Abstract

The following data provide evidence of the green functionalization process of a cellulose substrate by gamma radiation to be used as template in the preparation of photocatalyst composites. Functionalized cellulose, by gamma radiation treatment, improved its stability in water and exhibited a reduced size. Our data showed an intensification of carbonyl groups signal and a decrease in the thermal stability of the cellulose as result of the gamma radiation dose. Infrared and thermal data of the treated cellulose provide evidence of bond scission and the formation of functional groups that improved it is application as template. Finally, the conductive polymer poly(3,4-ethylenedioxythiophene) was deposited on the gamma irradiated cellulose to be used as photo-catalyze in the treatment of contaminated water with pharmaceutical compounds.

摘要

以下数据证明了通过γ辐射对纤维素基材进行绿色功能化处理的过程，该纤维素基材将用作制备光催化剂复合材料的模板。经γ辐射处理的功能化纤维素提高了其在水中的稳定性，并呈现出减小的尺寸。我们的数据表明，由于γ辐射剂量的原因，纤维素的羰基信号增强，热稳定性降低。处理后纤维素的红外和热数据证明了键的断裂以及官能团的形成，这改善了其作为模板的应用。最后，将导电聚合物聚（3,4-亚乙基二氧噻吩）沉积在经γ辐射的纤维素上，用作处理含药物化合物的污水的光催化剂。
