Abstract

The papermaking industry nowadays mainly made from softwood and hardwood causes many trees are cut down and tends to lose a main resource of forest. An alternative solution is made by using the biomass waste from natural resources like durian shell is used as the raw material in producing variety type grades of paper. This alternative way has potential in producing a biodegradable product that can easily decompose and contribute to the sustainable development. However, the properties of existing paper that are easily to absorb water, and also low in mechanical properties made the paper has low quality and limited in application. Thus, in this study, durian shell is used as the main raw material with the aim to make a superhydrophobic surface of green magnetic sheet. Three techniques of fabricating superhydrophobic surface which are dip coating using stearic acid, blending polymer via disintegration technique, and drop-coating the mixed solution comprising of modified silica particles and polystyrene (PS) emulsion are applied to the green magnetic sheet. Then, the green magnetic sheets are characterized in term of surface morphology and water absorption. The best potential technique of dip coating using stearic acid has been selected due to the achievement of superhydrophobic water contact angle that exceed 150o, with the acceptable mechanical properties of tensile index (4.7133 Nm/g) and tear index value (3.0476 m.Nm2/g). By forming superhydrophobic surface of green magnetic sheet, this research contributes in future for the application of wallpaper that has ability to absorb sound or wave energy with the specialty characteristic of waterproof. Thus, the waterproof wallpaper can be used in variety environment, including moist environment and directly act as a sustainable product that minimize environmental impact on the future generation .
