A research team at the Wess Institute at Harvard University showed a continuous liquid film in a nanoporous elastic substrate, somewhat similar to the tears gathered together to cover our eyes. When it is stretched or undergoes physical manipulation, it changes performance. Those operations cause the nanopores to become larger or smaller, which causes the continuous liquid surface to deform. When it is stretched, it becomes opaque and has a rough surface. These two features can be manipulated quickly and perfectly just by stretching. The author of the research paper wrote: "When the substrate is deformed, the liquid flows in the pores, causing the smooth and defect-free surface to become rough." Usually the material is neither hydrophobic nor hydrophilic. The material that the Weiss team has created can easily switch between the two states, partly due to its flexible pore size. Just like tears gathered to protect the eyes from dust, this liquid film can increase the amount when needed. The liquid film and the substrate can respond to stimuli to concentrate its performance and make them more effective. The research team hopes to extend the variability of this material to other characteristics, and will continue to create an elastic band that can respond to a series of stimuli. This technology can one day pave the way for responsive buildings, allowing them to make changes according to changes in environmental conditions, and adapting sunlight and heat to make the internal environment more comfortable. The founder of the institute, Donald Ingebo, said that this technology may become a rule changer in every field, such as oil and gas pipelines, microfluidics and optical systems, building design and construction, and so on.
