Comparison of CNT assembly structure for different films.
(a) CNT aggregation in the layer-by-layer stacking of array-drawn CNT sheets. (b) CNT aggregation in the stretched dry films composed by entangled CNTs. (c) The small-sized CNT bundles did not aggregate but were surrounded by BMI polymers and uniformly distributed. (d,e) 750 °C treated CNT/BMI composite films where the stretching of 21% and 27% was performed before and after resin impregnation, respectively. (f) Cross section of the optimal CNT/BMI composite structure by using focused ion beam treatment.
