Abstract
Electrostatic dissipation coatings based on regioregular polythiophenes including blends and block copolymers. The compositions can be soluble in organic solvents. Excellent film formation, transparency, stability, and conductivity control can be achieved.
Claims21
An article comprising:
- at least one substrate,
- at least one electrostatic dissipation coating on the substrate, wherein the coating comprises at least one polymer blend comprising at least one polymer comprising regioregular polythiophene and at least one polymer which does not comprise regioregular polythiophene, wherein the coating transparency is at least 80% for a coating thickness of 38 nm.
An article comprising:
- at least one substrate,
- at least one electrostatic dissipation coating on the substrate having a coating thickness of about 100 nm or less, wherein the coating comprises (1) at least one polymer blend comprising at least one polymer comprising an organic solvent soluble regioregular polythiophene which is doped, and (2) at least one organic solvent soluble polymer which does not comprise regioregular polythiophene, wherein the coating transparency is at least 80% for a coating thickness of 38 nm.
An article comprising:
- at least one substrate,
- at least one electrostatic dissipation coating on the substrate, wherein the coating comprises at least one polymer comprising regioregular polythiophene and the coating, wherein the coating transparency is at least 80% for a coating thickness of 38 nm.
