Patent ID: 7614293

Claim:
A method of evaluating an adhesion property comprising the steps of: calculating a value of field strength of each of a plurality of oxides, where said value of field strength of each of said plurality of oxides is a value obtained by dividing a valence of a metal cation contained in one oxide of said plurality of oxides by a square of a sum of an ionic radius of said metal cation and an ionic radius of an anion contained in said one oxide; measuring a value of adhesion strength between each of said plurality of oxides and an organic substance by experiment; graphically representing a corresponding relationship between the value of field strength and the value of adhesion strength for each of said plurality of oxides; determining a reference value for comparison of an adhesion property in said corresponding relationship; calculating a value of field strength of another oxide, said value of field strength of another oxide being a value obtained by dividing said valence of said metal cation contained in said another oxide by a square of a sum of an ionic radius of said metal cation and an ionic radius of an anion contained in said another oxide; and evaluating an adhesion property of said another oxide by comparing said value of field strength of another oxide with said reference value for comparison.
