Electrically conductive polymer materials, such as mixtures of poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(styrenesulfonate) (PSS) are combined with functionalized carbon nanotubes to form composites that exhibit increased electrical conductivity. Functionalized or non-functionalized carbon nanotubes combined with the same electrically conductive polymer materials are combined with non-conductive polymers to increase the electrical conductivity of the non-conductive polymer. The functionalized carbon nanotubes are functionalized with carboxyl and/or hydroxyl groups. The resulting materials are useful in methods of forming electrically conductive films and electrically conductive features.

Maleate polyester polyols and coatings made from the polyols are disclosed. The polyester polyols comprise recurring units of (a) a digested thermoplastic polyester or an aromatic dicarboxylate source; (b) a diol; (c) 5 to 95 mole % of an α,β-unsaturated monomer; and (d) 5 to 95 mole % of adipic acid, succinic acid, or a mixture thereof, where the mole % ranges for (c) and (d) are based on the combined molar amounts of (c) and (d). The polyols have hydroxyl numbers within the range of 25 to 450 mg KOH/g, an average of 0.5 to 2.5 reactive unsaturation sites per molecule, and a viscosity less than 1500 cP at 75° C. The polyols are thermally curable or energy-curable. Coatings made from the maleate polyester polyols are also described. Traditional coatings based on polyisocyanates and/or (meth)acrylates can be made, in some cases with improved properties and reduced reliance on the acrylate or isocyanate-based components. Surprisingly, the maleate polyester polyols can also be cured directly using UV to produce coatings under ambient conditions without the need for either acrylic or isocyanate functionality, and this allows coating formulators to reduce cost and more easily achieve regulatory compliance without sacrificing important coating properties. Rigid polyisocyanurate and polyurethane foams produced from the maleate polyester polyols have improved fire retardance. 1. A polyester polyol comprising recurring units of:(a) a digested thermoplastic polyester;(b) a diol;(c) 5 to 95 mole % of an α,β-unsaturated monomer; and(d) 5 to 95 mole % of adipic acid, succinic acid, or a mixture thereof;wherein the mole % ranges for (c) and (d) are based on the combined molar amounts of (c) and (d);wherein the polyol has a hydroxyl number within the range of 25 to 450 mg KOH/g, an average of 0.5 to 2.5 reactive unsaturation sites per molecule, and a viscosity less than 1500 cP at 75° C.; andwherein the polyol is thermally curable or energy-curable.2.
