A Brief Review on Nanocomposites based on PVDF with Nanostructured TiO2 as Filler

Abstract

Nanocomposites are based on a combination of two or more nanomaterials. Depending on the selection of the constituents forming the composite, the end properties may be tuned as per requirements. Moreover, the combination of organic and inorganic materials can help improve the composite properties a step further, and thus provide exceptional functionalities. Owing to their exceptional mechanical and thermal stability, titania (TiO 2 ) nanostructures are one of the most commonly used reinforcements. Thus, considerable research has focused on the development and characterization of TiO 2 reinforced composites based on several different polymer matrices. Amongst the matrix materials used in different nanocomposites, Polyvinylidene Fluoride (PVDF) is the choicest matrix because of its stability, ease of processing and good mechanical properties relative to other thermoplastic polymers. This review focuses on recent progress in the incorporation of TiO 2 nanostructures into a PVDF matrix so as to develop nanocomposites having outstanding optical, mechanical and electrical properties. A summary of the diverse potential applications of the PVDF/TiO 2 nanocomposites has also been given.

Utilizing multicriteria decision‐making approach for material selection in hybrid polymer nanocomposites for energy‐harvesting applications

“…TiO 2 addition enhances PVDF's mechanical and electrical properties. [19][20][21] In addition, the ceramic fillers occupy more than 50% volume of the polymer matrix, resulting in high dielectric strength and piezoelectric properties. 22 Furthermore, adding a conductive nanofiller can further enhance dielectric strength and piezoelectric properties.…”

“…Due to complex molecular structures of textile dyes, it s difficult to remove colors by conventional treatment methods (e.g. bleaching, ozonation, hydrogen peroxide/UV, and electrochemical techniques) [4]. They are stable to light, oxidizing agents, and aerobic digestion.…”

Influence of ZrO2 and TiO2 nano particles in P(VDF-TrFE) composite for energy harvesting application

“…TiO 2 nano particles are also used to improve the mechanical and electrical properties of PVDF. In PVDF/TiO 2 composite thin lm TiO 2 nano particle are used to enhance the β-phase and piezoelectric properties [5][6][7].
