Abstract:
Carbon microspheres(CMSs) is very important one of the carbon funcfional materials, has a unique structure and excellent physical and chemical properties,is a materials science research focus.Carbon microspheres were firstly modified with tetraethyl orthosilicate as precursor to introduce hydroxyl groups onto the surface of CMSs,and then modified by silane coupling agent KH570 to prepare silanizedCMSs,which were the earlier experiment process in synthesize thermosensitive polymers.The morphologies and microstructures of all samples were characterized by field emission scanning electron microscopy,Fourier transformation infrared spectrometry and thermogravimetry.The results indicate that double bands were introduced on the surface of CMSs,which lays an experimental foundation for the functionalization of CMSs.
