Abstract
Abstract Method and apparatus for producing an electrical conductor are provided comprising a doped polymeric material and an encasement means substantially impermeable to the dopant, the encasement means having matching surfaces in contact with the polymeric material to reduce the loss of dopant and an inert gas to occupy any voids between the surfaces.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A method of producing an electrical conductor which comprises: a. treating a polymeric material with a dopant to make the material electrically conductive; b. locating said polymeric material in an encasment comprised of a pair of ribbon-like members having planar opposed matching surfaces, said encasement being substantially electrically non-conductive and substantially impermeable to said dopant, said polymeric material being positioned between the matching surfaces in contact with each of said surfaces effective to substantially reduce the loss of dopant from said polymeric material; c. extending electrical conducting means in contact with said polymeric material to the exterior of the encasement; d. filling any space between the matching surfaces not occupied by the polymeric material with an inert gas; and e. sealing said encasement around the edges thereof to retain said inert gas in said encasement.
Claim 2
Independent Claim
135 words
A method of producing an electrical conductor which comprises: a. treating a polymeric material with a dopant to make the material electrically conductive; b. locating said polymeric material in an encasment comprised of a pair of ribbon-like members having planar opposed matching surfaces, said encasement being substantially electrically non-conductive and substantially impermeable to said dopant, said polymeric material being positioned between the matching surfaces in contact with each of said surfaces effective to substantially reduce the loss of dopant from said polymeric material; c. extending electrical conducting means in contact with said polymeric material to the exterior of the encasement; d. filling any space between the matching surfaces not occupied by the polymeric material with an inert gas; and e. sealing said encasement around the edges thereof to retain said inert gas in said encasement.
Claim 3
Dependent Claim
20 words
The method of claim 1 wherein said encasement is selected from the group consisting of polymers, glass, diamond and mica.
Claim 4
Dependent Claim
19 words
The method of claim 1 in which said film is encased in glass ribbons about 0.005 cm in thickness.
Claim 5
Dependent Claim
19 words
The method of claim 1 in which said material is positioned in a plurality of rows within said encasement.
Claim 6
Dependent Claim
125 words
An electrical conductor comprising; a. a polymeric material containing a dopant to make the material electrically conductive; b. an encasement comprised of a pair of ribbon-like members having planar, opposed matching surfaces, said encasement being substantially electrically non-conductive and substantially impermeable to said dopant, said polymeric material being positioned between the matching surfaces in contact with each of said surfaces effective to substantially reduce the loss of dopant from said polymeric material; c. electrical conductor means in contact with the polymeric material and extending to the exterior of the encasement; and d. an inert gas to fill any space between the matching surfaces not occupied by the polymeric material, said encasement being sealed around the edges thereof to retain said inert gas in said encasement.
Claim 7
Dependent Claim
125 words
An electrical conductor comprising; a. a polymeric material containing a dopant to make the material electrically conductive; b. an encasement comprised of a pair of ribbon-like members having planar, opposed matching surfaces, said encasement being substantially electrically non-conductive and substantially impermeable to said dopant, said polymeric material being positioned between the matching surfaces in contact with each of said surfaces effective to substantially reduce the loss of dopant from said polymeric material; c. electrical conductor means in contact with the polymeric material and extending to the exterior of the encasement; and d. an inert gas to fill any space between the matching surfaces not occupied by the polymeric material, said encasement being sealed around the edges thereof to retain said inert gas in said encasement.
Claim 8
Dependent Claim
22 words
The conductor of claim 5 in which said encasement material is selected from the group consisting of polymers, glass, diamonds and mica.
Claim 9
Dependent Claim
28 words
The conductor of claim 5 in which said encasement is filled with an inert gas within the range of from about 755 to about 765 mm Hg, absolute.
Claim 10
Dependent Claim
17 words
The conductor of claim 5 in which said encasement comprises glass ribbons about 0.005 cm in thickness.
Claim 11
Dependent Claim
18 words
The conductor of claim 5 in which said a plurality of said materials are positioned within said encasement.
