| 英文摘要 | The polyamide 12 (PA12) with different crystal forms is prepared with three crystallization paths. The crystal structures and corresponding thermal properties are systematically investigated. The results reveal that an alpha-form and a mixed (alpha + gamma)-form of PA12 can be obtained by casting at 30 degrees C and (40-80 degrees C), respectively. Meanwhile, the gamma-form of PA12 can be obtained by both casting at 90 degrees C and slow melt cooling. However, the gamma'-form is obtained only by melt quenching. Both the gamma and gamma' forms of PA12 exhibit a single melting peak, whereas the alpha-form exhibits two melting peaks. The higher peak is attributed to the melting of gamma-PA12, which originates from the melting-recrystallization of the alpha-PA12. It is found that the tensile properties of PA12 depend on the crystal forms. Both the gamma and gamma'-PA12 are strong and tough polymer materials, while alpha-PA12 is a strong but brittle polymer material. |
