The acrylic thin film modified with methoxysilane containing PAG was formed on a glass substrate and irradiated with ultraviolet rays to promote sol-gel reaction by catalytic action of acid which was generated from PAG. And then the film was hardened with microwave irradiation, yielding organic-inorganic hybrid polymer film having hardness, highly transparency and strong adhesion with a glass substrate. Since this reaction only occurred in the optically (UV) irradiated regions, by exploiting the difference between the adhesivenesses of these regions photo-irradiated through photomask with a glass substrate, it was possible to form a patterned film with pitch of 100 to 50 μm by a simple lift-off method. A pigment-containing film using latent pigments (with subtractive three primary colors of coloring materials) and a patterned film were prepared, and it was possible to make these films multi-colored by varying the mixing ratio of the pigments. This multi-colored film-preparation method is effective for simply and efficiently forming a color-filter film by applying optical and microwave irradiation.展开更多

The optimal conditions for phenol-sulfuric acid colorimetric method to determine the content of Jinggan^nyein were as follows: anhydrous glucose as control sample, 5% phenol, 1.0 ml phenol solution, 5.0 nfl sulfuric acid, stilly placed for20 min after reaction, 490 nm as detec- tion wavelength; the correlation coefficient of glucose standard curve ( R2 ) was 0. 993 9; the average recovery of standard addition was 99.72%, RSD was 0. 362 8%. ~ Conclusion] Re-cryatallization is a good way to refine Jinggan^nycin. Phenol-sulfuric acid colorimetric method can be used to determine the content of Jinggangmycin with simple operation, high accuracy and strong reliability, which can be widely applied in industrial production.展开更多
