| 초록 | A series of poly(vinylidene fluoride) (PVDF)-based composite film with various nano-TiO2 loading values up to 40 wt% were successfully fabricated by a dry-mixing and uniaxial hot-press molding technique. Nano-TiO2 could make the crystal structure of the PVDF α-phase dominant, as characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and differential scanning calorimetry. The homogeneous distribution and interactions of the composites were investigated by scanning electron microscopy and energy-dispersive spectrometry. As the amount of nano-TiO2 increased, the frictional performances was improved owing to the better contact adhesion contributed by the nonpolar α-phase crystal domain of the PVDF. In addition, the incorporation of the nano-TiO2 filler could reduce viscoelastic characteristic of composite film, and as a result, the friction coefficients decreased. Moreover, the taber abrasion resistances were comparable to that of commercial ultra-high-molecular-weight polyethylene (UHMWPE), indicating the availability of PVDF/nano-TiO2 composite film. |
