Abstract
The electric performance of the PA66/PVDF blends filled with various amount of copolymer synthesized from vinyl acetate-maleic anhydride (VAMA) was investigated. PA66/VAMA/PVDF blends show high dielectric constants, low dielectric loss, and excellent breakdown strength, which were important indexes in the actual application of dielectric material. The VAMA copolymer improves the dielectric and piezoelectric performance of the PA66/PVDF blends. Meanwhile, the addition of VAMA obviously decreases the dielectric loss and breakdown strength of the blends. PA66/PVDF blends filled with 3 wt% VAMA exhibited the best electric ability. The stable dielectric constants of the all-polymeric blends can be tuned by adjusting the content of the VAMA. The created all-polymeric blends represent a novel dielectric material that is technologically simple and easy to process forward application for flexible electronics.
Highlights
With the continuous development of science and technology, the need of high performance material urges people to open up the composites, which display their advantages outweighing their components, and it is hard for single polymer to meet requirements [1,2,3]
The infrared spectrum of PA66/VAMA/PVDF samples were not bonded well (PA66)/vinyl acetate-maleic anhydride (VAMA)/Polyvinylidene fluoride (PVDF) was tested by Fourier transformation infrared spectrometric analyzer
We have demonstrated a simple, efficient, and repeatable route to produce discontinuously all-polymer blends composed of PA66 and PVDF
Summary
With the continuous development of science and technology, the need of high performance material urges people to open up the composites, which display their advantages outweighing their components, and it is hard for single polymer to meet requirements [1,2,3]. A blend of PA66 and PVDF offers a strong potential for the application in the field of capacitor [9]. According to the property index requirements of energy storage material, the polymers selected should have two features: (1) the polymer itself should be partly crystallized and (2) the molecular chain of the polymer should have polar groups. This makes the polymer have a more sophisticated orientation under the action of electric field. VAMA offers a strong potential in the application of the allpolymer blends [11]
