 Titanium Dioxide “Photo Switch” Material Developed

The Functional Interfacial Material Team of the Organic Solids Lab in the Institute of Chemistry CAS has recently used titanium dioxide as raw material and developed a “photo switch” material with bright application prospect.   Titanium dioxide is a material with great stability. It is extensively used in photo decomposition of water, photo catalysis and photo/power conversion. It is an inorganic material with important application value. The research team has used the low-temperature hydrothermal method and prepared titanium dioxide film that has a lotus-leaf micrometer/nanometer composite structure and a crystal plane with the lowest surface energy. The function of a photo-induced, super hydrophobic/super hydrophilic reversible “photo switch” is achieved under UV-ray irradiation. The product can be used in new photo-controlled dynamic self-cleaning materials.    It is reported that the bionic and intelligent super hydrophobic/super hydrophilic “photo switch” has an extremely bright application prospect in gene transmission, non-loss liquid conveyance, micro fluid, biological chip and drug controlled release sectors.
