摘要

Nanotube-shaped precursor which is composed of layered structured sodium dodecylsulfate (SDS) calcium carbonate were obtained by titration of an aqueous solution of Na(2)CO(3) into an aqueous solution containing CaCl(2) and SDS at 333-335 K. A unit of the repetition of the precursor was about 4 nm. Nanotube-shaped composite which is composed of CaCO(3) and CaSO(4) of 100-200 nm in diameter and 0.5-2 mu m in length was obtained from nanotube-shaped precursor composed of layers of CaCO(3) and SDS by calcinations at 673 K in air. The precursor sheet composed of CaCO(3) layers on which SDS molecules attached to both side seemed to curl up and form a pipe.
