Abstract
Poly(vinilydene fluoride) (PVDF) homopolymers, whose main chain is formed by the repetition of –(CF2–CH2)n – monomers, are used in a diverse range of industries where their unique set of properties which includes high purity and chemical resistance abrasion resistance, fire resistance, weatherability to UV and humidity, mechanical strength, flexibility, impact resistance, thermal stability, and ease of processing, is required. Nanoparticles with their nanometer size, high surface area, and the associated performance of interfaces can be used as structure and morphology directors in the nanocomposites production. Incorporation of nanoparticles into various polymers to produce composites has been extensively utilized in an attempt to enhance the mechanical, physical, and thermal properties of polymer. In recent years, some investigations have been pursued on of PVDF/nanoparticle composites, which main motivation is related to the control of the crystalline phase, thereby conferring to the resulted material desirable features. For this work nanocomposite of Poly(vinylidene fluoride) (PVDF) was prepared with graphene oxide (GO) and multi-walled carbon nanotubes (MWCNTs) by solution method. That work focuses on UV-Vis and FTIR spectroscopy as methods currently used in the characterization of composites based on carbon nanoestructures in fluorpolymers matrix. The contribuition of UV-Vis and FTIR spectroscopy to establish the type of interaction between the two constituents will be discussed for PVDF/GO and PVDF/MWCNTs.
