This research aims to study the preparation of Nano-particle film about the process of titanium dioxide by to park and prungonuphak Nano titanium dioxide with the heat from the laser beam. Heat and light oven baking, and then study the results of how the heat properties of films include: The physical characteristics of the film by atomic force microscope electron microscope the songkrat. Surface wetting properties by measuring angles, touching the water droplets. Finance and properties properties fo Toh Lim TA. cache machine UV-spectrometer and Reuben boen element chemistry of film by Raja Maan spectrometer. Also, there is a range of testing with simulated rainfall films.
