Abstract
Disclosed herein is an electrically insulating substrate comprising a p-doped poly(3,4-ethylenedioxythiophene) layer disposed thereon, where the p-doped poly(3,4-ethylenedioxythiophene) layer is manufactured by a method comprising charging a vapor comprising 3,4-ethylenedioxythiophene into a reactor; where the reactor comprises the electrically insulating substrate; charging a vapor comprising an iron salt into the reactor; polymerizing the 3,4-ethylenedioxythiophene with the iron salt to form the p-doped poly(3,4-ethylenedioxythiophene); and disposing the poly(3,4-ethylenedioxythiophene) layer on the substrate.
Claims19
An electrically insulating article comprising:
- a p-doped poly(3,4-ethylenedioxythiophene) layer disposed on an electrically insulating substrate;
- and
- an electrically insulating layer that comprises a gel disposed on the p-doped poly(3,4-ethylenedioxythiophene) layer, where the p-doped poly(3,4-ethylenedioxythiophene) layer is manufactured by a method comprising:
- charging a vapor comprising 3,4-ethylenedioxythiophene into a reactor;
- where the reactor comprises the electrically insulating substrate;
- charging a vapor comprising an iron salt into the reactor;
- polymerizing the 3,4-ethylenedioxythiophene with the iron salt to form the p-doped poly(3,4-ethylenedioxythiophene) layer;
- and
- disposing the p-doped poly(3,4-ethylenedioxythiophene) layer on the electrically insulating substrate;
- and where the p-doped poly(3,4-ethylenedioxythiophene) layer is in direct contact with the electrically insulating substrate and with the electrically insulating layer that comprises the gel.
An article comprising:
- a first electrically insulating substrate upon which is disposed a first p-doped poly(3,4-ethylenedioxythiophene) layer to form a first coated substrate;
- a second electrically insulating substrate upon which is disposed a second p-doped poly(3,4-ethylenedioxythiophene) layer to form a second coated substrate;
- and
- an electrically insulating layer disposed between the first coated substrate and the second coated substrate;
- where the electrically insulating layer prevents electrical communication between the first electrically insulating substrate and the second electrically insulating substrate;
- where the electrically insulating layer comprises a gel;
- where the first p-doped poly(3,4-ethylenedioxythiophene) layer is in direct contact with the first electrically insulating substrate and with the electrically insulating layer;
- and where the second p-doped poly(3,4-ethylenedioxythiophene) layer is in direct contact with the second electrically insulating substrate and with the electrically insulating layer.
A method comprising:
- charging a vapor comprising 3,4-ethylenedioxythiophene into a reactor;
- where the reactor comprises an electrically insulating substrate;
- charging a vapor comprising an iron salt into the reactor;
- polymerizing the 3,4-ethylenedioxythiophene with the iron salt to form a p-doped poly(3,4-ethylenedioxythiophene);
- disposing a p-doped poly(3,4-ethylenedioxythiophene) layer directly on the electrically insulating substrate;
- and
- disposing an electrically insulating layer that comprises a gel directly on the p-doped poly(3,4-ethylenedioxythiophene) layer.
