Ferroelectric polymers reinforced with noble metals enable advanced sensors, photodetectors, flexible electronics, and energy harvesters. This study investigates the effects of integrating hexagonal nanogold (n-Au) into poly(vinylidene fluoride) (PVDF), a prominent ferroelectric polymer, to advance the structure-property relationship in hybrid materials for next-generation sensor and energy conversion technologies. The fabricated Au-PVDF thin films (<= 100 nm) are exhibiting a nearly pure beta-PVDF phase with edge-on orientation of (300) lattice planes. This is a unique 2D architecture that is achieved by balancing Au-PVDF interfacial charges and plasmonic effects, resulting in enhanced piezo- and pyro-electric responses. Plasmon polaritons confined within the polymer matrix regulate collective dipole dynamics and electron transport in network channels, leading to surface-enhanced light absorption across the UV to IR spectrum. A pyroelectric device constructed using n-Au-PVDF thin films demonstrates superior performance with an in-plane pyroelectric coefficient of 20.6 mu Cm- 2K-1, generating 5.9 nA and 4.5 V under thermal fluctuations from 294 to 301 K. The improved response time is reduced to 20 ms, representing an 80 % improvement over the performance in PVDF composite pyroelectrics. It highlights the potential of n-Au-PVDF hybrids for applications in smart sensors, flexible electronics, waste-energy harvesting, and advanced photodetectors.
