Photocatalytic effect is a crucial element for achieving self-cleaning surfaces in an indoor environment. Self-cleaning surfaces minimise the need for labour intensive and costly cleaning and maintenance services.
However, commercially available self-cleaning solutions are typically in the form of coatings that wear off with time and require re-application, which is costly and time consuming. In view of the limitations of such self-cleaning coatings, a polymeric resin additive paste that enables long term photocatalytic effect using visible light has been developed.
Achieving long term photocatalytic effect using visible light, and without the use of coating, is the innovative aspect of this technology.
The developed polymer resin additive paste can be incorporated into the raw materials at the manufacturing stage to enable photocatalytic effect for achieving self-cleaning surfaces in an indoor environment. The photocatalytic capability enables the breaking down of organic particles while minimising the need for labour intensive, and costly cleaning and maintenance services. This additive paste is currently based on polyester and may be customizable to different polymeric materials, e.g. epoxy, polyurethane etc.
This polymer resin additive paste may be adapted into the raw materials used in the manufacturing phase to achieve long-term photocatalytic effect in indoor products and surfaces.
These products may potentially include anti-bacterial surfaces, water purification systems, anti-fouling surfaces, composite structures and architectural products that require long term and sustainable self-cleaning functions.
Product developers and manufacturers looking to incorporate long term photocatalytic capabilities into their indoor products may benefit from the use of this new technology developed.
