Patent application: Cellulose capsules

Ben Welter - Tuesday, February 06, 2018

U.S. patent application 20180019036 (applicant Technion Research & Development Foundation Ltd., Haifa, Israel):

"A method for making an oil-in-water dispersion or water-in-oil dispersion is disclosed. The method comprises the step of mixing a hydrophilic medium, a hydrophobic composition and non-derivatized cellulose solution in an ionic liquid. ... The novel, highly stable nano/micro-scale slurries, based on cellulose encapsulated PCMs, have a relatively low viscosity at high concentrations, which increases their pumping efficiency and permits to increase the slurry concentration up to 45 wt. %, that allows to enlarge the efficiency of thermal energy transfer systems."
