Pore size control using a novel diluent mixture via a thermally induced phase separation process |
초록 |
Membranes with micropores are required for use as separators for lithium ion batteries. Polyethylene (PE) membranes containing controlled pore sizes were fabricated using a polytetramethylene glycol (PTMG) mixture with paraffin as a novel diluent via a thermally-induced phase separation (TIPS) process. The phase separation temperature of the PE//(paraffin/PTMG) ternary mixture increased with increasing PTMG content in the diluent mixture when PE content was fixed. At a fixed blend composition, the phase separation temperature of the PTMG/paraffin mixture increased as the molecular weight of the PTMG decreased, while that of the PE//(paraffin/PTMG) ternary mixture increased with increasing PTMG molecular weight. As a consequence, a PE membrane containing controlled pores was able to be fabricated using a diluent mixture containing PTMG and paraffin |
