Abstract:
This invention relates to a resin composition with good workability, including a liquid crystal oligomer, an epoxy resin, or a resin mixture thereof, and an inorganic filler having a nanocone shape, and to an insulating film for a printed circuit board, and a prepreg, which are manufactured using the resin composition.
Abstract:
Disclosed herein is a method of preparing a surface-modified inorganic filler, comprising the steps of: drying an inorganic filler; treating the inorganic filler with fluorine-containing gas to bond fluorine (F) to a part of the surface of the inorganic filler; and bonding a functional group-bonded silane coupling agent to another part of the surface of the inorganic filler, this other part of the surface thereof being not bonded with fluorine.
