Nanostructured thermoplastic polyimide films
Abstract
Structured films containing multi-walled carbon nanotubes (“MWCNTs”) have enhanced mechanical performance in terms of strength, fracture resistance, and creep recovery of polyimide (“PI”) films. Preferably, the loadings of MWCNTs can be in the range of 0.1 wt % to 0.5 wt %. The strength of the new PI films dried at 60° C. increased by 55% and 72% for 0.1 wt % MWCNT and 0.5 wt % MWCNT loadings, respectively, while the fracture resistance increased by 23% for the 0.1 wt % MWCNTs and then decreases at a loading of 0.5 wt % MWCNTs. The films can be advantageously be created by managing a corresponding shift in the annealing temperature at which the maximum strength occurs as the MWCNT loadings increase.
