Abstract
A method of fabricating a structure comprising the steps of: providing an electrical conductor; providing a layer of a flexible insulating material on the electrical conductor, the material comprising: a first organo-alkoxide 1RxSi(O1R′)4-x and a second organo-alkoxide 2RxSi(O2R′)4-x, where 1R is a non-hydrolysable organic moiety thermally stable to a temperature of at least 150° C., 2R is a non-hydrolysable organic moiety containing a functional group that can react with another like functional group to form an organic polymer, 1R′ and 2R′ are alkyl radicals and x is an integer from 0 to 3; and an inorganic filler material.

A method of fabricating an electrical conductor having an insulating coating, the method including the steps of:
- providing the electrical conductor;
- coating the electrical conductor with at least one layer of a flexible insulating percursor material on the electrical conductor, the percursor material comprising:
- a first organo-alkoxide 1RxSi(O1R′)4-x, a second organo-alkoxide 2RxSi(O2Ryx and an inorganic filler material, where 1R is a non-hydrolysable organic moiety thermally stable to a temperature of at least 150° C., 2R is a non-hydrolysable organic moiety containing a functional group that can react with another like functional group to form an organic polymer1, wherein R′ and 2R′ are alkyl radicals and x is 1 or 2.
A percursor structure for an electrical conductor having an insulating coating comprising:
- an electrical conductor;
- at least one layer of a flexible insulating precursor material above the electrical conductor, the percursor material comprising:
- a first organo-alkoxide 1RxSi(O1R′)4-x, a second organo-alkoxide 2RxSi(O2R)4-x and an inorganic filler material where 1R is a non-hydrolysable organic moiety thermally stable to a temperature of at least 150° C., 2R is a non-hydrolysable organic moiety containing a functional group that can react with another like functional group to form an organic polymer, 1R′ and 2R′ are alkyl radicals and x is 1 or 2.
A structure comprising an electrical conductor having a layer of an insulating material provided thereon, the insulating layer comprising inorganic filler particles bound together by means of a SiO2 based binder material derived from decomposition of organo-alkoxides according to a reaction of the form
- ARSiO3Z2+BO2→CSiO2+DH2O+ECO2
- or similar, where A, B, C, D and E depend on the nature of the organic precursor R.
