Description of samples used in this study

Samples	Description
PAN	The control PAN film obtained from 10% PAN solution in DMF
MS	SWCNH/PAN composite film; (0.5% carbon nanohorns in 10% PAN solution) suspension sonicated in the PAN solution only
SU10	SWCNH/PAN composite film (0.5% carbon nanohorns in 10% PAN solution)—gradual sonication, first in DMF and then in the PAN solution
SU10t	SWCNH/PAN composite film (0.5% carbon nanohorns in 10% PAN solution)—gradual sonication in DMF with 1% surfactant and then in the PAN solution
SU10a	SWCNH/PAN composite film (1% carbon nanohorns in 10% PAN solution)—gradual sonication in DMF and then in the PAN solution
SU10b	SWCNH/PAN composite film (3% carbon nanohorns in 10% PAN solution)—gradual sonication in DMF and then in the PAN solution
SU10at	SWCNH/PAN composite film (1% carbon nanohorns in 10% PAN solution)—gradual sonication in DMF with 1% surfactant and then in PAN solution
