A method of reversible swelling and collapsing of the latent pores of natural fiber welded biopolymer by way of sequential solvent treatment to i) regenerate mesoporous biopolymeric structures, comprising the steps of providing a nonporous natural fiber welded biopolymer composite, submerging the nonporous composite in polar solvent, exchanging submersion solvents, typically starting from a solvent of polar identity and ending with a solvent of nonpolar identity, then removing the solvent; and ii) regenerate nonporous biopolymeric structures, comprising the steps of providing a mesoporous natural fiber welded biopolymer composite, submerging the mesoporous composite in polar solvent, then removing the solvent. A mesoporous biopolymeric structure wherein the NFW nonporous composite expresses a BET surface area change of <5 m2 g−1 to >40 m2 g−1. A nonporous biopolymeric structure wherein the NFW mesoporous composite expresses a BET surface area change of >40 m2 g−1 to <5 m2 g−1.
