Abstract
A hydrogel structure comprising: (a) a one way penetrating polyurethane film layer; (b) a hydrophobic pressure sensitive adhesive layer; (c) a multi-directional elastic meltblown nonwoven; (d) an interpenetrating polymer network; and (e) a hydrogel; wherein the meltblown nonwoven and the hydrogel are laminated by UV curing to form the interpenetrating polymer network, part of fibers of the meltblown nonwoven are exposed and fit stably with the pressure sensitive adhesive film. The hydrogel structure can make dressings multi-directional elastic for multiple traumas. The hydrogel structure can provide an environment suitable for wound healing, shorten the healing time, antiseptic and reduce the chances of being infected for the wound dressing.
