| 摘 要： | 利用旋涂法，通过接枝共聚方法制备具有偶氮侧基的聚氨酯高分子聚合物薄膜。利用二倍频YAG激光(532nm)作为激发光，白光光源作为参考光，在室温下测试了该薄膜在激发光作用前后的吸收光谱，发现该薄膜在430一530nm内有较强的吸收。最后给出激发光强度的增大和撤去激发光后，随着无光照时间的延长，380nm与520nm波长处吸收强度的变化趋势。 |

EXPERIMENT STUDY ON OPTICAL RECORDING MATERIAL OF AZOBENZENCE COPOLYMER THIN FILMS BY GRAFT-COPOLYMERIZATION |
|
| Abstract: | In this paper, with the spin coating, the azobenzence side chain polymer copolymer thin film has been made by the graft copolymerization method. At room temperature, using the 532 nm light as the exciting light and the white light as the reference light, the absorption spectra of the film before and after irradiation are obtained. The results show that the copolymer film has spectrum response in the broad region of 350-600 nm, especially a strong and broad absorption at the region of 430-530 nm. With the intensity of 532 nm laser increasing, the variable curves of the absorbance at 380 nm and 520 nm are achieved. After shutting the laser, the same tendency, as the time goes on, is obtained. |
