  • METHOD FOR MODIFYING LOW ELECTRIC FIELD REFRIGERATION PERFORMANCE OF POLYVINYLIDENE FLUORIDE FERROELECTRIC POLYMER AND APPLICATION THEREOF
    Publication number: 20260226239
    Abstract: A method for modifying the low electric field refrigeration performance of a polyvinylidene fluoride ferroelectric polymer and an application thereof. A polyvinylidene fluoride multi-copolymer solution is reacted with an organic base to obtain a polyvinylidene fluoride ferroelectric polymer which has a reduced dielectric constant modified by double bonds, so that the overall concentration of a polarized region remains unchanged while an electrocaloric effect is improved under a low electric field. In the present invention, double bonds are generated by means of chemically modifying a polyvinylidene fluoride copolymer which contains a chlorine element, and the method has the advantages of a simple process, a short preparation period, mild reaction conditions, low costs, etc.

  • Materials for autonomous tracking, guiding, modulating, and harvesting of energetic emissions
    Patent number: 11572470
    Abstract: Tropistic materials incorporating a class of adaptively configurable materials capable of real-time detection, tracking, and processing incident stimulus are provided. Incident stimulus can comprise any energetic emission or signals, such as electromagnetic waves, acoustics waves, or magnetic fields. The materials comprise a deformable stimuli-responsive material, which can adapt configuratively to a specific stimulus, and may further comprise a plurality of absorbers or photo-sensitive molecules configured to convert external incident stimuli to the specific stimulus type toward which the deformable material is responsive.
