Claims24
A dielectric composition comprising the condensation product of a polymeric component selected from a poly(vinylphenol), a copolymer of a poly(vinylphenol), a poly(vinylalcohol), a copolymer of a poly(vinylalcohol), and combinations thereof;
- and a bis(silyl)alkyl component of the formula (X)3-m(Y)mSi(Z)Si(Y′)m′(X′)3-m′, wherein Z is a moiety selected from (CH2)n, a divalent branched alkyl group, and a divalent substituted alkyl group;
- n ranges from 1 to 20;
- X and X′ are independently selected from halide, amino, alkoxy and carboxylate groups, and combinations thereof;
- Y and Y′ are independently selected from H and alkyl;
- and m and m′ independently range from 0 to 2.
A dielectric composition comprising the condensation product of a polymeric component selected from a poly(vinylphenol), a copolymer of a poly(vinylphenol), a poly(vinylalcohol) and a copolymer of a poly(vinylalcohol) and combinations thereof and a bis(silylated) component of the formula (X)3-m(Y)mSi(Z)Si(Y′)m′(X′)3-m′, wherein Z is a moiety selected from O, (CH2)n, a divalent branched alkyl group, and a divalent substituted alkyl group;
- n ranges from 1 to 20;
- X and X′ are independently selected from halide and amino groups, and combinations thereof;
- Y and Y′ are independently selected from H and alkyl;
- and m and m′ independently range from 0 to 2.
A dielectric film comprising the condensation product of a polymeric component selected from a poly(vinylphenol), a copolymer of a poly(vinylphenol), a poly(vinylalcohol), a copolyrner of a poly(vinylalcohol), and combinations thereof;
- and a bis(silylated) component of the formula (X)3-m(Y)mSi(Z)Si(Y′)m′(X′)3-m′, wherein Z is a moiety selected from O, (CH2)n, a divalent branched alkyl group, and a divalent substituted alkyl group;
- n ranges from 1 to 20;
- X and X′ are independently selected from halide, amino, alkoxy and carboxylate groups, and combinations thereof Y and Y′ are independently selected from H and alkyl;
- and m and m′ independently range from 0 to 2;
- wherein the dielectric film has a thickness between about 10 nm and about 30 nm, and exhibits a capacitance of at least about 150 nF cm−2.
