Surface organo-functionalization of palygorskite nanorods with γ-mercaptopropyltrimethoxysilane
Source abstract
Abstract
Abstract Palygorskite (Pal) nanorods have attracted more and more interests in polymer-based nanocomposites. Surface modification with silane is the main approach to improve their dispersibility in organic matrices. In the present work, the functionalization of Pal nanorods with silane was optimized in detail, aiming to the high dispersibility in organic matrices, including the reaction condition (temperature and time) and feeding ratio of silane (e.g. γ-mercaptopropyltrimethoxysilane, MPS). The morphology of the products was analyzed with TEM technique. Based on the characterization results and the sedimentation phenomena of their dispersions in toluene, the microstructure of the organo-functionalized palygorskite (OPAL) was established, in which locking effect and welding effect of silane were proposed.
