Wood polymer composites (WPC) are sensitive to moisture because of the hydrophilic nature wood fibers. The main objective this study was improve dimensional stability WPCs by coating. Polypropylene and polylactic acid were reinforced three pulp fibers (kraft, thermomechanical (TMP), chemothermomechanical (CTMP)) at fiber contents (50, 60, 70% w/w). resulting coated using two commercial coatings...

New highly hydrophobic fluorinated oligoamides were synthesized and studied as materials for the protection of non-varnishable wooden artifacts. The new designed to achieve best performance (including high chemical affinity wood material) lowest environmental impact. In order minimize risk bioaccumulation, short perfluoroalkyl side chains reacted with oligoethylene L-tartaramide (ET), adipamide...

This study examined the physiological effects of touching wood with various coating with the palm of the hand on brain activity and autonomic nervous activity. Participants were 18 female university students (mean age, 21.7 ± 1.6 years). As an indicator of brain activity, oxyhemoglobin concentrations were measured in the left and right prefrontal cortices using near-infrared time-resolved spect...
