摘要

Abstract

Piezoelectric elastic composites based on polydimethylsiloxane (PDMS) elastomer filled with polar phase poly(vinylidene fluoride) (PVDF) microspheres are fabricated. The regulatory role of the elastic polymer matrix structure on the performance of the composite

which is less concerned in previous studies

is explored. Here

we have elucidated that precise control of the PDMS crosslinked network governs the stress transfer mechanism

enabling rational design of high-performance piezoelectric composites. By tuning the crosslinker ratio

we achieve PDMS crosslinking densities ranging from 9.9×10

–6

mol·cm

–3

to 91.3×10

–6

mol·cm

–3

enhancing the output voltage of the piezoelectric composite with 10 wt% PVDF microsphere content from 5.3 V to 19.8 V. Finite element simulation attributes this enhancement to more efficient stress transfer within the elastomer matrix with higher crosslinking density

strength

ening the dipole polarization response of polar PVDF microspheres. By increasing PVDF microsphere content to 30 wt%

the composite exhibits a piezoelectric coefficient (

) of 74 pC·N

–1

and a sensitivity of 647 mV·N

–1

which are 37 and 20 times higher than unoptimized composites in this work

respectively. This work advances understanding of mechanoelectrical coupling in flexible piezocomposites and provides a platform for designing next-generation sensors for intelligent robotics and non-contact acoustic sensing.
