Two-dimensional (2D) films of conjugated porous organic polymers (C-POPs) can translate the rich in-plane functionalities frameworks into diverse optical and electronic applications while addressing processability issues their crystalline analogs for adaptable device architectures. However, lack facile single-step synthetic routes to obtain large-area high-quality 2D-C-POPs has limited application possibilities so far. Here, we report synthesis four mechanically robust imine-linked 2D-C-POP...
Conventional ceramic based piezoelectric materials are brittle, which restricts their use in energy harvesting where flexibility is required. Polymer counterparts flexible but exhibit comparatively reduced electrical output. Here, we provide a method that overcomes these challenges through design of composites comprised polymer matrix (PVDF-TrFE) and filler nanoparticles (niobium-doped Pb(Zr,Ti)O3). Nanoparticles were functionalized with trimethoxysilylpropyl methacrylate (TMSPM) promotes...
For a variety of mechanical energy harvesting as well biomedical device applications, flexible devices are useful which require the development environment-friendly and robust materials devices. In this manuscript, we demonstrate lead-free, facile, low-cost, sol–gel-processed reduced graphene oxide (rGO)/P(VDF-TrFE) nanocomposite with multipurpose capability demonstration piezoelectric nanogenerator (PENG) hybrid triboelectric (HPTENG) The structural analysis shows that interactions between...

Propelled by the development of Internet things and other low-power devices such as in health care or sensing applications, there is growing emphasis on energy harvesting based piezoelectric triboelectric harvesting. We demonstrate a highly flexible transparent nanogenerator (TENG) prepared incorporating maghemite (γ-Fe2O3) fillers polyvinylidene fluoride (PVDF) with polyethylene terephthalate (PET) counterpart for potential application powering wearable electronic devices. Addition γ-Fe2O3...
Abstract We have demonstrated an in situ route to design barium titanate (BT)@polyvinyl pyrrolidone (PVP) nanoparticles (NPs) PVP/polyvinylidene fluoride (PVDF) blends. Thus, the PVP simultaneously acted as a linker and part of polymer matrix. hydrothermally synthesized tetragonal phase BT NPs (~150 nm). The content was varied from 0 15 vol%. resulting nanocomposites generated enormous interfaces because homogeneously dispersed BT@PVP NPs. Furthermore, tailored interfacial properties...
