Abstract:

A strong, transparent cellulose material was prepared by a two-step method(delignification and pressure drying). The obtained cellulose material not only exhibited a highest transmittance of 68%(600 nm) and a transmission haze of 95%, but also has a maximum tensile strength of 362 MPa and an elastic modulus of 9.5 GPa. Scanning electron microscope(SEM), X-ray diffraction(XRD), thermal gravimetric analyzer(TGA), ultraviolet-visible(UV-Vis) spectrophotometer, and tensile tester were applied to analyze the structure, mechanical and optical properties, thermal stability, and crystallinity of cellulose material. and the underlying principles for the optical transparency and strong tensile strength of the cellulose material was confirmed based on above characterizations.

Key words: Strong tensile strength and transparency, Cellulose material, Aligned structure, Fir wood, Delignification, Mechanical property
