Transparent wood is an attractive material, attracting a lot of attention from
the scientific community in recent years due to its potential applications in
construction, interior and decorative materials. Compared with common
wood, transparent wood has many improved mechanical properties such
as mechanical strength, water uptake. Transparent wood is generally
presumed to be inherently more resistant to moisture uptake than solid
wood. In addition, wood-plastic composite is biodegradable, so it is more
environmentally friendly. This paper presents a simple chemical treatment
of Styrax tonkinensiswood in two stages with sulfate agents (NaOH + Na2
S)
and with (CH
3COOH+H2O2
). Bleached wood samples were determined for
lignin content to determine the efficiency of the lignin removal process and
morphological analysis by SEM images. Studying the chemical treatment
of wood will advance insights into chemical treatment wood, making it
possible to deploy on a larger scale than the laboratory scale
