Poly(bisphenol-A carbonate) (PC) is a widely used amorphous polymer in daily life with various applications. It was known that PC could be easily crystalized by some solution methods such as precipitation, resulted to porous particles with 3-dimensional orthorhombic structure. Previously, the concept of hypo-crystal polymer crystallization was reported, providing unique 1-dimensional crystal structure of polymer with the chain stretched up to 60% of contour length. In this research, similar process was applied for PC crystallization, resulted to long fibers of PC which were oriented differently depending on PC film thickness. Also, crystallization signals in DSC, FT-IR and X-ray scattering were different from conventional PC 3-dimensional crystal structure. |
