“…The combination of these electronic properties and flexibility makes this polymer a promising candidate for preparing self-powered electronic skins (e-skins) for health monitoring (Mahanty et al, 2020;Miki et al, 2019). Titania (TiO 2 ) nanoparticles and graphene oxide (GO) nanosheets have been incorporated into PVDF, aiming to obtain materials for use as a separator in lithium-ion batteries (Khassi, Youssefi and Semnani, 2020), antifouling membranes (Du et al, 2019;Mohamat et al, 2021), self-cleaning and ultraviolet (UV) light-resistant coatings (Liu, Zhanjian et al, 2021), and photocatalytic materials (Abdelmaksoud et al, 2021). TiO 2 is probably the most investigated semiconductor, having three main polymorphic phases, namely anatase, rutile, and brookite (Hanaor & Sorrell, 2011).…”

Polyvinylidene fluoride (PVDF) is a versatile and low-cost polymer with high biocompatibility, mechanical strength, chemical resistance, thermal stability, and ferroelectricity. This material has been widely used in many applications, ranging from membranes to electronic devices. In this study, self-supporting, flexible, and lightweight PVDF films were prepared by an evaporation route using a low-toxicity solvent (dimethyl sulfoxide -DMSO). Graphene oxide (GO) and anatase titania (TiO 2 ) were incorporated into the PVDF after preparing DMSO-based suspensions of these materials. The prepared materials were examined in terms of their structural, electrical, and wetting properties before and after exposure to near ultraviolet (UV-A) light. Substantial structural changes took place after incorporating GO and TiO 2 into PVDF. Such modifications were accompanied by dramatic changes in the wetting and electrical properties of the PVDF. UV-A light caused the formation of surface defects on PVDF and GO films. In addition, it promoted the photoreduction of GO into reduced graphene oxide (rGO). Composites containing TiO 2 showed high resistance to UV-A light, probably because titania particles absorb the incoming photons and shield the polymer matrix. This study provides new insights into the synthesis and characterization of PVDF/TiO 2 /GO composite films, which may be useful for many applications, including flexible electronics, solar cells, and biomedical devices.
