TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The CNT or the graphene comprising structure comprises several CNTs or several graphene comprising structures, where the polymer supramolecular structures non-covalently couple and electrically couple at least a portion of respective ones of several CNTs or graphene comprising structures together. The graphene comprising structure comprises pristine graphene, chemically derived graphene, reduced graphene oxide or graphite oxide in a form of nanosheets. The CNT or graphene comprising polymer composite includes CNT or graphene comprising outer surface, and several crystalline polymer supramolecular structures. Preferred Method: The method further comprises casting the dispersion on a substrate before the evaporating step.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The conjugated polymer comprises a conjugated homopolymer or block copolymer comprising at least a lock of the conjugated polymer and at least a block of a non-conjugated polymer. The polymer supramolecular structures comprise nanocolumns, nanoribbons or nanofibers. The conjugated polymer comprises poly(3-hexylthiophene) and the graphene comprising structure comprises reduced graphene oxide (RGO) monolayers, where, following the evaporating step, the poly(3-hexylthiophene) forms nanowires that grow from the RGO monolayers, and connect respective ones of the RGO monolayers. EXAMPLE - Dispersed multi-walled carbon nanotubes (MWCNTs) chloroform solution (0.05 ml) comprising MWCNTs (0.8 mg/ml) and P3HT (poly(3-hexylthiophene))-b-polystyrene (0.7 mg/ml) was added to P3HT hot cyclopentanone solution (0.12 mg/ml, 80 degrees C). The mixture was cooled down to room temperature at 25 degrees C/hour. The obtained dispersions were characterized without further purification. During cooling, P3HT started to form crystals due to the strong pi - pi interaction between the P3HT-b-polystyrene on MWCNTs and P3HT to give series of supramolecular structures.
