A method of surface modifying a polyimide film, a method of manufacturing a flexible copper clad laminate using the same, and a flexible copper clad laminate (FCCL) having a two-layer structure manufactured thereby. The method of surface modifying a polyimide film is conducted by modifying the surface of a polyimide film through a first plasma treatment, dipping the polyimide film into a solution containing an ethyleneimine-based silane coupling agent prepared by mixing the compound of Formula 1 and the compound of Formula 2 at a molar ratio of with 0.25˜1, and then modifying the surface of the polyimide film through a second plasma treatment. The method of surface modifying a polyimide film is advantageous because it may be substituted for a conventional surface treatment processes using ion beams. Also, the FCCL having a two-layer structure, formed by conducting copper sputtering and electroplating on the surface modified polyimide film, has good adhesive strength between the polyimide film and the copper foil and can maintain such adhesive strength even at high temperatures for a long period of time. Further, it may be usefully applied to electronic parts, such as flexible printed circuit boards, TCP (Tape Carrier Package), COF (Chip On Film), etc.

The present invention provides organic-inorganic composite particles containing metal complexes, which have multiple needle-like structures on the surface and contain metal complexes; and a simple manufacturing method of the particles. This can be achieved by inducing a metal complex composed of a polymer having a linear polyethyleneimine skeleton and a metal ion to induce composite particles with a fine needle-like surface containing the metal complex inside the silica. Needle-shaped surface particles with multiple nanoscale needle-like structures on the surface of the particles. The needle-like structure of the resulting needle-shaped surface particles and the spatial structure of the particles can be controlled by changing the metal ion species and the metal complex support medium.
