• Application: Barium titanate (BaTiO3, BT) is one of the widely used materials in electronic ceramics. Because of its very high permittivity, it could be used in capacitors with outstanding properties by doping. Because barium titanate is used in large quantities as a material in electronic devices, considerable energy savings could be achieved if barium titanate could be sintered at a reduced temperature. It is reported that for LTCC (Low Temperature Cc-fired Ceramics) application, barium titanate is sintering at 1000°C for 24 hours with the incorporation of silicate glass system. In addition, there is a report saying that a sintered body of relative density around 90% was achieved by 900°C for 8 hours by adding boron oxide or lead borate to a barium titanate.In electronic devices, e.g., as voltage-sensitive dielectric in so-called dielectric amplifiers, in computer elements, magnetic amplifiers, memory devices.

Case Study

Preparation of PEI-Coated Barium Titanate Nanoparticles for SHG Imaging and Gene Delivery

Dempsey C, et al. Colloids and Surfaces B: Biointerfaces, 2013, 112, 108-112.

In order to improve the efficiency of cellular uptake, barium titanate nanoparticles (BT NPs) were coated and modified with cationic polymer polyethyleneimine (PEI). The obtained BT-PEI composite has dual imaging and gene delivery capabilities, which can achieve high levels of gene delivery and support further use in coupled imaging and gene therapy.
Synthesis and characterization of PEI-modified BT
· To create BT-PEI complexes, a 1 mg/mL solution of Barium Titanate (BaTiO3, 200nm) was prepared in phosphate buffer (PB, pH 7.4, 10 mM) with 500 µL volume. Next, varying concentrations of PEI dissolved in PB were added drop by drop to the BT solution, totaling 500 µL. After that, the mixture was vigorously vortexed for 10 seconds. The solution was subsequently sonicated for 30 minutes.
· Dynamic light scattering (DLS) measurements were conducted using a Malvern Zetasizer. Low sizing disposable methacrylate cuvettes were utilized for size data, while disposable zeta cells were used for zeta potential measurements.
· To perform thermogravimetric analysis, TGA/DSC was employed. BT-PEI samples prepared as previously described were centrifuged at 17000 rcf for 10 minutes to sediment particles, washed with 1 mL PB, and centrifuged for an additional 5 minutes. The particles were then placed into alumina pans and run on the TGA, initially heating to 100°C for 1 hour before being ramped up to 500 °C at a rate of 2 °C/min.

Barium Titanate Nanofibers for Flexible Piezoelectric Device Applications

Wang F, et al. Sensors and Actuators A: Physical, 2015, 233, 195-201.

Barium titanate (BaTiO3) nanofibers can be successfully prepared by sol-gel based electrospinning technology, and the prepared BaTiO3 nanofibers have good local piezoelectric response. Furthermore, the oriented BaTiO3 nanofibers are combined with a PDMS polymer matrix to prepare a flexible piezoelectric device.
Preparation of BaTiO3 nanofibers by electrospinning
· Barium acetate and titanium isopropoxide were dissolved in separate solutions and then mixed to create a BaTiO3 precursor solution. This solution was combined with a polyvinyl pyrrolidone (PVP) solution to form a final BaTiO3 solution with a concentration of around 0.3 M. The mixture was then loaded into a syringe for electrospinning.
· The electrospinning process was carried out at specific conditions including 21 kV voltage, 18 cm spacing between the needle tip and collector, and a feed rate of 0.1 mm/min. The resulting nanofibers were dried at 90 °C for 2 hours and then thermally annealed at 750 °C for another 2 hours to obtain pure BaTiO3 fibers.
· The preparation procedures for piezoelectric device fabrication involved aligning BaTiO3 nanofibers using a parallel electrode set-up, transferring them to a plastic substrate with inter-digital electrodes, covering them with PDMS, curing at 60°C for 2 hours, poling in silicone oil under a 4 kV/mm electric field at 80°C, and recording electric output under bending excitation.
