Abstract: Multifunctional mulberry silk fabrics with excellent temperature- and pH-sensitivity,
antibacterial properties and permeability are successfully prepared by surface modification with
PNIPAAm/chitosan/poly(ethylene oxide) nanofibers. The nanofibers deposited on the surface
of mulberry silk fabric are produced by the electrospinning technique. The surface properties of
mulberry silk fabrics were changed by coating process and glutaraldehyde vapor cross-linking
technology. The PNIPAAm/chitosan/PEO nanofibers have good apparent morphology and uniform
fiber diameter. The contact angle of modified mulberry silk obviously increases with the increasing
temperature. The bacterial reduction rates of modification of mulberry silk against E. coli and
S. aureus all reach above 80%.
