摘要: Poly(trimethylene terephthalate) (PTT) with its unique spherulitic morphologies, highly birefringent features, and crystal stability serves as a good candidate to study polymer crystallization assembly. This review compiles the main findings on in PTT, including birefringence morphology, thermal behavior, well interior structure of PTT banded spherulites, order elucidate origin formation mechanism spherulites. Interior observation through inner anatomy assembly spherulites hidden under top surface is necessary provide complete picture for unsettled arguments about mechanism. Careful attention should be taken when selecting etching agent exposing lamellar spherulite, otherwise, misinterpretation could result
