Anisotropy crystal growth

Experimental estimation of growth rate anisotropy. Crystal growth anisotropy is a complex phenomenon which depends on many experimental conditions. However, from a practical point of view it is very important to employ this factor in crystal production techniques since it may help to control the crystal morphology and to explain better the crystal growth phenomena.

Although molecular anisotropy has been noted in several PPy films, the overall degree of crystallinity is very low in these materials. The work by Davidson and coworkers154 on thin PPy films (prepared at very short polymerization times) provides evidence of crystal formation, but the crystal growth is not maintained as the film thickens. Thus, the polymer first formed on the electrode surface may have a high degree of order but does not extend into the bulk structure of thick films.
