Published in 2025 at "Journal of Applied Polymer Science"

DOI: 10.1002/app.57271

Abstract: Volatile decalin as a solvent to prepare porous UHMWPE membrane is explored in this paper. Capillary force will lead to pore collapse, so decalin cannot be volatiled in the drawing process, and it must be… read more here.
