Abstract
Initially, WPC was formulated using extrusion technique
through different percentages of wood flour (WF) with virgin
polyethylene (PE) in presence of a coupling agent. The optimized
formula was subjected to surface treatment by different methods
including chromic acid oxidation, Ultraviolet (UV) irradiation,
flame and heat treatment. Then the treated surface of WPC was
coated with nano-modified epoxy resin using carboxylated carbon
nanotube (CNT-COOH), organically modified nanoclay (Cloisite30B) and Reactive Rubber Nano Particle (RRNP).
The adhesion strength of the nano-modified epoxy showed
significant enhancement when investigated by pull-off method and
the cross-cut test. Nano-scratching was utilized in exploring the
effect of different surface treatments on enhancing adhesion of
epoxy to WPC. The results indicated that chemical treatments
helped for functionalization of the WPC surface leading to stronger
adhesion with nano-modified epoxy. Thermal analysis indicate.
