A Novel Preparation Method of Organic-inorganic Aramid Nanofibers (ANFs) Hybrid Membrane Using Ethanol as Proton Donor

LUShengjun

Abstract


In the work, the surface of the titanium dioxide (TiO2) nano particles were modified with 3-Aminopropyltriethoxysilane (KH550) first. And the ANFs were loaded with the different nano TiO2 assisted via the ultrasonic process. Then the organic and inorganic hybrid membrane were fabrication by vacuum assisted flocculation (VAF). Ethanol as a proton donor can realize the flocculation of ANFs. The results of the nanocomposites were characterized by Transmission electron microscope (TEM), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The SEM results indicated that the agglomeration of nanoparticles on ANF were reduced obviously, Through the preparation of aramid nanofiber membrane with the proton donor of ethanol, it is observed that the interlaced network structures of the membrane surface were constructed. The result of the UV data is that the addition of nano-titanium dioxide improves the UV absorption capacity of the fiber membrane.
