“…Additionally, the peaks at 1179 and 1404 cm –1 were asymmetrically broadened (Figure a). The above results indicated that there was a hydrogen bond interaction between the π electron clouds over the N atom in PANI and the −CH 2 group in PVDF . As shown in Figure d, the peaks at 2987 and 3027 cm –1 , corresponding to symmetric and asymmetric stretching vibrational bands, respectively, were shifted to lower wavenumbers.…”

“…The nitrogen atom on the monomer aniline can form a strong coordination bond with the central atom Mo in MoS 2 , which provides a binding site for the in situ polymerization of PANI on MoS 2 . More significantly, π electron clouds over the N atom in PANI can interact with the −CH 2 groups in PVDF by hydrogen bond interactions, which can further promote the formation of the β phase . To the best of our knowledge, there was no study about using PANI-decorated MoS 2 to improve the piezoelectric performance of PVDF …”

Piezoelectric polyvinylidene fluoride (PVDF) provided an opportunity for non-invasive in situ electrical stimulation of cell behavior, yet its electroactive β phase was difficult to obtain due to its instability in the molten state. Herein, polyaniline (PANI) protrusions were in situ oxidation-polymerized on molybdenum disulfide (MoS2) nanosheets (PANI-MoS2). Then, PANI-MoS2 was introduced into laser additive-manufactured PVDF scaffolds. On the one hand, PANI protrusions produced steric hindrance between adjacent MoS2 nanosheets and inhibited the stacking and aggregating of MoS2. On the other hand, PANI-MoS2 could serve as a platform to achieve interfacial polarization locking. Specifically, Mo–S dipoles in MoS2 and π electron clouds over the N atom in PANI locked −CH2 dipoles in PVDF through electrostatic and hydrogen bond interactions, respectively, which forced −CH2 to align perpendicularly to the basal plane of MoS2 and bialy to one side of the PVDF main chain, thereby forming a full-reverse planar zigzag configuration of the polarized β phase and maintaining its stable existence. The results demonstrated that the β phase of the scaffolds was significantly increased from 43 to 90%, which resulted in an enhanced electrical output performance. The improved electrical output greatly promoted osteoblast-like cell proliferation and differentiation. Furthermore, owing to the pulling-out effect of MoS2 and improved interfacial stress transfer between MoS2 and the polymer matrix, the mechanical properties of scaffolds were also enhanced. These findings suggested that the piezoelectric scaffolds had great potential in bone tissue engineering.

Energy harvesting is one of the most promising research areas to produce sustainable power sources from the ambient environment. Which found applications to attain the extensive lifetime self-powered operations of various devices such as MEMS wireless sensors, medical implants and wearable electronic devices. Piezoelectric nanogenerators can efficiently convert the vastly available mechanical energy into electrical energy to meet the requirements of low-powered electronic devices. Among the piezoelectric materials, poly (vinylidene fluoride) (PVDF) and its copolymers are extensively studied for the development of energy harvesting devices. Due to the outstanding properties such as high flexibility, ease of processing, long-term stability, biocompatibility makes them a promising candidate for piezoelectric generators. Nevertheless, compared to piezoceramic materials, PVDF based generators produce lower piezoresponse. Over the last decades, tremendous research activities have been reported to endorse the performance of PVDF based energy harvesters. This review article mainly focused on the recent progress in the performance improvement with processing methods, piezoelectric materials, different filler loading. The new developments and design structures will lead to an increase in piezoelectricity, alignment of dipoles, dielectric properties and subsequently enhance the output performance of the device. Electronic circuits play a vital role in energy harvesting to efficiently collect the developed charge from the device. Here, we have proposed a detailed description of the electronic circuits. Also, in the application part deals with the recent progress in flexible, biomedical and hybrid generators based on PVDF polymers.

With the rapid growth of numerous portable electronics, it is critical to develop high-performance, lightweight, and environmentally sustainable energy generation and power supply systems. The flexible nanogenerators, including piezoelectric nanogenerators (PENG) and triboelectric nanogenerators (TENG), are currently viable candidates for combination with personal devices and wireless sensors to achieve sustained energy for long-term working circumstances due to their great mechanical qualities, superior environmental adaptability, and outstanding energy-harvesting performance. Conductive materials for electrode as the critical component in nanogenerators, have been intensively investigated to optimize their performance and avoid high-cost and time-consuming manufacture processing. Recently, because of their low cost, large-scale production, simple synthesis procedures, and controlled electrical conductivity, conducting polymers (CPs) have been utilized in a wide range of scientific domains. CPs have also become increasingly significant in nanogenerators. In this review, we summarize the recent advances on CP-based PENG and TENG for biomechanical energy harvesting. A thorough overview of recent advancements and development of CP-based nanogenerators with various configurations are presented and prospects of scientific and technological challenges from performance to potential applications are discussed.
