Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
84 words
A method for making an ionic/electronic composite conductor which comprises: (i) preparing in a common solvent or solvent mixture a solution of an ionic conducting material and an electronic conducting material, (ii) Intimately mixing the solution, (iii) casting the solution on a substrate, (iv) removing the solvent, and (v) obtaining a continuous coherent film of a continuous electronic conducting material intimately mixed with a continuous ionic conducting material such that the ionic conducting material has an increased melting point over its normal melting point.
Claim 2
Independent Claim
84 words
A method for making an ionic/electronic composite conductor which comprises: (i) preparing in a common solvent or solvent mixture a solution of an ionic conducting material and an electronic conducting material, (ii) Intimately mixing the solution, (iii) casting the solution on a substrate, (iv) removing the solvent, and (v) obtaining a continuous coherent film of a continuous electronic conducting material intimately mixed with a continuous ionic conducting material such that the ionic conducting material has an increased melting point over its normal melting point.
Claim 3
Dependent Claim
36 words
The method of claim 1 wherein the electronic conducting material is obtained from a precursor by transforming the precursor into an electronic conducting material after step (iv) by heating the precursor at temperatures below 130° C.
Claim 4
Dependent Claim
33 words
The method of claim 2 wherein the ionic conducting material is a polyalkylene oxide containing a ionic salt and the precursor electronic conducting material is a polymer of 7,8-bis(trifluoromethyl) tricyclo-[4,2,3,0 2 ,5 ]-deca-3,7,9-triene.
