Nano-coating films' 'turn' civil ceramics into high-end products

This coating helps the product not only glossy, beautiful but also capable of good bactericidal, not sticky, not sticky, easy to clean, not peeling, scratching.

Dr. Le Quang Tien Dung and colleagues of Hue University of Science successfully fabricated TiO ₂ thin films of nano- coated ceramic materials such as cups, bowls, cups, ceramic tiles, toilets, pots. wash . to create high quality ceramic products.

One of the nanomaterials researched by scientists around the world for many years is TiO ₂ nanomaterials . Oxidizing capacity of catalytic materials such as TiO ₂ reduces organic matter polluting in air and water has been studied for over 20 years. TiO ₂ semiconductors are non-toxic and are used as additives in various products such as cosmetics, food, pharmaceuticals .

The tea set is covered with thin TiO ₂ nano-film.

However, at nanometers, this material is a strong photocatalyst (the use of light to activate chemical reactions) and is widely used as a self-cleaning material for class. Surface coating in many applications. Oxidation capacity of nano-sized TiO ₂ when UV irradiation is much stronger than the oxidants commonly used to treat previous water such as chlorine, hydrogen peroxide or ozone. This photocatalyst process can be applied to treat domestic water, wastewater, toxic organic substances and pigments.

Share with Discovery Magazine, PhD. Le Quang Tien Dung - Chairman of the project, said the topic of successfully manufacturing high-quality ceramic products on nano-based TiO ₂ with the aim of creating nano-photocatalytic TiO2 thin film on ceramic materials. This coating helps products with good bactericidal ability; has a pearl-like effect, beautiful, creating high aesthetics; have lotus leaf effect so it is not sticky, not sticky, easy to clean; High surface hardness, no peeling, scratching.

"Due to the initiative in manufacturing high quality ceramic products based on nano TiO ₂ , the product will have low cost, high economic efficiency. In this topic, we focus on research and manufacturing. Successful TiO ₂ nano-thin film coated on civil ceramic materials such as cups, drinking cups, ceramic tiles, toilets, lavabo washbasins . to create high-class ceramic products based on nano TiO ₂ " Dr. Dung added

These are new, unique and high-tech products bearing Vietnamese brand names and opening new directions for the Vietnamese ceramics industry. These products have many advantages such as good bactericidal ability; has a pearl effect that creates high aesthetics; have lotus leaf effect so it is not sticky, not sticky, easy to clean; High surface hardness, no peeling, scratching.

With the ability to apply at the industrial scale, simple production process, fully active in raw materials, opening new directions for the ceramic industry, this solution has been awarded the Second Prize at the Creative Competition Technique of Thua Thien Hue province for the eighth time and the third prize of the National Science and Technology Innovation Award.
