Development of wearable triboelectric Nanogenerators using optimised knitted structures

Abstract

Wood is a versatile and widely utilized material in various industries, ranging from construction to furniture manufacturing. In the context of the wood industry in Sri Lanka, The uses of wood in Sri Lanka date back to ancient times, with evidence of woodworking found in archaeological sites. This research aims to shed light on the intricate dynamics involved in the preservation and enhancement of wood quality by considering the specific effect of wood moisture content before dip diffusion treatment. This research conducted the quantitative industrial survey of mid-scale wood companies and qualitative testing procedures using Pine (Pinus), Hawarinuga (Alstonia), Mahogany (Swietenia), Mango (Mangifera indica), and Rubberwood (Hevea brasiliensis) types treated with two types of organic wood preservatives namely FSWOM, FSWM, and two types of industrial wood preservatives namely boron based treatment and ACQ.the wood samples tested with different moisture content level during six week. The study determined the recommended moisture content ranges for the selected wood preservative types and wood types. Pine wood can be recommended for FSWOM, FSWM, ACQ and Boron at 18% to 22 %. And considering Alastonia wood can only recommend FSWM moisture content range of 26 % to 30 %. consider the Mahogany wood can only recommended FSWM moisture content range of 24 % to 28 %. Also, Mango wood can recommended FSWOM moisture content range is 16 % to 26 %, FSWM is 16 % to 28 %, ACQ is 18 % to 28 % and Boron is 16 % to 22 % for Mango wood. Finally, Rubberwood moisture content is recommended as FSWOM moisture content range is 14 % to 17 %, FSWM is 14 % to 18 %, ACQ is 15 % to 18 % and Boron is 15 % to 18 %. Alstonia and Mahogany null hypothesis accepted. Can not recommend moisture ranges for FSWOM, ACQ and Boron. It would affect other factors to the Alstonia wood preservatives uptake. The study confirms the moisture content significantly affects the uptake of preservatives during wood treatment. The experimental findings indicate that preservative uptake is limited by the moisture content present in the wood.
