Preparation and Characterization of Nano-TiO2/β-CDP Composite
摘要
Abstract
Combining photo-catalysis of nano-titanium dioxide (TiO2)and inclusion property of β-cyclodextrin(β-CD),a nano-TiO2/β-CDP composite with β-CD polymer as the shell and nano-TiO2 as the core was prepared using epichlorohydrin(EPI) as a crosslinking agent.The nano-TiO2/β-CDP composite was characterized with FTIR,UV-Vis,SEM and TGA,and the particle size,β-CD content and stability of its suspension were determined.The results showed that the β-CD content of composite and particle size are affected by the dispersed state of nano-TiO2,and the dosage of β-CD or EPI.Particle size decreased and the β-CD content of the composite increased after ultrasonic processing of nano-TiO2.The particle size increased with the increase ofβ-CD or EPI dosage.The composite retained both the basic structural unit ofβ-CD and the photo-catalytic performance of nano-TiO2.Its UV absorption intensity increased significantly compared with the unmodified nano-TiO2.Moreover,the thermal stability of the composite showed some improvement.关键词
