METHOD FOR INCREASING THE STRENGTH AND SOLVENT RESISTANCE OF POLYIMIDE NANOWEBS |
摘要 |
The invention provides a method for enhancing the properties of polyimide nanowebs, the method comprising subjecting a nanoweb consisting essentially of a plurality of nanofibers of an aromatic polyimide to a temperature at least 50 C.° higher than the imidization temperature thereof for a period of time in the range of 5 seconds to 20 minutes, thereby preparing an enhanced nanoweb. Also provided is a multi-layer article comprising the enhanced nanoweb, and an electrochemical cell comprising the multi-layer article.
