本研究旨在开发接枝纤维素纤维基材料（聚乙烯蜡-接枝马来酸酐）/纤维素纤维；皮尤- g - MA/CF)对水溶液中油脂的有效吸收。通过纤维素纤维与马来酸酐改性聚乙烯蜡的接枝改性制备了PEW - g - MA/CF，为纤维素基高吸油剂的合成提供了一种经济有效的方法。采用傅里叶变换红外光谱、原子力显微镜和热重法对制备的皮尤- g - MA/CF进行了系统表征；对原料质量比、反应温度、反应时间等因素对吸油性能的影响进行了研究和比较。在重量比为1:1的条件下，最大吸油量可达19.36 g/g‐1；温度60°C;总的来说，PEW - g - MA/CF是一种环境友好且具有高吸收率的水溶液材料，该有价值的发现可能为最大化纤维素基吸附剂在各种应用中的潜力提供了一种思路。
The work reported aims to developing the grafted cellulose fiber‐based material (polyethylene wax‐grafted maleic anhydride)/cellulose fiber; PEW‐g‐MA/CF) for efficient absorption of oil from aqueous solution. PEW‐g‐MA/CF was prepared via grafting modification between cellulose fiber and the maleic anhydride modified polyethylene wax, resulting in a cost‐effective approach for synthesizing cellulose‐based oil super absorbent. The as‐prepared PEW‐g‐MA/CF was systematically characterized via Fourier‐transform infrared, atomic force microscope, and thermogravimetric; the influencing factors of oil absorption, including the weight ratio of the raw materials, reaction temperature, and reaction time, were studied and compared. The maximum oil absorbency was up to 19.36 g/g‐1with the condition of weight ratio 1:1; temperature 60°C; and reaction time 3 h. Overall, PEW‐g‐MA/CF is an environmentally friendly and cost‐effective material for high oil absorption from aqueous solution, and the valuable findings might provide an idea for maximizing the potential of the cellulose‐based absorbents for a variety of applications.
