Dielectric properties of poly(vinylidene fluoride)-grafted-BaTiO3 (PVDF-g-BT) core-shell structured nanocomposites obtained from Reversible Addition Fragmentation chain Transfer (RAFT) polymerization VDF were investigated by Broadband Spectroscopy (BDS). The dielectric constant increased along with the BT content, about +50% addition 15 vol% BT, which was around 40% more than expected predictions using usual modeling methods for composite materials, to be ascribed effect interfacial...
Core–shell structured PVDF-<italic>g</italic>-BaTiO<sub>3</sub> nanocomposites were prepared by surface-initiated RAFT of VDF from BaTiO<sub>3</sub> nanoparticles.
Core–double-shell-structured nanocomposite films consisting of polyvinylidene fluoride-grafted-barium titanate (PVDF-g-BT) incorporated into a P(VDF-co-hexafluoropropylene (HFP)) copolymer matrix were produced via solution mixing method for energy storage applications. The resulting thoroughly investigated spectroscopic, thermal, and morphological analyses. Thermogravimetric data provided an enhancement the thermal stability, while differential scanning calorimetry indicated increase in...
Abstract The dielectric properties of fluorinated cyano copolymer poly(acrylonitrile‐ co ‐2,2,2‐Trifluoroethyl methacrylate) (poly[AN‐ ‐MATRIF]), reinforced with a natural Moroccan beidellite nanoclay organomodified cetyltrimethylammonium bromide were studied. effect varying nanofillers loadings (1 wt%, 2 3 and 5 wt%) on the molecular dynamics was investigated using broadband spectroscopy from 10 −1 to 6 Hz temperatures ranging between 30°C 100°C. For matrix, real ( ε ′ ) imaginary parts ′′...
The first example of the usefulness titanium (IV) butoxide, as initiators for open air in-situ intercalative polymerization ε-caprolactone (ε-CL) in presence organoclay is herein reported. bionanocomposites based on poly(ε-caprolactone) (PCL) were prepared by Ring Opening Polymerization (ROP) different organomodified montmorillonite clay (ODA-MMT) loading (1, 3 and wt%). Structural, thermal mechanical characterizations resulting investigated. nanoclay increased PCL crystallinity, melting...
Abstract Naturally occurring halloysite nanotubes (HNTs) are first functionalized by 3‐(trimethoxysilyl) propyl methacrylate and then used as nanofillers in a mixture of difunctional methacrylates (triethylene glycol dimethacrylate bisphenol A glycerolate dimethacrylate). Upon free radical photocrosslinking this enables the situ preparation HNT/thermoset nanocomposites. The covalent bonding HNT thermoset matrix is proven following characteristic bands using Fourier transformed infrared...
Dielectric and electrical properties of bio-nanocomposites based on poly (?-caprolactone) (PCL) with different amounts organomodified montmorillonite clay (MMT-ODA) were investigated by broadband dielectric spectroscopy in the frequency range from 1Hz to 1MHz temperature -100 25°C. These nanocomposites prepared situ Ring Opening polymerization ?-caprolactone open air using titanium alkoxide as a catalyst. Due semicrystalline structure PCL, high number modes its overlap, relaxation patterns...

Abstract The usefulness of fluoropolymers (PFs) in various items for vehicles, shuttles, and space‐crafts is presented, considering their synthesis, properties, applications, recycling. advantages FPs are first supplied, including outstanding properties (chemical, oxidative, thermal resistances, excellent weatherability durability to avoid obsolescence), as well synthesis usually achieved by conventional radical copolymerization fluoromonomers. They can be composites shape memory polymers or...
