Lack of matrix dispersion is one principle reason why single‐walled carbon nanotube (SWNT) composites have not yielded the enormous enhancement of mechanical properties predicted by theory. Non‐destructive methods for gauging matrix dispersion, using near‐IR fluorescence are reported (see Figure), along with new materials and processes that exhibit individual, SWNT dispersion in a matrix at relatively high loading (up to 20 vol.‐%).
