Titania-Coated Polystyrene Hybrid Microballs Prepared with Miniemulsion Polymerization

Abstract

Hybrid microballs with polystyrene cores coated by titania nanoparticles were prepared in miniemulsion polymerization. Acrylic acid was used as a comonomer to promote locating titania nanoparticles on the polymer's surface. The addition of a hydrophobic agent effectively prevents monomer diffusing into the aqueous phase. The morphology of hybrid particles was examined with the transmission electron microscope, and its change pattern with reactive conditions was observed. The infrared spectra of hybrid nanoparticles showed that there existed a certain interaction between titania nanoparticles and polymers. The crystallization morphology of hybrid particles before and after calcination was characterized with X-ray diffraction.

Morphology, Mechanical and Thermal Properties of PBT-TiO2Polymer Nanocomposite

“…Many attention has been focused on the new materials that can demonstrate photocatalytic behavior under the proper illumination conditions for applications in solar cell industrial and textile industrial [7,8]. For this reason, nanotitanium dioxide (TiO 2 ) has attracted great attention as a semiconductor photocatalyst due to its widely used materials, low cost, good stability, and ease of preparation [9].…”

The effect of nano-Zinc oxide on the self-cleaning properties of cotton fabrics for textile application

“…Particularly, hybrid polymer materials at nanometer scale, the design and synthesis of nanoscale objects require a good deal of control over interfaces in order to build up and organize the nanostructures. [1] Furthermore, the combination of multitechnologies such as nanotechnology, biotechnology and polymer technology can offer multifunctional, versatile, stable, resistant and non-toxic products which results in outstanding properties in the wind range of high value industrials, foods and medicals applications such as anti-microbial, anti-oxidant, anti-bacterial and self-cleaning properties. [1,2] Recently, much interest in new materials that can demonstrate photocatalytic behavior under the proper illumination conditions for applications in textile industrials.…”

“…[4] One of an interesting application of metal oxide is self-cleaning ability. [1,5,6] Nano zinc oxide (nano-ZnO) exhibits low dielectric constant, large electromechanical coupling coefficient, high luminous transmittance, high catalysis activity, intensive ultra-violet and infrared absorption, and etc. Therefore, nano-ZnO can potentially be applied to self-cleaning ability and UV-shielding materials.…”

The photocatalytic activities of nano-titanium dioxide on the cotton fabrics for self-cleaning properties

“…[5] One of an interesting application of TiO2 is self-cleaning ability. [6][7][8] Titanium dioxide is present in three crystalline phases: rutile, anatase and brookite. Among these three forms, rutile is more stable than the other two forms.…”
