Water-dispersible and ferroelectric PEGylated barium titanate nanoparticles

Abstract: Dispersions of ferroelectric nanoparticles in aqueous medium can find promising applications in electro-optical, medical, and smart fluid technologies. In this report, we show the development of highly dispersed nano-sized ferroelectric...

“…Furthermore, the formation of nearly monodisperse and uniform BTPs is also attributed to the uniform nucleation of continuous heating at higher temperatures [43,44]. As shown in Figure S10 and Table S3, the absolute values of the Zeta potential of BT samples are greater than 30 mV, which proves that the dispersion is good [45,46]. Good uniformity reduces the statistical error of the average particle size of samples and benefits the performance of the assembled MLCCs.…”

“…This result is consistent with our previous study, where this observation was interpreted as aggregates comprising a few BaTiO 3 NPs. 23 Solutions including SDBS show a size reduction to (≈ 105 ± 3 nm) for all added surfactant amounts. The hydrodynamic diameter fluctuates between 110 to 160 nm for solutions containing SPAN80, with no clear discernable trend.…”

“…The synthesis method and complete characterization have been reported in detail elsewhere. 23 In a representative protocol, 1 mmol of Ba(acac) 2 •xH 2 O powder and 1 mmol of (O-i-Pr) 2 Ti(acac) 2 solution were mixed in 3 mL of PEG 400 in a round-bottom flask under a nitrogen atmosphere. This solution was stirred for 30 min.…”
