Summary: This research establishes a hierarchical model to quantitatively evaluate the tunable AC electric responses of decoration-coated CNTs in PDA@MWCNT/PVDF nanocomposites. It reveals various functionalized interface effects between constituents based on decoration-dependent tunneling distance, electron hopping time, and relaxation time of dielectrics. The study also calculates the effective AC conductivity, permittivity, and dielectric loss of decorated nanocomposites through a combined effective-medium approximation and Mori-Tanaka method.

Summary: In this study, the effects of single-walled carbon nanotubes (SWCNTs)/poly(3,4-ethylene dioxythiophene) poly(4-styrene sulfonate) (PEDOT:PSS) composite-treated cotton on the transparency and conductivity of pure cotton were systematically investigated using a four-probe stack made of copper (Cu). The composite cotton exhibited a surface resistance of 0.08 ohm/cm, which remained stable even after 3 months. Various characterization techniques, such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), were employed to evaluate the structural, morphological, and thermal properties of the composite cotton. The results suggest that cotton fabric has great potential for applications in smart wearable textiles and supercapacitors.

Summary: PVDF membranes blended with different amounts of MWCNT-ZnO nanocomposites were prepared, and their structural and morphological properties were investigated. The hydrophilicity of the membrane increased with the increase of nanocomposite content, as shown by the reduced contact angle. Blending 0.5% of MWCNT-ZnO in a PVDF membrane achieved 85% removal rate of RbB under UV light irradiation. The pollutant removal occurred through the processes of adsorption and photocatalysis, improving the membrane's self-cleaning property and lifetime.

Summary: This paper investigates the effect of ferroelectric filler size and clustering on the dielectric properties of 20%BaTiO3-80%PVDF and 20%(2%Ag-98%BaTiO3)-PVDF hybrid nanocomposites. Finite element calculations reveal that fillers with epsilon > 103 do not enhance the permittivity in the composites, and the effective dielectric constant saturates to specific values determined by filler size and clustering. Addition of metallic ultrafine nanoparticles (Ag) increases the permittivity, especially when they are well connected to the ferroelectric particles' surfaces. Experimental dielectric analysis confirms the trends predicted by simulations, with slightly higher permittivity values likely due to changes in polymer phase composition and local inhomogeneity caused by nanofillers and clustering.

Summary: In this study, PD was synthesized by varying the volume fractions of MWCNT (fMWCNT) into the PVDF polymer matrix using a novel cold-pressing method. The structure, microstructure, and electrical properties of the samples were analyzed using XRD, FESEM, and Impedance analyzer. The results show that the distribution of MWCNT in PD increases with the increase of fMWCNT, leading to the clustering of MWCNT. The PD undergoes an insulator to metal transition, and the critical exponents were determined. Impedance, Nyquist, and modulus spectra were used to understand the relaxation behavior and microstructure of the PD samples.

Summary: Conductive polymeric materials are obtained by adding conductive nanoparticles to blends of immiscible polymers, but processing can alter the morphology and properties. This study examines the effect of shear deformation on a polypropylene/polystyrene/multiwall carbon nanotubes system. The results show that deformation causes coarsening of the blend morphology and disruption of the electrical network, increasing both rheological and electrical percolation thresholds. The evolution of properties depends on MWCNT concentration, strain amplitude, and shear rate.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.
