Summary: | 碩士 === 國立勤益科技大學 === 化工與材料工程系 === 106 === In this research was divided into two parts. Firstly, the titanium dioxide powder needed for the experiment was prepared by sol-gel method. And change the dispersant in the process, and observe the effect of dispersant on titanium dioxide powder. In the second part, the prepared titanium dioxide (TiO2) was added into polyvinylidene fluoride (PVDF), a composite film was prepared by dry phase conversion method, and a composite fiber film was prepared by electrospinning. The thermal properties and mechanical properties were analyzed. , surface morphology and pro/hydrophobic properties.
Through experiments, it has been confirmed that the addition of titanium dioxide improves the hydrophilicity of the composite film, while the thermal stability and mechanical properties of the composite film decrease. The polyvinylidene fluoride/ titanium dioxide composite film prepared by the method enhances the hydrophilicity and increases. Its service life improves the application value of the composite film itself.
