Principle of non-solution contact electrospinning

通过自行设计的逆向电场静电纺丝装置和非溶液接触式静电纺丝装置,进行了一系列静电纺丝实验,并采用ANSYS有限元分析软件对前述静电纺丝装置的场强分布进行了模拟与分析,分别从理论和实践上论证了非溶液接触式静电纺丝技术的可行性.研究结果表明:采用此种非溶液接触式静电纺丝技术,同样可以得到纳微米纤维,且直径分布均匀,无溶剂残留,纤维形貌与传统静电纺丝技术基本一致,且安全性极佳,可望用来实现纳米纤维的工业化生产.

Self-designed reverse electric field electrospinning device and non-solution contact electrospinning device were employed to carry out a series of electrospinning experiments, and ANSYS finite element analysis software was used to simulate and analyze the field intensity distributions of the electrospinning setups, and thus to demonstrate the feasibility of non-solution contact electrostatic spinning technology theoretically and practically. The research results showed that, by using non-solution contact electrospinning technology, the nanofibers with narrow diameter distribution can also be obtained and no residual solvent, meanwhile the morphology of the nanofibers were same to that from conventional electrospinning technology, and the former has excellent safety property, which is expected to realize the production of nanofibers at industrial scale.
