Anti-fungal activity of rutin and rutin-metal complexes as wood protectants
2017 - IRG/WP 17-30708
The anti-fungal activity of Rutin, a flavonoid, alone or complexed with copper or zinc was investigated in a petri dish test with Gloeophyllum trabeum and Trametes versicolor as the test fungi. Rutin and the Rutin-metal complexes showed significant inhibition against each fungus. Rutin-Cu and Rutin-Zn strongly inhibited the brown rot fungus, G. trabeum, while Rutin and Rutin-Zn inhibited T. versic...

Permeability of Eucalyptus wood improved by microwave treatment
2017 - IRG/WP 17-40773
The wood species with low permeability may cause many problems during timber manufacturing. Extreme difficulties take place in fabricating new wood-based composites by impregnating low- permeability timber with functional materials, such as flame retardant, preservatives and resins. Microwave (MW) treatment can increase the permeability of wood both in transverse and longitudinal directions. The e...

Controlled deposition of copper nanoparticles using wood inherent architecture as natural template
2017 - IRG/WP 17-40783
As one of the most abundant renewable biomass resources, wood can be used as templates for synthesizing functional nanoparticles with controlled shapes and sizes. In this study, copper nanoparticles were synthesized with controlled shapes and sizes using poplar wood as the natural inexpensive and renewable templates. The crystal structure and morphologies of the copper nanoparticles were character...

Multiscale modification on water resistance and dimensional stability of Populus cathayana by alkali lignin combined with heat treatment
2018 - IRG/WP 18-40826
The aim of this study was to enhance the water resistance and dimensional stability of fast growing wood by alkali lignin combined with heat treatment. Poplar (Populus cathayana) samples were first impregnated with alkali lignin solution and then subjected to heat treatment at 140, 160, and 180°C respectively for 2h. Properties of leachability, moisture adsorption and water absorption, contact an...

Facile in-situ growth of Ag-TiO2 nanoparticles on polydopamine modified bamboo with excellent mildew-proofing
2019 - IRG/WP 19-30734
Bamboo with good mechanical properties, fast growth rate and low growth cost is one of very utilitarian structural material from forest resources only less important than wood. But it is especially easy to mildew during outdoor service resulting in appearance mould scattering and corrosion. In this work, a facile method was developed to increased mildew-proofinging capability of bamboo. Mussel-ins...

Wood veneer with high flexible decorated with nanoparticles for highly efficient water treatment
2019 - IRG/WP 19-50347
Natural wood is mainly comprised of numerous long, partially aligned channels (lumens) as well as nanochannels. Wood with these quick and effective passages is suitable for a membrane/separation material. However, a suitable thickness range of wood along its growth direction is essential to effectively separate small molecular, and the wood membrane is too thick to clean easily. In this paper, woo...
