Claim Text:
1. A fibrous mesh of thermal-mechanically annealed cellulose that is subsequently oxidized and sulfated, wherein the thermal-mechanical annealing is performed under a pressure in the range from about 10 MPa to about 500 MPa and at a temperature from about 60° C. to about 240° C.; and wherein the fibrous mesh have thicknesses from about 10 μm to about 500 μm and comprise fibers from about 100 nm to about 20 μm in fiber diameter; the fibrous mesh comprises fibers having a tensile elastic modulus from 2 MPa to 20 MPa and an ultimate tensile strength from 50 KPa to 1.0 MPa.
