Abstract
A method of preparation of poly(sulphur nitride) whiskers with diameters down to 400 nm and lengths up to 2 mm is described. Through the addition of specific impurities (borneol or camphene) to the highly pure disulphur dinitride starting material, two morphologically different whisker-types were produced. Scanning and transmission electron microscopy revealed fibrous texture in both types of whisker. The fibrils are of irregular shape and are composed of microtwins. A vapour-liquid-solid mechanism is proposed for the growth of disulphur dinitride whiskers. Also the possibility of using a correlated polychromatic percolation as a model for the subsequent polymerization of the whiskers is discussed.
