Abstract: Fumed silica is modified by 3-chloropropyl trimethoxysilane and its derivative quaternary ammonium salt to obtain a series of modified nano silica particles coupling with siloxane with different chain length.The surface properties and foam properties of modified nano silica particles are studied.The results show that the modified nano silica particles have better dispersion properties than before modification.The dynamic light scattering (DLS) results show that the size of agglomeration decreases to 255 nm from 459 nm for unmodified one.The water contact angles experiment discloses that the contact angle is related to the carbon chains length of silane coupling agent.Meanwhile,the particles with a contact angle close to 90° can bring to a better foam stabilization efficiency to lauryl propyl betaine and has a stronger ability to cut down surface tension of foaming agent solution.
