Size control of polydiacetylene microcrystals

Aiming at the preparation of nanometer-size polydiacetylene microcrystals, the crystallization process during reprecipitation method was investigated using electron micrographs and light-scattering technique. We found that an amorphous nanoparticle was formed initially and subsequently crystallized....

Zusammenfassung:Aiming at the preparation of nanometer-size polydiacetylene microcrystals, the crystallization process during reprecipitation method was investigated using electron micrographs and light-scattering technique. We found that an amorphous nanoparticle was formed initially and subsequently crystallized. We conclude that amorphous nanoparticles must be sufficiently small in order to achieve nanometer-size crystals.
