Ceramic‐polymer nanocomposites exhibit good dielectric constant, low dielectric loss and excellent storage capacity for energy. A spin‐coating method was used to create 30 vol% BaTiO3 (BT) nanoparticles and polyvinylidene fluoride (PVDF) nanocomposite films with a homogeneous thickness of around 7 μm. The findings indicated that, with increasing the quenching temperature, the dielectric constant of the nanocomposite films decreased at 100 Hz. The dielectric constant of the BT‐PVDF nanocomposite film was 75.4 after quenched in air at 100°C, which was 21.4% greater than the that of the unquenched film. The breakdown strength of the films increased with increasing quenching temperature and reached the maximum values of 1400 kV/cm and 1600 kV/cm at 160°C, respectively. The breakdown strength of the film quenched in liquid nitrogen reached a maximum of 1600 kV/cm at 140°C. With increasing of quenching temperature, the charging density of BT‐PVDF nanocomposite film increased first and then decreases, reaching the maximum value of 11.165 J/cm3 at 140°C, which was 146% higher than that of the unquenched film. Heat treatment will be an innovative method for improving the dielectric and energy‐storage capabilities of ceramic‐polymer nanocomposite films.Highlights The uniform thickness of the film prepared by spin‐coating was about 7 μm. The dielectric properties of the composite film after quenching processes were improved. The breakdown voltage and charging density were vastly enhanced after quenching processes.

“…[ 12 ] However, there are still some difficulties in the bulk utilization of polycarbonate construction formwork in architectural engineering due to the poor toughness and lower tensile strength as well as the high cost of pure polycarbonate material. [ 13–15 ] To overcome these deficiencies, inorganic materials such as montmorillonite, [ 16 ] carbon‐based nanofillers, [ 17,18 ] glass fibers, [ 19 ] nano calcium carbonate [ 20 ] and mineral fillers [ 21 ] have been widely used in the fabrication of polycarbonate composites. Well known that advanced composite materials have more excellent characteristics such as high strength, good heat resistance, and high dielectric constant.…”

In order to increase the applicability of wollastonite (Wo) in polycarbonate (PC) polymer, surface modification of Wo was carried out using different modifiers containing silane coupling agent KH570, stearic acid (SA), and sodium dodecylbenzene sulfonate. The physical, physic-chemical, and application properties of modified Wo were evaluated. Results showed that KH570 modified Wo had narrower particle size distribution, higher absolute zeta potential and were more evenly distributed. Scanning electron microscope study confirmed their changes in morphology and aspect ratio during the modification process. The tensile strength of Wo/PC composites, in which KH570-modified Wo was used were superior to those in which original Wo or other modifiers modified samples were used. The maximum tensile strength of 65 ± 1 MPa was obtained by adding 15 wt% KH570-modified Wo. Thermal analysis indicated that adding Wo to the polycarbonate increased the residue content but decreased the thermal decomposition temperature and glass transition temperature slightly, regardless of unmodified or modified Wo. These results indicated that the well-modified Wo mineral had the potential to replace expensive carbon and glass fibers as fillers in polycarbonate products.

“…To improve the mechanical properties of Bs/Pm, several kinds of nanofillers, including nanoparticles, nanotubes, and nanosheets, have been introduced to satisfy mechanical performance requirements. − In the cases, the incorporation of these nanofillers could achieve nanoscale reinforcement for Bs/Pm by the virtue of their nanostructure. − However, the strong van der Waals force between the nanofillers results in uneven dispersion and agglomeration. − Consequently, the mechanical properties of Bs/Pm fall short of the expectations. There are a number of challenges that need to be addressed to maximize the reinforcement efficiency. , Applying the nanofillers with a three-dimensional (3D) structure is an effective way to improve the reinforcement efficiency. − This has been well exemplified by several nanofillers featuring a 3D homogeneous structure.…”

Polymer composites have great potential applications in the hip joint replacement, where the combinations of high mechanical strength and excellent biotribological properties are required. In this work, a well-dispersed three-dimensional (3D) silicon nitride nanowire membrane (SNm) designed as a reinforcement and brushite (Bs) served as bioactive filler are constructed into the polymer matrix, forming SNm-reinforced Bs/polymer composites (SNm-Bs/Pm). Especially, SNm could form a 3D interlocked structure, where the ultralong silicon nitride nanowires are entangled with each other. SNm could effectively facilitate the penetration of the polymer matrix and improve the cohesion strength of the polymer, thereby promoting mechanical and biotribological properties for SNm-Bs/Pm. The performances for polymer composites are optimized by increasing the layer number of preform. By comparing SNm-Bs/Pm with one-layer preform, the tensile strength of SNm-Bs/Pm with six-layer preforms reaches 83.3 MPa with an increase of 767.7%. In addition, the friction coefficient and wear rate of SNm-Bs/Pm with six-layer preforms in fetal bovine serum medium achieve 0.06 and 0.21 × 10–14 m3(N·m)−1 and decrease by 82.4 and 72.4%, respectively. The present work provides a promising methodology of preparing interlocked SNm-reinforced polymer composites with enhanced mechanical and biotribological properties that are potential for hip joint replacement applications.
