Abstract:The focus of this research is on wood coatings made from this `woody thermoplastic' material, as it could provide a greener substitute to common synthetic paints and coatings. The use on natural substrates like wood again allows for fully recyclable end products. A primitive paint is made by dissolving the polymer in acetone. The paint is then brushed on plywood to form coating samples for further testing. The thermal properties of the material are measured, and the coating is tested on hydrophobicity, surface roughness, and weather resistance. The change in properties due to weathering is also monitored. Unfortunately, the coating properties quickly deteriorate when exposed to the outdoors, as found in the natural weathering test. UV exposure is suspected to be the main cause of degradation and is therefore briefly discussed as a topic for future work. To be useful as coating material, the material would have to be improved in strength and a proper paint may need to be formulated to improve the coating durability and resistance against degradation.
