Abstract
A novel and simple synthetic method for the preparation of aragonite whiske rs has been developed, whereby aqueous solutions of CaCl2 and Na2CO3 are co mbined in the presence of a suitable surfactant, poly(ethylene glycol)-20 0 00 (abbreviated as PEG), under ambient reaction conditions. The whiskers ha ve high aspect ratios ranging from 20 to 80 with diameters in the range 0.5 0-1 mum. They were characterized by powder X-ray diffraction (XRD), transmi ssion electron microscopy (TEM), Fourier transform infrared spectroscopy (F TIR) and Raman spectroscopy. The formation of aragonite whiskers is due to the soft template effect of PEG.
