摘要
为制备超疏水聚乳酸吸油材料,研究分析了目前使用较多的聚乳酸超疏水改性的方法,结果表明:静电纺丝法降低了纤维的细度,提高了聚乳酸纤维膜的疏水性,达到了超疏水性,但由于其较低的工艺生产量和高电压的安全隐患,商业化应用受到了限制。相分离法通过溶剂挥发两相分离,最终获得聚乳酸超疏水表面,利用该方法可以控制材料孔径而改变材料性能,但制备工艺条件苛刻,批量化生产难度大。涂层法可以形成均匀的涂层,操作简便,设备简单,适合于大规模批量生产,也可用于实验室,但部分溶剂会对环境产生一定的污染。
In order to prepare superhydrophobic PLA oil absorbing materials,the methods of superhydrophobic modification of PLA were studied and analyzed.The method of electrospinning greatly reduced the fitness of fiber,improved the hydrophobicity of PLA fiber membrane,and most of them were superhydrophobic.However,due to its low production capacity and high voltage safety hazards,the commercialization of this method was limited.The superhydrophobic surface of PLA was obtained through the two-phase separation of solvent volatilization.Using the phase separation method,the material pore diameter could be directly controlled to change the material performance,but the preparation process condition was harsh,the operation was complex,and the batch production was difficult.The coating method could form uniform coating,which was easy to operate.It was suitable for mass production and laboratory,but some solvents would pollute the environment.
