Luffa cylindrica is primarily used as a vegetable, but its dry fiber can be also used as a sponge. L. cylindrica has a ligneous fibrous netting system, in which the fibrous cords are disposed in a multidirectional array, forming a natural mat. In this work, we aim to synthesize a potential material for oil spill cleanup by the graft polymerization of butyl acrylate (BA) onto Luffa fiber (LF) using 2,2′-azobisisobutyronitrile (AIBN) as initiator. The grafting process has been controlled by monomer and AIBN concentrations, reaction time and temperature, in which the optimal condition for the highest graft yield of 40.60% is [AIBN] = 0.035 mol/L, [BA] = 1.50 mol/L, 180 min at 75 °C. The graft copolymer LF-g-BA is structurally characterized by the Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction. In the presence of crosslinking agent divinyl benzene, the oil sorption capacity of the synthetic LF-g-BA reaches 20.60 g oil/g sorbent for 48-h treatment. The LF-g-BA material can be seen as a potential sorbent due to its swelling property in non/weak polar mediums and reusable feature.

丝瓜主要用作蔬菜，但其干纤维也可用作海绵。L. cylindrica具有木质纤维网系统，其中纤维绳以多向阵列布置，形成天然垫。在这项工作中，我们的目标是通过使用 2,2'-偶氮二异丁腈 (AIBN) 作为引发剂将丙烯酸丁酯 (BA) 接枝聚合到丝瓜纤维 (LF)上来合成一种潜在的溢油清理材料。接枝过程受到单体和 AIBN 浓度、反应时间和温度的控制，其中最高接枝率为 40.60% 的最佳条件是 [AIBN] = 0.035 mol/L, [BA] = 1.50 mol/L, 180在 75°C 下分钟。接枝共聚物LF- g-BA 的结构特征在于傅里叶变换红外光谱、扫描电子显微镜和 X 射线衍射。在交联剂二乙烯基苯存在下，合成 LF- g- BA的吸油能力达到 20.60 g 油/g 吸附剂处理 48 小时。由于 LF- g- BA 材料在非/弱极性介质中的溶胀特性和可重复使用的特性，它可以被视为一种潜在的吸附剂。
