Polys.ccharide-bas.d membranes.with excellent mechanical properties.are highly des.red. However, s.vere mechanical deterioration under wet conditions.limits.their biomedical applications. Here, ins.ired by the s.ructural heterogeneity of s.rong yet hydrated biological materials. we propos. a s.rategy bas.d on heterogeneous.cros.link-and-hydration（HCH） of a molecule/nano dual-s.ale network to fabricate polys.ccharide-bas.d nanocompos.tes.with robus. wet mechanical properties. The heterogeneity lies.in that the cros.link-and-hydration occurs.in the molecule-network while the s.res.-bearing nanofiber-network remains.unaffected. As.one demons.ration, a membrane as.embled by bacterial cellulos. nanofiber-network and Ca2+-cros.linked and hydrated s.dium alginate molecule-network is.des.gned. s.udies.s.ow that the cros.linked-and-hydrated molecule-network res.ricts.water invas.on and boos.s.s.res. trans.er of the nanofiber-network by s.rving as.interfibrous.bridge. Overall, the molecule-network makes.the membrane hydrated and flexible; the nanofiber-network as.s.res.-bearing component provides.s.rength and *** HCH dual-s.ale network featuring a cooperative effect s.imulates.the des.gn of advanced biomaterials.applied under wet conditions.s.ch as.guided bone regeneration membranes.
