Abstract

A method is developed to obtain composite materials from PVDF copolymer (polyvinylidene fluoride/trifluoroethylene having ratio of 94/6) with titanium dioxide particles included in its structure. Using IR spectroscopy, the phase composition of PVDF is estimated for composite materials with different contents of titanium dioxide particles. The crystallinity of the polymer is assessed using DSC analysis. The free surface energy of composite polymer films is estimated using the contact angle analysis for materials having different amounts of included titanium dioxide particles. The electron microscopy technique confirmed that including the titanium dioxide particle affects the surface morphology. Quantitative analysis of included titanium dioxide particles is carried out using thermogravimetric technique. The strategy proposed presents a new approach to obtain and control the phase composition of PVDF-based polymer films.
