According to the British "Daily Mail" reported on October 27th, Portuguese scientists have developed a nanocapsule that can be permanently attached to clothing. With the change of human body temperature, the capsule will absorb heat or melt and exothermally solidify. Balancing body temperature may be more likely to be used in the treatment of skin diseases in the future.
Scientists at the Portuguese Center for Nanotechnology and Smart Materials have developed a nanocapsule made from starch and containing traces of waxy substances. This capsule is 1,000 times smaller than the width of human hair and can be permanently attached to various types of clothing. On the other hand, even in the case of cleaning.
The design principle of the capsule is to imitate human sweat. When the human body temperature rises, the waxy substance in the capsule absorbs excess heat and melts into a liquid state to cool the human body. When the human body temperature decreases, the waxy substance solidifies and releases heat, which causes the human body to heat up. Maintain body temperature in a comfortable range.
"This technology is suitable for outdoor clothing, sportswear, but also for everyday wear, especially for those who are not good at regulating their body temperature, such as children and the elderly." Dr. Carla Silva, who led the study, said, "Nanocapsules It is covalently bonded to the fabric, which is the strongest chemical bond in nature." So even during the cleaning process, the capsules can adhere tightly to clothing.
In addition to clothing, the team also worked with the Belgian Chemicals and Textiles Corporation and some dermatology companies who wanted to kill natural bacteria by killing bacteria and treating painful skin conditions such as eczema. Dr. Carla Silva pointed out that the modified nanocapsules can release drugs at the bacteria that cause skin infections.
