An impregnate with antistatic properties for use in laminates or for coating wood-based panels is disclosed. A resin used for impregnating and/or coating paper may include carbon-based particles, at least one compound of the general formula (Ia) R.sup.1.sub.aSiX.sub.(4-a), R.sup.3.sub.cSiX.sub.(4-c) (II), and inorganic particles. X is methoxy, ethoxy, n-propoxy or i-propoxy. R.sup.1 is an organic radical selected from the group including methyl, ethyl, propyl, or vinyl, and has at least one functional group Q.sub.1, selected from the group including acrylic, acryloxy, methacrylic, methacyloxy, or epoxy. R.sup.3 is a non-hydrolyzable organic radical selected from the group including C1-C10 alky, C6-10 aryl, wherein C is 1, 2, or 3, and the inorganic particles have a size between 2 nm and 400 nm.

In the porous substrate loaded with porous nano-particles structure and one-step micro-plasma production method thereof, since the micro-plasma system enhances the electron density and promotes reaction speed in the reaction without generating thermal effect, the method may be performed at an atmosphere environment. The nano-particles also can be quickly obtained by aforementioned micro-plasma system. The electromagnetic field generated by the micro-plasma can drive the nano-particles to be loaded onto the porous substrate in a one step, rapid and low cost process to improve the conventional techniques which require a relatively long procedure time and a complicated process.
