Cool textiles to beat the heat

09.11.2017

Air-conditioned buildings bring welcome relief to people coming in from the heat. But creating that comfort comes with a cost to our wallets and the environment in the form of increased energy bills and greenhouse gas emissions. Now researchers report in ACS Nano the development of a new material for clothing that we could one day don as our own personal cooling unit, without any external energy needed to power it.  

Functionalized clothes have become the norm in recent years. We now have moisture-wicking and smell-proof athletic gear, and shirts and tops coated with a chemical layer that blocks ultraviolet rays.

Clothes that help cool us down, however, have been harder to achieve.

So far, such attempts have resulted in materials that incorporate bulky components, require a lot of energy or are expensive. Liangbing Hu and colleagues at University of Maryland College Park wanted to see if they could come up with a more practical option.

The researchers combined boron nitride -- a material that transfers heat -- and polyvinyl alcohol to create a nanocomposite fiber that can be 3-D printed and woven into fabric.

Testing to simulate the material on skin showed that the composite is 1.5 to 2 times more efficient at moving heat away from the body when compared to pure polyvinyl alcohol or cotton fabrics, respectively.

Making clothes with the nanocomposite thread could help keep wearers comfortable and reduce the need to cool entire buildings, the researchers say.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
