The present invention provides interpenetrating polymeric networks (IPNs), and related methods and compositions. The hydrogel material of this invention comprises an interpenetrating network of two or more polymer networks, wherein at least one of the polymer networks is based on a biopolymer. Also provided is a method of producing the hydrogel material comprising, combining a first polymeric network with a second polymeric network, wherein the first polymeric network or the second polymeric network is based on a biopolymer. The present application also discloses devices manufactured from the IPN hydrogel material and uses thereof.
L'invention concerne des alliages IPN (réseaux polymères interpénétrés), et des procédés et compositions associés. Le matériau hydrogel de l'invention comprend un alliage IPN d'au moins deux réseaux polymères, au moins un des réseaux polymères étant à base d'un biopolymère. L'invention concerne également un procédé de production d'un matériau hydrogel qui consiste à mélanger un premier réseau polymère à un deuxième réseau polymère, le premier réseau polymère ou le deuxième réseau polymère étant à base d'un biopolymère. L'invention concerne également des dispositifs fabriqués à partir du matériau hydrogel IPN et des utilisations de ceux-ci.
