cellulose, surface chemical modification is highly recommended to improve its compatibility with the polymeric matrix. Hence, this paper presents a systematic review of chemically modified cellulose/epoxy resin composites focusing on the last five years. The investigation followed the PRISMA protocol that delivers a meticulous summary of all available primary research in response to a research question. After including/excluding steps, thirty-six studies were included in the review. The results were presented focusing on thermal, mechanical and dynamic-mechanical properties of the composites. In brief, this methodology helped identifying the main gaps in knowledge in that field.
纤维素及其衍生物被广泛探索用于制备薄膜和增稠药物溶液、油漆、复合材料中的增强体等。这种多功能性归因于其可再生性、低成本和环境友好性等优点。当用于聚合物复合材料中时，由于纤维素的亲水性，强烈推荐对其进行表面化学改性，以提高其与聚合物基体的相容性。因此，本文对近年来纤维素/环氧树脂复合材料的化学改性进行了系统综述。该研究遵循 PRISMA 方案，针对研究问题提供了对所有现有原始研究的详细总结。经过包含/排除步骤后，有 36 项研究被纳入综述。结果主要聚焦于复合材料的热、机械和动态机械性能。总之，该方法有助于确定该领域知识的主要缺口。
