Transparent wood prepared by polymer impregnation of rubber wood (Hevea brasiliensis Muell. Arg)

Transparent wood (TW), a new type of composite material with good optical transmittance and excellent mechanical properties, has attracted great interest in recent years. In this study, hydrogen peroxide strategy was used on rubber (Hevea brasiliensis Muell. Arg) to eliminate lignin hemicellulose. Subsequently, delignified combined each three impregnants refractive index similar that cellulose obtain transparent (TW). Impregnation polyvinyl-pyrrolidone (PVP), polyvinyl alcohol (PVOH), methyl methacrylate (MMA)) resulted woods, which were named PVP-DRW, PVOH-DRW, PMMA-DRW, respectively. The micromorphologies, chemical compositions, thermal stabilities, functional groups, transmittance, properties the raw RW processed sample characterized. results showed PVOH-DRW (76.6%, λ = 600 nm, d=0.70 mm) PVP-DRW (73.4%, d 0.74 higher than PMMA-DRW (64.6%, 0.73 mm), but had strength (fracture 230.14 MPa). Therefore, preparation as substrate is expected be potential candidate for high-strength composites.
