Abstract
The present invention is to provide a method of making a polymer compound material by coating an inorganic material on the surface of a polymer. The method provided by the present invention comprises the step of spraying a high volatile solvent to a chipped polymeric matrix to slightly dissolve the surface of the matrix, and the step of adding inorganic material powders to let the powders be coated on the surface of the matrix layer by layer so as to form the polymer compound material.
Claims18
A method of making a compound precursor adapted to be further used in an injection-molding processing, an extrusion processing or the like, the method comprising the steps of:
- (a) selecting a biodegradable and bioabsorbable polymer material and then forming the selected polymer material into a chipped matrix;
- (b) using a solvent to dissolve the surface of said chipped matrix slightly;
- and
- (c) coating the surface-dissolved chipped matrix with a reinforced filler, thereby forming a heterogeneous precursor.
The method as claimed in one of the claims from 1 through 7, further comprising a drying step of drying the heterogeneous precursor thus obtained.
A method of making a compound precursor comprising the steps of:
- (a) selecting a biodegradable and bioabsorbable polymer material and then forming the selected polymer material into a chipped matrix;
- and
- (b) mixing a reinforced filler in a solvent to form a mixture, and then spraying said mixture onto said chipped matrix to dissolve the surface of said chipped matrix and to let said reinforced filler be coated on the surface of said chipped matrix, thereby forming the precursor.
