Aerogel Can Become the Key to Future Terahertz Technologies - Technology Org

High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Aerogels could be a nice addition to this. 

Researchers at Linköping University, Sweden, have shown, in a study published in the journal Advanced Science, that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves

The terahertz range covers wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. It has a very high frequency.

Thanks to this, many researchers believe that the terahertz range has great potential for use in space exploration, security technology and communication systems, among other things. In medical imaging, it can also be an interesting substitute for X-ray examinations as the waves can pass through most non-conductive materials without damaging any tissue.

However, there are several technological barriers to overcome before terahertz signals can be widely used. For example, it is difficult to create terahertz radiation in an efficient way and materials that can receive and adjust the transmission of terahertz waves are needed.

Adjustable filter

Researchers at Linköping University have now developed a material whose absorption of terahertz signals can be turned on and off through a redox reaction. The material is an aerogel, which is one of the world’s lightest solid materials.

“It’s like an adjustable filter for terahertz light. In one state, the electromagnetic signal will not be absorbed and in the other state it can. That property can be useful for long-range signals from space or radar signals,” says Shangzhi Chen, postdoc at the Laboratory of Organic Electronics, LOE, at Linköping University.

The Linköping researchers used a conducting polymer, PEDOT:PSS, and cellulose to create their aerogel. They also designed the aerogel with outdoor applications in mind. It is both water-repellent (hydrophobic) and can be naturally defrosted via heating by sunlight.

Large modulation range

Conducting polymers have many advantages over other materials used to create tunable materials. Among other things, they are biocompatible, durable, and have a great ability to be tuned. The tunability comes from the ability to change the charge density in the material. The great advantages of cellulose are the relatively low production cost compared to other similar materials and that it is a renewable material which is key for sustainable applications.

“The transmission of terahertz waves in a broad frequency range could be regulated between around 13 % and 91 %, which is a very large modulation range,” says Chaoyang Kuang, postdoc at LOE.

The study was funded by, among others, the Swedish Research Council, the Foundation for Strategic Research, the Foundation for Internationalization of Higher Education and Research, the Knut and Alice Wallenberg Foundation, the Wallenberg Wood Science Centre, and through the Swedish government’s strategic initiative in new functional materials, AFM, at Linköping University.

Facts: The terahertz range covers the wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. The waves have a width of between 0.1 and 1 millimetre and the frequency is at least 0.3 terahertz and at most 30 terahertz. 1 terahertz means that 1000 billion waves are sent or received in one second.

From cannabis harvest to flexible solar panels: Using organic electronics to develop next-gen devices

Organic electronics—electronics where the active material is carbon-based—are making possible diverse new technologies ranging from sensors for monitoring cannabinoid levels in cannabis plants to lightweight, bendable solar panels. Real-world applications could result in solar panels you roll up and take with you on your next camping trip, or cannabis producers knowing the optimal time to harvest plants. Key to these advances is a class of substances called conductive polymers, which have good optical and mechanical properties but are cheaper to manufacture than conventional electronics, thanks to low energy requirements; they can be printed in long, thin sheets—like a newspaper—but don't require the same high temperatures (> 1,000°C). Researchers from the University of Ottawa recently used the Canadian Light Source (CLS) at the University of Saskatchewan to study how different manufacturing processes can affect the performance of the resulting electronic devices.

Conductive Polymers Market - Forecast(2024 - 2030)

Conductive Polymers Market Overview

The Conductive Polymers Market size is forecasted to grow at a CAGR of 7.3% during the forecast period 2024-2030 and reach US$8.6 billion by 2030. Conductive polymers are organic polymers capable of conducting electricity. They can be categorized into various types which include polyacetylene, polyaniline, polyfuran, polythiophene, polypyrrole and more. Conductive polymers are primarily used in the automotive industry for the production of LED lighting, sensors, batteries and other electronic applications. For instance, according to the European Automobile Manufacturers Association, 85.4 million motor vehicles were produced globally in 2022, a 5.7% increase from 2021. An increase in automotive production along with the surging demand from the solar power industry is expected to drive the growth of the conductive polymers market size in the upcoming years. On the other hand, the low conductivity of conductive polymers may confine the growth of the market. The conductive polymers market is witnessing significant trends shaped by technological advancements and the demand for innovative electronic applications. With a growing focus on lightweight and flexible electronics, conductive polymers are gaining prominence.

Successful synthesis of helical conductive polymers with circular polarization activity in response to magnetic fields

Researchers at University of Tsukuba have synthesized a helical, magnetically active conductive polymer with exceptionally high optical activity using cyclosporine A as a helix-inducing agent. This polymer exhibits distinct absorption of circularly polarized light, corresponding to the orientation of an applied magnetic field. In the realm of semiconductors, spintronics—a technology that manipulates electronic devices by controlling electron spin within magnetic fields—has gained considerable attention for its potential application in communication technologies. Traditionally, research in this area has predominantly focused on inorganic magnetic materials; only a few studies have investigated organic electronics, particularly conductive polymers. Drawing on extensive experience in topological magnetism dating back to the late 1990s, the University of Tsukuba research team has reported several innovative organic magnetic materials in the spintronics domain.
