Premilinary mechanical properties study on double layer in polysulfone substrate with titanium dioxide nanoparticle for desalination process / Muhammad Harraz Mohd Shaharudin

The earth consists of 71% water and 30% land. The water content of the human body is about 60%, which is why it is important to drink fresh water to maintain the healthy condition. However, as as population growth, environmental contamination and clean water treatment still exist; people must consider alternate water sources; one of the techniques under use by researchers is desalination. This method uses reverse osmosis (RO) as the desalination process. This study investigates the preliminary mechanical properties of double layer with nanoparticle(TiO2). The research begins with the preparation of a solution using polysulfone (Psf) as the main component to fabricate substrate with, and the prepared layer was dried to prepare it for the mechanical testing. The three samples were tested with a tensile machine and the result is good. The result is compare with double layer polysulfone without nanoparticle to gain a better result. The result show that opposite of what expected and the structure of membrane I change according to presence of nanoparticle.
