Owing　to　their　unique　structure　and　properties,　carbon　nanotubes　(CNTs)　have　become　the　highlight　of　research　since　they　were　discovered.　Part　of　the　research　interest　lies　in　introducing　them　into　solid　state　matrix　to　make　them　materialized.　However,　CNTs　tend　to　aggregate　in　the　matrix,　which　makes　it　difficult　to　make　homogeneous　composites.　In　order　to　solve　this　problem,　we　first　modified　the　surface　of　CNTs　by　chemically　bonding　them　to　3-aminopropyltrie-thoxysilane　(NH2　(CH2)(3)Si(OC2H5)(3),　APTES)　using　three-step　reactions,　and　then　connected　them　to　silica　network　by　sol-gel　technique.　In　the　present　paper,　CNTs　were　first　treated　with　HNO3　to　get　CNTs-COOH,　which　were　then　treated　with　SOCl2　to　be　transferred　to　CNTs-COCl,　and　finally　CNTs-COCl　reacted　with　APTES　to　got　CNTs-APTES.　After　that,　CNTs　were　introduced　into　silica　net　work　through　the　individual　hydrolysis　of　CNTs-APTES,　tetrathyloxysilane　(Si(OC2H5)(4),　TEOS)　and　3-glycidoxy-propltrimethoxysilane　(CH2OCHCH2O(CH2)(3)Si(OCH3)(3),　GPTMS)　as　sol-gel　precursors,　and　the　copolymerization　of　their　hydrolysis　products.　FTIR　and　SEM　were　used　to　characterize　the　composition　and　microstructure　Of　the　obtained　samples.　Owing　to　the　connection　of　CNTs　with　silica　network,　little　aggregation　of　CNTs　was　observed　and　high-quality　CNTs/SiO2　composite　gel　glass　was　obtained.　A　model　of　CNTs/SiO2　network　was　also　given.
