本研究的目的是生产柔性、阻燃、防水和可生物降解的复合材料。本研究的最终目标是开发简单的工艺，用于生产能够取代印刷电路板中不可降解基材的生物基材料。选择可再生资源纤维素，将其溶解于1-乙基-3-甲基咪唑乙酸盐离子液体中，制备纤维素连续膜。由于阻燃性是电子设备应用的重要标准，而纤维素是天然易燃的，因此我们将聚磷酸铵（APP）作为阻燃填料加入，以提高生产材料的阻燃性。开发的材料在可燃性测试中达到了UL-94 HB评级，而不含APP的纤维素样品未通过测试。两种疏水剂，2-氰基丙烯酸乙酯和三氯（十八烷基）硅烷施加通过一个简单的浸涂技术赋予纤维素-APP复合材料的疏水性。动态力学分析表明，纤维素材料的力学性能没有显着影响的APP或疏水剂的添加。此外，由于纤维素酶的存在，含有APP的纤维素材料的生物降解性增加。疏水涂层使纤维素-APP的生物降解性略有下降，但仍高于纯纤维素膜。
The aim of the present study is to produce flexible, flame-retardant, water-resistant and biodegradable composite materials. The ultimate goal of this research is to develop simple processes for the production of bio-based materials capable of replacing non-degradable substrates in printed circuit board. Cellulose was chosen as a renewable resource, and dissolved in 1-ethyl-3-methylimidazolium acetate ionic liquid to prepare a cellulosic continuous film. Since flame retardancy is an important criterion for electronic device applications and cellulose is naturally flammable, we incorporated ammonium polyphosphate (APP) as a flame-retardant filler to increase the flame retardancy of the produced materials. The developed material achieved a UL-94 HB rating in the flammability test, while the cellulose sample without APP failed the test. Two hydrophobic agents, ethyl 2-cyanoacrylate and trichloro(octadecyl)silane were applied by a simple dip-coating technique to impart hydrophobicity to the cellulose-APP composites. Dynamic mechanical analysis indicated that the mechanical properties of the cellulosic materials were not significantly affected by the addition of APP or the hydrophobic agents. Moreover, the biodegradability of the cellulosic materials containing APP increased owing to the presence of the cellulase enzyme. The hydrophobic coating slightly decreased the biodegradability of cellulose-APP, but it was still higher than that of pure cellulose film.
