[0002] The present technology relates to curable silicone - based compositions. In particular, the present technology relates to curable silicone - based compositions comprising an alkenyl - functionalized polymer, a hydride - functionalized polymer, a filler, and a catalyst.

Background Art

[0003] Silicones are known for their inherent properties such as high thermal stability, flexibility, and / or chemical resistance. Based on the above - mentioned properties, siloxanes are used in electronic or electrical applications. Although it may be desirable to use siloxanes in applications where conductivity is important, the development of conductive silicone materials is difficult.

[0004] Electrical properties can be achieved in silicones by adding fillers to the silicone matrix, and the desired conductivity can be achieved by increasing the loading of the filler in the composition. However, at higher loadings, the filler particles can separate from the composition over time. Thus, the dispersion of highly loaded fillers into the siloxane matrix is a major challenge. Higher loading of fillers in the composition can also adversely affect the cure kinetics and processability of the composition. Other common problems include, but are not limited to, variable contact resistance and volume resistivity.

[0005] Efforts have been made to develop curable silicone compositions with desired mechanical and chemical properties to solve these technical problems.

BEST MODE FOR CARRYING OUT THE INVENTION

[0009] In the following specification and the following claims, reference is made to several terms which must be defined to have the following meanings.

[0010] The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. “Optional” or “optionally” means that the subsequent described event or circumstance may or may not occur, and that the description includes examples where the event occurs and examples where it does not.

[0011] The approximating language used throughout this specification and the claims may apply to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by one or more terms such as “about” is not to be limited to the specified exact value. In some instances, the approximating language may correspond to the precision of the instrument for measuring the value.

[0012] As used herein, the terms "aromatic" and "aromatic radical" are used interchangeably and refer to an arrangement of atoms having at least one valence and containing at least one aromatic group. The arrangement of atoms having at least one valence and containing at least one aromatic group may contain heteroatoms such as nitrogen, sulfur, selenium, silicon, and oxygen, or may consist of only carbon and hydrogen. As used herein, the term "aromatic" includes, but is not limited to, phenyl, pyridyl, furanyl, thienyl, naphthyl, phenylene, and biphenyl radicals. As noted above, an aromatic radical contains at least one aromatic group. An aromatic group is always a cyclic structure having 4n + 2 "delocalized" electrons, where "n" is an integer of 1 or greater, such as a phenyl group (n = 1), a thienyl group (n = 1), a furanyl group (n = 1), a naphthyl group (n = 2), an azulenyl group (n = 2), an anthracenyl group (n = 3), etc. An aromatic radical may also contain non-aromatic components.

Similarly, a tetrahydronaphthyl radical is an aromatic radical containing an aromatic group (C6H3) condensed to a non-aromatic component -(CH2)4-. For convenience, the terms "aromatic radical" or "aromatic" are defined herein to encompass a wide range of functional groups such as alkyl groups, alkenyl groups, alkynyl groups, haloalkyl groups, haloaromatic groups, conjugated diene groups, alcohol groups, ether groups, aldehyde groups, ketone groups, carboxylic acid groups, acyl groups (e.g., carboxylic acid derivatives such as esters and amides), amine groups, nitro groups, etc. For example, a 4-methylphenyl radical is a C7 aromatic radical containing a methyl group, and the methyl group is a functional group that is an alkyl group.
