Thermal interface material

A composite material comprising a thermally conductive component in the form of a sheet that is coated with a surface modified nitride, wherein the nitride is surface modified with at least one silane compound having the following formula (I):

• R1—(X1)m—(CR3R4)m—Si(—O—R2)3 (I)
• wherein R1 is selected from the group consisting of halogen, thiol, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted amino, optionally substituted hydroxylalkyl, optionally substituted acylamino, optionally substituted acyloxy, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted heterocycloalkyl, optionally substituted heterocycloalkenyl and —(C(X2)2)y;
• each occurrence of R2 is independently selected from the group consisting of hydrogen, optionally substituted alkyl and silane ester;
• each occurrence of R3 and R4 are independently hydrogen or optionally substituted alkyl;
• each occurrence of X1 or X2 are linkers independently selected from the group consisting of a bond, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted heteroalkyl, optionally substituted heteroalkenly, optionally substituted heteroalkynyl, optionally substituted alkyloxy, optionally substituted alkenyloxy, optionally substituted alkynyloxy, optionally substituted acyloxy, optionally substituted amino and optionally substituted acylamino;
• m and n are independently any integer from 0 to 6;
• and
• y is any integer from 1 to 200.
