In a method for making a flexible material, a sheet of graphene oxide-composite paper is subjected to an environment having a relative humidity above a predetermined threshold for a predetermined amount of time. At least one expansion cut is cut in the sheet of graphene oxide-composite paper. A flexible conductive material includes a sheet of graphene oxide-composite paper defining at least one cut passing therethrough and formed it a kirigami structure. A region of the sheet of graphene oxide-composite paper includes reduced graphene oxide.

A leather substrate formed from waste leather and its method of production, particularly a leather substrate made up substantially of a collagen fibril matrix.

An absorbent composite foam is provided having a density below 0.04 g/cc and low wet collapse comprising (i) between about 5 to about 40% by wt. fluid resistant fibers; (ii) between about 30 to about 80% by wt. cellulosic fibers; (iii) between about 5 to about 35% by wt. binder; and (iv) a foaming surfactant. The combination of ultra-low density and wet stability is achieved, despite a high proportion of cellulosic fibers, by having both hydrogen bonding between cellulosic fibers as well as inter-fiber bonds formed by the binder.

An artificial leather is provided in some embodiments of the present disclosure, including: an artificial bio-nutritional fiber layer and a mycelium layer. The artificial bio-nutritional fiber layer includes a first surface, a second surface opposite to the first surface and a plurality of holes, in which the plurality of holes extends from the first surface to the second surface. The mycelium layer encapsulates the first surface and the second surface of the artificial bio-nutritional fiber layer, and extends from the first surface to the second surface through the plurality of holes. A manufacture method of an artificial leather is further provided in some embodiments of the present disclosure.
