Hexamethylene diisocianate hdi

Orgacon ™ DRY, grey-blue re-dispersible pellets of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS ratio of 1:2.5, d_25°C = 1.911 g/cm³), triethylamine (TEA, >98%, M_w = 101.193 g/mol), H₂SO₄, KMnO₄, P₂O₅, K₂S₂O₈, and H₂O₂ (30 wt % in water) were obtained from Sigma-Aldrich (Madrid, Spain) and used as received. Graphite powder was purchased from Bay Carbon, Inc. (Bay City, MI, USA). Hexamethylene diisocianate (HDI, >99%, M_w = 168.196 g/mol) was provided by Acros Organics (Madrid, Spain). All the organic solvents were HPLC grade and were purchased from Scharlau S.L. (Barcelona, Spain).

Aniline monomer (C₆H₅NH₂, >99%, M_w = 93.13 g/mol, d_25ºC = 1.02 g/cm³), ammonium persulfate ((NH₄)₂S₂O₈, 98%, M_w = 228.20 g/mol, d_25ºC = 1.98 g/cm³), triethylamine (TEA, >98%, M_w = 101.193 g/mol), H₂SO₄, KMnO₄, P₂O₅, K₂S₂O₈ and H₂O₂ (30 wt % in water) were obtained from Sigma-Aldrich (Madrid, Spain). Graphite powder was purchased from Bay Carbon, Inc. (Bay City, MI, USA). Hexamethylene diisocianate (HDI, >99%, M_w = 168.196 g/mol) was provided by Acros Organics (Madrid, Spain). The organic solvents were HPLC grade and were purchased from Scharlau S.L. (Barcelona, Spain). Deionized water was obtained from a Milli-Q-Water-Purification-System (Millipore, Milford, DE, USA). Aniline was stored in a refrigerator and was distilled under reduced pressure prior to use; the rest of the chemicals were used as received.
