Barium titanate (BaTiO3, BTO), conventionally used for dielectric and ferroelectric applications, has been assessed for biomedical applications, such as its utilization as a radiopacifier in mineral trioxide aggregates (MTA) for endodontic treatment. In the present study, BTO powders were prepared using the sol-gel process, followed by calcination at 400–1100 °C. The X-ray diffraction technique was then used to examine the as-prepared powders to elucidate the effect of calcination on the phase composition and crystalline size of BTO. Calcined BTO powders were then used as radiopacifiers for MTA. MTA-like cements were investigated to determine the optimal calcination temperature based on the radiopacity and diametral tensile strength (DTS). The experimental results showed that the formation of BTO phase was observed after calcination at temperatures of 600 °C and above. The calcined powders were a mixture of BaTiO3 phase with residual BaCO3 and/or Ba2TiO4 phases. The performance of MTA-like cements with BTO addition increased with increasing calcination temperature up to 1000 °C. The radiopacity, however, decreased after 7 days of simulated oral environmental storage, whereas an increase in DTS was observed. Optimal MTA-like cement was obtained by adding 40 wt.% 1000 °C-calcined BTO powder, with its resulting radiopacity and DTS at 4.83 ± 0.61 mmAl and 2.86 ± 0.33 MPa, respectively. After 7 days, the radiopacity decreased slightly to 4.69 ± 0.51 mmAl, accompanied by an increase in DTS to 3.13 ± 0.70 MPa. The optimal cement was biocompatible and verified using MG 63 and L929 cell lines, which exhibited cell viability higher than 95%.

Flexile composite film of Poly-3-hydroxyalkanoate−Perovskite−Tween 80 (PHA-PV-T80) as a green membrane film was prepared. Pristine medium-chain-length poly-3-hydroxyalkanoate (mcl-PHA), produced through bacterial fermentation, was blended with different concentrations of perovskite (PV) and Tween 80 (T80) ranging from 0.01 to 0.0025 % ( w/v) and 1.5 – 4.5 % ( w/v), respectively, to fabricate the composite films. Ultrasound irradiation was applied to aid homogenous dispersion of blend solution prior to film casting. The composite film exhibited improved physical properties compared to the neat mcl-PHA film, which is more susceptible to ripping upon peeling. Thorough distribution of perovskite, facilitated by T80, were responsible for promoting increased side-chain crystallization, resulting in the formation of extensive rigid regions within the PHA matrix, which significantly improved proton permeability of the composite film. PHA composites showed higher proton flux (>3.5 × 10−4 mol.min−1.cm−2) compared to neat PHA (1.03 × 10−4 mol.min−1.cm−2) and commercial Nafion (1.22 × 10−4 mol.min−1.cm−2). The relationship between physicochemical attributes and proton flux characteristics of the composite films were discussed with regards to their potential application as proton exchange membrane.
