Emulsion Microgel Particles as High-Performance Bio-Lubricants [PDF]
ACS Applied Materials & Interfaces, 2018 Starch-based emulsion microgel particles with different starch (15 and 20 wt %) and oil contents (0-15 wt %) were synthesized, and their lubrication performance under physiological conditions was investigated. Emulsion microgels were subjected to skin mimicking or oral cavity mimicking conditions, i.e., smooth hydrophobic polydimethylsiloxane ball-on ...
