摘要
从静电纺丝射流过程的基本原理出发,结合环境温湿度对同种溶液性能参数和静电纺丝过程中针尖处电荷和介电常数的影响进行理论分析,在现有实验设备的基础上增加了环境温湿度控制系统,通过其实现定温度变湿度、定湿度变温度和综合条件下的低温高湿、中温中湿、高温低湿三组参数进行实验。结果表明,湿度和温度对于静电纺丝过程中针尖之间以及针尖与接收装置之间的挂丝现象和成膜性都有影响,高温低湿的环境可以获得相对稳定且成膜性较好的纤维形貌,而且纤维膜的直径比较均匀,集中在200~350 nm。研究环境温湿度对静电纺丝稳定喷射的影响规律,有助于提高其产业化的可能性。
Starting from the basic principle of electrospinning jet process,combining with the theoretical analysis of the influence of environmental temperature and humidity on the performance parameters of the same solution and the charge and dielectric constant at the tip of the needle in the electrospinning process,the environmental temperature and humidity control systems were added on the basis of the existing experimental equipment.The experiment was carried out in the conditions of constant temperature and humidity and comprehensive conditions of low temperature and high humidity,medium temperature and humidity,high temperature and low humidity.The results show that the humidity and temperature have effects on the phenomenon of hanging and film forming between the tips and between the tips and the receiving device.In the environment of high temperature and low humidity,a relatively stable and film forming fiber morphology can be obtained,and the diameter of the fiber film is relatively uniform,concentrated 200-350 nm.The research on the influence of environmental temperature and humidity on the stable jet of electrospinning is helpful to improve the possibility of its industrialization.
