“…The enhancement is attributed to the high aspect ratio of BTnws and hydrogen bonds between F atoms and surface hydroxyl groups, which induce orientation polarization and interfacial polarization, respectively . Besides, the large dielectric constant of BaTiO 3 also contributes to the improved dielectric properties . The dielectric relaxation phenomenon is observed in Figure .…”

Dielectric nanocomposites with ceramic fillers have a crucial role in energy storage applications. Therefore, poly(vinylidene fluoride) (PVDF) based nanocomposites filled with 20 nm diameter, surface hydroxylated BaTiO3 nanowires (BTnws) were produced by solution‐casting method in this work, in which BTnws were synthesized via solvothermal method. The dielectric constant of BTnws/PVDF nanocomposites was 24 when the content of fillers was 10vol% at 100 Hz and the breakdown strength could increase up to 417 kV/mm before decreasing. The nanocomposites showed enhanced energy density performance and the maximum energy density could reach to 8.1J/cm3 at 320 kV/mm with 10vol% BTnws, nearly tripled that of pure PVDF at 300 kV/mm. Finite element and molecular dynamic simulation results revealed that thin BTnws could create dielectric homogeneity in the nanocomposites and have strong interface interaction with PVDF molecular. The ultrathin BTnws provided the possibility that single PVDF molecular could wrap on its surface, but this molecular wrapping pattern would not occur when the diameter of BTnws was large. Besides, the wrapping pattern could be reinforced by interactions between surface hydroxyl groups of BTnws and F atoms of PVDF molecular. Such contributions could induce good interface compatibility and lead to the improvement of energy density.

“…Results of dielectric constants indicated gradual decrease when measured at higher frequencies. This can be attributed to dipole mobility reduction where the dipoles are not sufficiently mobile to displace at the same pace as the frequency of the applied electric field exceeds the relaxation frequency . Dielectric loss generally results at a high value when a relatively low frequency is applied (interfacial polarization) and at a low value when the frequency increases.…”

A simple and facile method was developed to fabricate functional bulk barium titanate (BaTiO3, BT) ceramics using the paste extrusion 3D printing technique. The BT ceramic is a lead‐free ferroelectric material widely used for various applications in sensors, energy storage, and harvesting. There are several traditional methods (eg, tape casting) to process bulk BT ceramics but they have disadvantages such as difficult handing without shape deformation, demolding, complex geometric shapes, expansive molds, etc. In this research, we utilized the paste extrusion 3D printing technique to overcome the traditional issues and developed printable ceramic suspensions containing BT ceramic powder, polyvinylidene fluoride (PVDF), N,N‐dimethylformamide (DMF) through simple mixing method and chemical formulation. This PVDF solution erformed multiple roles of binder, plasticizer, and dispersant for excellent manufacturability while providing high volume percent and density of the final bulk ceramic. Based on empirical data, it was found that the maximum binder ratio with good viscosity and retention for desired geometry is 1:8.8, while the maximum BT content is 35.45 vol% (77.01 wt%) in order to achieve maximum density of 3.93 g/cm3 (65.3%) for 3D printed BT ceramic. Among different sintering temperatures, it was observed that the sintered BT ceramic at 1400°C had highest grain growth and tetragonality which affected high performing piezoelectric and dielectric properties, 200 pC/N and 4730 at 103 Hz respectively. This paste extrusion 3D printing technique and simple synthesis method for ceramic suspensions are expected to enable rapid massive production, customization, design flexibility of the bulk piezoelectric and dielectric devices for next generation technology.

“…One of the main reason to using with additive manufacturing processes rather than conventional engineering is the ability to reach the market from prototype design to 3d printed completed electronic circuits in very small spaces with stipulated time [9] [10] . Technology always play the major role to switch over the old manufacturing process to new manufacturing process but in recent years it has been set a new level in the manufacturing field through the 3D printing technology [11] . Instead of using separate circuit boards, large number of wiring and hard-hitting connections is massively reduced the overall process under control to maintain the more reliable and user friendly manufacturing methods.…”
