摘要
Abstract
The CS/PVP nanofibrous membrane was prepared by electrospinning .Various blends of CS/PVP solutions including 0/100、10/90、20/80、30/70、40/60 were formed.The nanofibrous membrane is characterized by SEM,FTIR,X-ray diffraction,the breaking strength of the membrane was tested by u-sing electronic strength tester.The results show that,when CS/PVP changes to the mass ratio of from 0/100 to 30/70,fiber morphology is good,the content of CS increases while the average diameter gradu-ally decreases.When the mass ratio reaches 40/60,there is a large number of beads inside the fiber and its uniformity deteriorates.FT-IR and X-ray diffraction spectra indicate that there is interaction between PVP and CS in the nanofibrous membrane and the molecules themselves form hydrogen bonds.The breaking strength of the nanofibrous membrane increases with the content of CS,when the content of CS reaches 40%,the breaking strength is 19.87 MPa.关键词
