New Soluble, Photosensitive Polymer Allows for Drawing in Liquid With Light
Added Nov 5, 2013 | Rate View top rated
Light has been used for drawing on solid surfaces like TV screens or LCD monitors, and these kinds of light-sensitive polymers are not new to chemists. But now, researchers from Finland's University of Helsinki have manufactured photochemically active polymers that can be dissolved in water or certain alcohols. The researchers say this discovery is particularly important for the development of new materials for optics and electronics. In their study, a laser was aimed at a solution into which the new soluble, photosensitive polymer was partially dissolved. When exposed to light, the polymer dissolved completely and left a clear form visible in the cloudy solution.
