Physical, and Thermal Properties of Wood Impregnated with a Mixture of Furfuryl Alcohol, Styrene, and Nanoclay

Abstract

In this study, raw wood (RW) samples were impregnated with a mixture of furfural alcohol (FA), styrene (ST), and nanoclay of varying concentration of FA and ST. These impregnated wood and RWsamples were then subjected to FTIR, water uptake (WU), and thermal studies. The FT-IR results at 1600-1800 cm-1 showed that the ST/FA/clay-WPNCs had different peak numbers with different positions compared with the RW. So, there was an interaction between RW, FA, ST and clay. The WU of ST/FA/clayimpregnated wood is lower than RW. In thermo gravematric result, below 100 °C the impregnated wood samples had less weight lost compared to RW.

Modification of wood with copolymers based on glycidyl methacrylate and alkyl methacrylates for imparting superhydrophobic properties

“…Previous studies describe a wide variety of wood modification methods that allow to impart protective properties including water repellency; these approaches include enzymatic modification, 12 heat treatment, 13 corona discharge treatment and plasma‐arc machining, 14,15 glow discharge cold plasma treatment, 16 mercerization, 17 acylation and silylation, 18–20 furfurylation, 21 treatment with anhydrides, 22 resins and oils, 23,24 and modification with polymers (e.g., poly[ethylene glycol], 25 glycerol‐based polymers 26 ). However, current studies provide insufficient information on the modification of wood with polymers despite the prospects of this approach for improving various properties 27 such as reducing abrasion, increasing the service life of wood, 28 improving the strength characteristics towards all types of mechanical stress, adhesion of coatings 11,29 and resistance to attack by corrosive media, water repellency, and waterproofness 30,31 .…”
