Case Study

Preparation of Titanium (IV) Oxide Nanoparticle Dispersed Polyester Resin Composites

Ismail, Amr S., et al. Arabian Journal for Science and Engineering, 2020, 45, 197-203.

TiO2 reinforced linear saturated polyester resin nanocomposites can be prepared by dispersing metal oxide powder into aqueous polyester dispersion. The composition and crystallinity of this polyester nanocomposite are greatly reduced due to ionization. Furthermore, it also exhibits a highly condensed morphology and has high conductivity values due to cross-linking and temperature. The biological activity of the nanocomposites has higher value than the free polyester.
Synthetic procedure of titanium (IV) oxide dispersed polyester resin nanocomposites
· An aqueous dispersion of polyester was prepared by adding 9.95 g of polyester to 50 ml of H2O under vigorous stirring for 3 h at room temperature.
· Metal oxides were added slowly as a powder and were vigorously stirred with 0.05 g of titanium (IV) oxide for 3 h such that a weight percent of 0.05 for metal oxide/polyester was established.
· The suspension was stirred for 3 h followed by aging for 48 h at 100 °C in an autoclave. Then after washing and drying, the final nanocomposite product was obtained.

Preparation of Titanium Dioxide-Based Photocatalytic Materials

Tsang, Chi Him A., et al. Environment International, 2019, 125, 200-228.

Titanium dioxide (TiO2) family materials have been widely studied as photocatalysts from pure TiO2 to chemically modified TiO2-based materials due to their strong activity in photocatalytic reactions. As a semiconductor photocatalyst, titanium dioxide has excellent properties such as non-toxicity, chemical stability, high photocatalytic activity, ability to form thin films on substrates, and environmental friendliness.
Synthesis of Chemically Modified Titanium Dioxide Photocatalyst
· Metal-doped TiO2: From ordinary metals to transition metal particles or ions, all can be used as dopants for TiO2. For example, Fe-doped TiO2 can be used to catalyze the photodecomposition of CH3Cl.
· Metal oxide doped TiO2: Common metal oxide dopants include WO3, MnO2, FeOx, YOx, VOx, NiO and ZnO, etc.
· Doping TiO2 with non-metal elements: Doping TiO2 with non-metal elements is also an effective candidate method, such as anions (N3-, C4-, S4-), halides (F-, I-) and amines.
· TiO2 supported on substrates: Nanomaterials can be used as carriers to support TiO2 to improve its photocatalytic performance. Examples include carbon nanotubes (CNTs), graphitic carbonitrile (gC3N4), carbon fibers, and graphene.
