Production Optimization Of Ring-Banded Spherulitic Crystals Of Poly (3-Butylthiophene-2,5-Diyl) Using Controlled Solution Evaporation, Frederick Paul Henderson Iii
Conductive polymers can carry a charge due to the presence of excess electrons along the carbon backbone. By growing these polymers into crystals, the usual insulative isotropic matrix that polymers form will be replaced with anisotropic regions where conduction is possible parallel to the crystal lattice growth direction. In previous research, while growing sphere shaped crystals it was observed that a few would exhibit rings that formed parallel to the circumference of the sphere. In this project, the conditions to produce this ring structure were examined by looking at two polymer solutions (with carbon disulfide or dichlorobenzene as solvent) and ...
