A unique nanowire coating that provides additional functionality to fibers.
Cotton has long been used to make a soft, breathable, and durable textile. Various metal, semiconductor, organic and carbon-based materials have been integrated into cotton textiles to enhance and incorporate the unique mechanical, optical, and electrical properties of cotton. Nanoparticle coating is a commonly used method for modifying cotton textiles. However, the discontinuity of nanoparticles limits their efficacy in cotton textile enhancement. Hence, there is a demand to develop a more powerful approach to advancing cotton textiles’ functions.
Researchers at Cornell University have developed a unique nanowire-based fiber coating. Initial data shows that nanowire-based cotton offers several advantages over nanoparticles, including multiplication in their functionality as well as providing increased mechanical strength.
- Exhibit better electrical connectivity compared to nanoparticles.
- When compared to the nanoparticle, strong signals can be obtained with fewer nanowires, leading to cost-saving in manufacturing.
- Robust coating and abrasion-resistant.
- The coating does not affect the properties of the textile.
- Nanowires exhibit polarization sensitivities which make polarization-sensitive photodetectors possible.
- Applying nanowires to barcode cotton textiles.
- Take advantage of nanowire optical and electrical properties to create cotton-based photodetectors.
- Nanowire-functionalized cotton textiles may possess other uses in the realm of medical, anti-counterfeiting, and photocatalytic applications.
