Surface modification of muitiwalled carbon nanotubes via esterification using a biodegradable polyol
Multiwalled carbon nanotubes (MWCNT) were surface modified firstly oxidizing them with a H 2SO 4/HNO 3 mixture to obtain more reactive carboxylic groups on their surface and then higher functionality. Secondly the oxidized nanotubes (MWCNT-COOH) were dispersed in tetrahydrofuran (THF) and made react...
