Please find below videos we are producing based on our research that highlight some of the fundamentals of smart materials. This project is just beginning, please check back for more videos and demonstrations in the future.
Microgel Volume Phase Transitions
This video shows the deswelling of poly(N-isopropylacrylamide) microgels assembled via microfluidics as a function of temperature, with data collected via the use of a hot stage microscope. You can see the discontinuity of the phase transition, with the majority of deswelling occurring over a very narrow (~5 degree Celsius) temperature range.
