Effect of temperature on foamability using a thermoresponsive polymer

AIP Advances, 2018
We experimentally examine foam dynamics and foamability using a thermoresponsive polymer, Poly(n-isopropylacrylamide) or PNIPAM. Under a constant gas injection, our results show that temperature significantly affects the foam height produced.
