Abstract

A wood-based panel includes at least one carrier board and at least one resin layer disposed side of the board. The at least one resin layer includes carbon-based particles, at least one compound of the formula R1aR2bSiX(4-a-b), and/or hydrolysis products. X is H, OH, or a hydrolysable moiety selected from the group including halogen, alkoxy, carboxyl, amino, monoalkylamino or dialkylamino, aryloxy, acyloxy, and alkylcarbonyl. R1 is an organic residue selected from the group including alkyl, aryl, and cycloalkyl, which may be interrupted by —O— or —NH—. R1 has at least one functional group Q1 selected from a group containing a hydroxy-, amino, monoalkylamino, carboxy, mercapto, alkoxy, aldehyde, acrylic, acryloxy, methacrylic, methacryloxy, cyano, isocyano and epoxide group, R2 is a non-hydrolyzable organic moiety selected from the group including alkyl, aryl, alkenyl, alkynyl, cycloalkyl, and cycloalkenyl; A is 0, 1, 2, or 3. B is 1, 2, 3, or 4.
