Vaseline gauze is a common type of wound dressing that consist of absorbent gauze impregnated with white

petrolatum. It has excellent anti-adhesive property which can reduce trauma during dressing changes. However,

this kind of wound dressing doesn’t have bacterial killing property. Thus, a new kind of wound dressing that has

anti-adhesive and bactericidal properties is needed urgently. Creating slippery liquid-impregnated porous surfaces

(SLIPS) that insensitive to the structure of porous solid are generally viewed as a new anti-adhesion

strategy. To expand the potential utility of SLIPS as substitute for vaseline gauze, dual-functional slippery

membranes with anti-adhesion and bactericidal properties by using triclosan, vegetable oils and polylactic acid

(PLA) were prepared. It’s demonstrated that the triclosan-loaded/vegetable oils-infused PLA membranes (T/VPM)

has good cytocompatibility in vitro. Notably, the T/V-PM can gradually release biocide molecule into surrounding

aqueous media. Moreover, the T/V-PM can kill planktonic bacterial cells without loss of their antifouling

property. The in vivo study revealed that the T/V-PM can prevent the secondary injuries during wound

dressing changes. This simple and low-cost strategy can be applied to inhibit blood and bacterial adhesion, and

prevent tissue adhesion at the wound site. It’s confirmed that the T/V-PM have great potential as substitute for

vaseline gauze.
