Aerogel could become the key to future terahertz technologies

https://phys.org/news/2023-12-aerogel-key-future-terahertz-technologies.html

"aerogel made of cellulose and conducting polymer PEDOT:PSS whose absorption of terahertz turned on- off through redox reaction... outdoor applications since water-repellent and can be naturally defrosted via heating by sunlight... conducting polymers biocompatible, tunable (due to ability to change material's charge density), durable... cellulose renewable and relatively low production cost... large modulation range 13 % and 91 %... medical imaging (X-ray substitute, safer), communication, space exploration, radar"
