超微细气相法白炭黑的表面改性

气相法白炭黑是重要的高科技超微细无机新材料之一。然而， 呈亲水性的表面硅醇基结构使其在某些疏水领域的应用受到限制。为进一步改善其性能和拓宽其应用领域， 人们对其表面结构和性质进行了大量卓有成效的改性研究。本文综述了近几年来气相法白炭黑表面活性的研究成果和工业化技术

SURFACE MODIFICATION OF THE ULTRAFINE FUMED SILICA

Although fumed silica is one of the most important sophisticated ultrafine inorganic new material,its hydrophilic surface silanols restrict its application used as hydrophobic product in some fields.In order to improve its properties and enlarge its application fields,the researchers had already done a lot of fruitful work in the modification of the surface structure and the property of silica.This essay expounded on the subject of the research findings and the industrialized technologies of the surface modification of silica in recent years.
