杯芳烃氰酸酯的热固化对其纳米孔结构的影响

Effect of thermal curing of calixarene cyanate ester on its nanopore structure

合成了对叔丁基杯【4】芳烃氰酸酯树脂，通过傅里叶红外光谱，核磁共振氢谱，示差扫描量热分析，热失重及小角x射线衍射分析研究了固化条件，对位取代基大小对叔丁基杯[4]芳烃氰酸酯纳米孔结构的影响。结果表明，为使对叔丁基杯芳烃氰酸酯固化后仍保留规则的纳米孔结构，应采用较低的固化温度。当杯芳烃对位取代基较大时，固化温度可较高。该纳米孔杯芳烃氰酸酯树脂有望用作轻质高强耐热复合材料基体。

The p-tert-butylcalix[4]arene cyanate resin was synthesized. The effects of curing conditions and group sizes of para substituents on the nanopore structures of p-tert-butylcalix [4] arene cyanate resins were investigated by Fourier transform infrared spectroscopy, 1-HNMR spectroscopy, differential scanning calorimetry, thermogravimetry and small-angle X-ray diffraction analysis. The results showed that the p-tert-butyl calixarene cyanate should be cured at lower temperature in order to maintain the regular nanopore structure after curing. When the calixarene para-substituent was larger, the curing temperature could be higher. The nanoporous calixarene cyanate resin was expected to be used as a lightweight high-strength and heat-resistant composite matrix.
