“…Table 1 summarizes the fit parameters. The frequency exponent s varied in a narrow range between 0.5 and 0.8 suggesting, that ion hopping was the dominant conduction mechanism in all samples [13][14][15][16][17]. The frequency independent part of the conductivity steadily decreased with an increasing firing temperature, reaching the highest values for the raw samples.…”

Dependence of the AC conductivity of the C-130 type electroporcelain on the compaction pressure was measured. The samples were manufactured from spray-dried mixtures using isostatic compaction in vacuum at 5 different pressures (70 MPa to 110 MPa, 10 MPa step size). AC conductivity measurements were performed at 25 different frequencies ranging from 50 Hz to 3 MHz at room temperature on samples with dimensions 10 × 10 × 3 mm3. In addition to the compaction pressure, the effect of different firing temperatures was studied (1100°C and 1200°C). The highest values of AC conductivity were observed in the case of the raw samples, due to an amount of physically and structurally bound water. Conductivity relaxation was observed after firing at 1200°C in all samples at 2.5 MHz. A small effect of the compaction pressure was observed for the raw samples and samples fired at 1200°C.

“…Recent research articles have developed novel bio-based polymers and composite materials that not only offer enhanced printability but also align with the growing demand for eco-friendly manufacturing processes [ 6 , 7 , 8 , 9 , 10 ]. Furthermore, there is a notable emphasis on improving the precision and speed of 3D printing through innovations such as high-speed resin-based printing and advanced multi-material printing technologies [ 11 , 12 , 13 , 14 , 15 ]. The integration of artificial intelligence and machine learning algorithms to optimize print parameters and minimize defects is another exciting avenue explored in recent studies.…”

Digital light processing (DLP) techniques are widely employed in various engineering and design fields, particularly additive manufacturing. Acrylate resins utilized in DLP processes are well known for their versatility, which enables the production of defect-free 3D-printed products with excellent mechanical properties. This study aims to improve the mechanical and thermal properties of 3D-printed samples by incorporating mica as an inorganic filler at different concentrations (5%, 10%, and 15%) and optimizing the dispersion by adding a KH570 silane coupling agent. In this study, mica was introduced as a filler and combined with epoxy acrylate resin to fabricate a 3D-printed sample. Varying concentrations of mica (5%, 10%, and 15% w/w) were mixed with the epoxy acrylate resin at a concentration of 10%, demonstrating a tensile strength increase of 85% and a flexural strength increase of 132%. Additionally, thermal characteristics were analyzed using thermogravimetric analysis (TGA), and successful morphological investigations were conducted using scanning electron microscopy (SEM). Digital light-processing technology was selected for its printing accuracy and cost-effectiveness. The results encompass comprehensive studies of the mechanical, thermal, and morphological aspects that contribute to the advancement of additive manufacturing technology.

“…Mica is widespread in the natural environment. As an easily obtained layered silicate mineral, mica has attracted great attention because of its unique electric insulation, chemical durability, thermal stability, and lack of toxicity [16,17]. Many studies have been reported for mica applications in different polymer matrixes due to its superior performance in enhancing the properties of coatings [18][19][20].…”

In this work, a series of epoxy acrylate (EA)/mica composite coatings were synthesized through introducing mica powders of different particle size into epoxy acrylate coatings and using an ultraviolet (UV) curing technique to investigate the influence of mica particle size on the coatings. Mica powders of different particle sizes were obtained by ball-milling for 4, 8, 12, 16, and 20 h with a planetary high-energy ball mill. The particle size and morphologies of ball-milled mica powders were characterized by laser particle size analyzer and scanning electron microscopy (SEM). The results indicated that planetary ball-milling reduced the particle size of mica powders effectively. Mica powders that were un-ball-milled and ball-milled were added into the epoxy acrylate matrix by a blending method to synthesize the organic-inorganic UV curable coatings. The optical photographs of the coatings showed greater stability of liquid mixtures with smaller particle size fillers. The chemical structures of EA/mica composite coatings were investigated by Fourier transform infrared spectroscopy (FTIR), and the conversion rate of C=C bonds was calculated. The results indicated that the C=C conversion of coatings with mica powders of smaller particle sizes was higher. Tests of mechanical properties and tests using electrochemical impedance spectroscopy (EIS) showed that pencil hardness, impact resistance, and coating resistance were improved due to the reduction of mica powders particle size.
