Preparation of Antibacterial WPU Nanometer Titanium Dioxide Composite

Abstract:

In the paper, WPU nanometer titanium dioxide composite is made mainly of polypropylene glycol (PPG), 2, 4-toluene diisocynate (TDI), nanometer titanium dioxide (TiO2), oleic acid (OA), dimethylolpropionic acid (DMPA), dibutyltin dilaurate (DBTDL), triethylamine (TEA), polypropylene glycol phosphate (PPG-P). Feature of nano particle is analyzed and tested by scanning electron microscope; Fourier infrared spectrum of nanoparticle and composite is tested by fourier infrared spectrometer under room temperature; thermal property test is conducted to composite by thermogravimetric analyzer; XRD test is conducted to nanoparticle and compound thin-film material by X-ray diffractometer; mechanical property of composite is tested by universal stretcher, proving that titanium dioxide does not change structure of WPU and titanium dioxide keeps the original crystal structure instead of being destroyed. Thermogravimetric analysis shows that titanium dioxide raises thermal stability of composite better; mechanical properties prove that increase of 2wt% nanometer titanium dioxide can raise mechanical properties of WPU. Titanium dioxide has extensive application prospect in production and life because it has optical activity and can raise antibiotic property of WPU.
