Superparamagnetic wood‐polypropylene nanocomposite made using magnetic wood flour with a nanoparticle‐free surface

Abstract

This study investigates the effect of removing magnetic nanoparticles from the outer surface of magnetic wood flour (MWF) particles as a filler phase on the microstructural, physical, and mechanical properties of the prepared MWFpolypropylene nanocomposites. For producing MWF with a surface free of magnetic nanoparticles (called LFMWF), in contrast to the commonly produced MWF (called FFMWF), magnetic wood chips were first prepared and then milled. No significant changes were observed in the tensile and flexural strength of the composite specimens prepared with the LFMWF filler instead

Composite of Poly(Vinyl Chloride) Plastisol and Wood Flour as a Potential Coating Material

“…Various traditional thermoplastics such as polythene, polypropylene, acrylonitrilebutadiene-styrene copolymers, polyamide, polystyrene, poly(methyl methacrylate), poly(vinyl acetate), and polycarbonate were used as matrixes of polymer-wood composites [3][4][5][6][7][8][9][10]. These materials were also manufactured using thermosetting plastics like epoxy, polyurethane, and phenolic resin [11][12][13][14][15][16].…”

“…The wood material came from both deciduous and coniferous trees [6,[15][16][17]. Fillers were used in their original form and after preliminary modification, which may include the removal of lignin, coating with magnetic particles, attachment of epoxy and methacrylate groups, and even modifications using ionising radiation [4,5,7,11,13,14]. The main characteristics of the composites, regardless of the matrix The plastisol consisted of 900 g of powdered PVC polymer, 1080 g of ADO plasticiser, and 18 g of MARK-17 MOK stabiliser.…”
