AP的结构纳米化及其疏水性能改性
Nano Structuring and Hydrophobic Property Modification of AP
摘要
Abstract
Hydrophobic AP/CBC nanostructured materials were prepared by the solution dipersion-freeze drying method with ammonium perchlo-rate(AP) and carbonized bacterial cellulose(CBC) as raw materials, using polymethylhydrosiloxane (PMHS),dodecafluoroheptylpropyltrimetho-xysilane (FAS) and methyltriethoxysilane (MTES) as modifying agents.The morphology, structure and moisture absorption properties of AP/CBC nanostructured materials were characterized by field emission scanning electron microscopy (FE-SEM), fourier transform infrared spectrometer (FT-IR),X-ray diffractometer (XRD), contact angle tester, constant temperature and humidity box, laser particle size analyzer, contact angle tester and so on.The results show that compared with pure AP, the morphology change of nano-structure materials is larger, and AP is uniformly distributed in the hole of the three-dimensional net-work.Moreover, the surface of the modified nanostructured material after being modified is uniformly coated with modifier, which helps to form a hydrophobic surface.The contact angels of the AP/CBC nanostructured materials modified by PMHS, FAS,MTES are (109±2)°, (56±2)°, (55±2)°, respectively, which are greatly improved compared with pure AP.The modified AP/CBC nanostructured materials have lower moisture absorption than the pure AP, especially the AP/CBC nanostructured materials modified by PMHS have the lowest moisture absorption of 0.31%.关键词
