    摘要： A nanoweb that contains a plurality of nanofibers wherein the nanofibers contain a fully aromatic polyimide that is characterized by having a crystallinity index (CI) and a degree of imidization (DOI). The product of the DOI and the CI is between 0.08 and 0.25 or above a lower limit to obtain a desired tensile strength and/or toughness. The nanoweb may for example have a tensile strength per unit basis weight of greater than 15 kg/cm2 per gram per square meter unit of basis weight.
