Abstract

<jats:p>Smart textiles have received a lot of attention of research in the last decade due to some of their unique features. The introduction of intelligent materials into textile structures offers an opportunity to develop multifunctional textiles, such as sensing, reacting, conducting electricity and performing energy conversion operations. In this work, we develop an intelligent electro-active textile using an economic and ecological method. The nanocomposite studied is cotton-based textiles CT based on poly (vinylidene fluoride) (PVDF) - carbon nanofillers (CNF) - tetraethyl orthosilicate (TEOS), Si(OCH2CH3)4. The process uses N, N-dimethylformamide (DMF) solvent followed by evaporation to transform the passive (non-functional) textile into a piezoelectric (dynamic) textile. The SEM/EDX and FTIR spectra of cotton textile show that the addition of conducting nanocharges facilitates the formation of the phase β (piezoelectric) rather than the phase α (non-piezoelectric). Infrared spectroscopy (IR) analysis shows that the pure phase β dominates in CT by adding a mass fraction of 0.5 % CNF in the PVDF matrix. These results indicated that CNF has a high efficiency in transforming the phase α introduced in the unloaded PVDF, to the β-phase in the case of nanocomposites. Consequently, this fabricated piezo-smart textile exhibits glorious piezoelectricity even with relatively low coating content of PVDF-CNF-TEOS. We believe that our study may inspire the research area for future energy harvesting applications.</jats:p>
