| 摘 要： | 采用变温FTIR光谱法研究了原料PET和PET/nano-CaCO3(MPET)复合材料体系在40~250℃之间逐渐升温过程中,PET基体的固态转变。通过研究PET内标谱带1 410 cm-1与结晶相关谱带1 342cm-1吸光度之比值随温度变化关系曲线,结合其在同样条件下的差热扫描(DSC)曲线,分析了纳米CaCO3粒子的加入对PET固态转变和结晶相关谱带的影响,表明纳米CaCO3粒子的加入显著改善了PET的结晶和熔融行为。 |
| 关 键 词： | 变温FTIR光谱 PET/nano-CaCO3复合材料 固态转变 |

| Abstract: | Solid state transformation of crude poly(ethylene terephthalate)(PET)and PET/nano-CaCO_3(MPET)composites were studied by variable temperature FTIR spectroscopy during the heating process from 40 to 250 ℃.The effects of nanometer calcium carbonate(nano-CaCO_3)on the solid state transformation and crystal correlation bands of MPET composites were analyzed by the curves of the ratio of 1 342 and 1 410 cm~(-1) absorbency(A_(1342)/A_(1410))with temperature increasing,and together with DSC curves in the same condition.The results showed that the crystallization degrees of crude PET and MPET are obviously different in this condition by adding nano-CaCO_3 particles as inhomogeneous nucleating agents. |
