摘要

Poly(vinylidene fluoride) (PVDF) nanocomposites represent a transformative class of functional materials that synergistically integrate high-performance polymers with nanoscale additives to meet the evolving demands of modern technologies. Incorporation of 2D materials such as graphene and functionalized carbon nanotubes (CNTs) has been shown to act as effective nucleating agents, increasing β-phase formation up to 100% and piezoelectric response–d33 values exceeding 50 pC/N against 20–30 pC/N of bulk PVDF. Electrical conductivity reaches 1.2 × 103 cm2/V·s in annealed graphene/PVDF systems, alongside dielectric constant enhancements of over 300%. Hybrid PVDF–perovskite composite, enabled by defect engineering and interfacial coupling, demonstrated modulation of its optoelectronic behavior through mechanical stimulus. These nanocomposites are also widely utilized in self-powered wearable electronics, electromagnetic interference (EMI) shielding, and piezoelectric nanogenerators (PENGs), with record performances such as approximately 2.5 mW/cm2 power density and over 24% efficiency in perovskite-based solar cells, ultrasensitive pressure detection capabilities (<10 Pa) by graphene-embedded wearable sensing membranes. To support industrial translation, scalable processing techniques—including electrospinning, solution casting, and in situ perovskite crystallization—are critically evaluated for their compatibility with roll-to-roll manufacturing and 3D printing, further broadening the commercial viability and application landscape of PVDF nanocomposites. The integration of PVDF nanocomposites into flexible electronics and Internet-of-Things (IoT) platforms holds promise for revolutionizing energy autonomy and human–machine interfaces. This chapter synthesizes foundational insights regarding how nanofillers modify PVDF’s electroactive β-phase and its associative properties and examines the mechanisms by which these nanocomposites are used for certain prominent functional applications. Further, it outlines a strategic roadmap for commercialization, positioning PVDF nanocomposites as cornerstone materials for sustainable, multifunctional technologies.
