| Abstract: | In this study, the preparation, properties, and characterization of thin films or “nanopapers” of carbon nanofibers (CNFs) were studied. Specifically, a layer-by-layer nanopaper preparation method was used, which significantly improved the mechanical properties of nanopapers. The effect of CNF nanopaper on the cure kinetics of a low temperature epoxy resin was studied. A modified autocatalytic model was used to represent the reaction kinetics. It was found that the presence of CNF nanopaper substantially increased the resin reaction rate and final conversion. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012 |
