First claim
Opening claim text (preview).
What is claimed is: 1 . A water-based method for making a plant fiber biocomposite comprising a network of lignin-containing plant fibers crosslinked by a polymer, said method comprising contacting said lignin-containing plant fiber with the polymer in water at a pH of from about 0 to about 5 to crosslink said lignin-containing plant fiber to said polymer. 2 . The method of claim 1 , wherein said lignin-containing plant fiber is selected from the group consisting of a hemp fiber, a flax fiber, a jute fiber, a sisal fiber, a kenaf fiber, a coconut husk fiber, and a coco coir fiber. 3 . The method of claim 1 , wherein said contacting comprises a temperature of from about 60° C. to about 100° C. 4 . The method of claim 1 , wherein said method is performed without producing formaldehyde, methylene chloride, or methanol. 5 . The method of claim 1 , wherein the polymer comprises pectin or polyvinyl alcohol (PVA).
