【摘要】：以高氯酸銨(AP)和碳化細(xì)菌纖維素(CBC)為原料,并以聚甲基氫基硅氧烷(PMHS)、十二氟庚基丙基三甲氧基硅烷(FAS)和甲基三乙氧基硅烷(MTES)為表面改性劑,采用溶液分散-冷凍干燥法制備疏水AP/CBC納米結(jié)構(gòu)材料。通過場發(fā)射掃描電子顯微鏡、紅外光譜儀、X射線衍射儀、恒溫恒濕箱、激光粒度分析儀、接觸角測試儀等分別表征了AP/CBC納米結(jié)構(gòu)材料的微觀形貌、分子結(jié)構(gòu)、吸濕性能。結(jié)果表明,與純AP相比,AP/CBC納米結(jié)構(gòu)材料的形貌變化較大,AP均勻分布在三維網(wǎng)絡(luò)孔洞中,并且改性后的AP/CBC納米結(jié)構(gòu)材料表面被改性劑均勻包覆,這有助于疏水表面的形成。經(jīng)過PMHS、FAS、MTES改性后的AP/CBC納米結(jié)構(gòu)材料的接觸角分別為(109±2)°、(56±2)°、(55±2)°,與純AP相比有很大的提高。經(jīng)過改性處理的AP/CBC納米結(jié)構(gòu)材料吸濕性均小于純AP,且經(jīng)過PMHS改性的AP/CBC納米結(jié)構(gòu)材料的吸濕性最低,僅為0.31%。
[Abstract]:Ammonium perchlorate (AP) and carbonated bacterial cellulose (CBC) were used as raw materials, and polymethylhydrosiloxane (PMHSN), 12 fluoroheptyl propyl trimethoxysilane (FASS) and methyl triethoxysilane (MTESs) were used as surface modifiers. Hydrophobic AP/CBC nanostructured materials were prepared by solution dispersion and freeze-drying method. Field emission scanning electron microscopy (SEM), infrared spectrometer (IR) and X-ray diffractometer (XRD), constant temperature and humidity box, laser particle size analyzer (LPA) were used. The micromorphology, molecular structure and hygroscopicity of AP/CBC nanostructured materials were characterized by contact angle tester. The results showed that the morphology of AP / CBC nanostructured materials varied greatly compared with pure AP. And the surface of modified AP/CBC nanostructure material is uniformly coated with modifier. The contact angle of the modified AP/CBC nanostructured materials is 55 鹵2 擄, which is much higher than that of the pure AP. The modified AP/CBC nanostructure materials have less moisture absorption than the pure APs, and the modified AP/CBC nanostructure materials have less moisture absorption than the pure APs materials, and the contact angles of the modified AP/CBC nanostructure materials are 56 鹵2 擄and 55 鹵2 擄respectively, which are much higher than that of the pure AP materials, and the modified AP/CBC nanostructure materials are less hygroscopicity than the pure APs materials. The hygroscopicity of AP/CBC nanostructures modified by PMHS was the lowest. Only 0.31.
