a sun-blocking skin developed by researchers at The Hong Kong Polytechnic
nanoscale layer, made up of hybrid polymers and monomers, is presently
the subject of a US patent application. Originally supported by
a RGC grant, further funding came from the Innovation Technology
Fund when the researchs potential became clearer.
Dr Xin oversees the mix of materials. Right: Fabric without
and with the sun-block layer.
chemical layer, which can be applied to textiles using an inexpensive
conventional dip-and-squeeze process, is less than 100 nanometres
thick, about 0.0001 mm. It acts like a shield against harmful ultraviolet
sunlight, dramatically reducing the risks of sunburn, premature
skin ageing, and skin cancer.
to untreated fabric, the layer gives more than five times better
protection, said Principal Investigator Dr John Xin of PolyUs
Institute of Textiles and Clothing. And after 55 washes, the treated
fabric still has strong UV-absorbing qualities so is considered
permanent, he added.
research is now moving on to nanoscale stain-repelling and anti-microbial
