Five spinning solutions with different concentrations were prepared using ethyl cellulose as the raw material,and five kinds of ethyl cellulose nanofiber membranes (Samples 1#,2#,3#,4#,and 5#) were subsequently fabricated through electrospinning technology.The surface morphology,crystalline structure,reversible strain and contact angle of five samples were tested and characterized,respectively.The results showed that all samples possessed oriented structure and exhibited hydrophobicity.The crystallinity of the nanofiber membranes gradually increased with the increase of the concentration of the spinning solution.By choosing the amorphous region as the driving phase and the crystalline region as the fixed phase,the reversible shape memory effect was successfully imparted to the nanofiber membranes.The reversible strain of the five samples during the cyclic temperature change process was tested by a dynamic mechanical thermal analyzer,which also indicated that the nanofiber membranes with reversible shape memory effect were successfully prepared by electrospinning technology.This material has broad application prospects in the field of smart textiles.
