含氟聚酰亚胺1,3-BPA-6FDA-DR1的合成及其热光性能
摘要:
用1,3-双(3-氨基苯氧基)苯(1,3-BPA)、4,4'-(六氟异丙基)-苯二酸酐(6FDA)和分散红1(DR1)合成了含氟聚酰亚胺,采用示差扫描量热(DSC)、热失重分析(TGA)和紫外、红外吸收光谱等测试技术对该聚酰亚胺的热稳定性和结构进行了表征。结果显示,该聚酰亚胺的玻璃化转变温度(Tg)和在5%的质量损失温度分别为238和287℃,表明具有较好的热稳定性。不同浓度的材料在自然光下的热光系数(dn/dT)值为(-2.31~-3.04)×10-4/℃,体积热膨胀系数变化率(dβ/dT)为(2.56~4.32)×10-7/℃;一定浓度的材料在436 nm单波长光照射下的热光系数(dn/dT)值为-3.08×10-4/℃,体热膨胀系数变化率(dβ/dT)为4.72×10-7/℃,表明该聚合物在低驱动功率的新型数字热光开关、光通信器件等领域具有潜在的应用前景。

Synthesis and Thermal-Optical Properties of Fluorine-containing Polyimide 1,3-BPA-6FDA-DR1
Abstract:
A fluorine-containing polyimide was synthesized from 1,3-bis(4-aminophenoxy)benzene (1,3-BPA), 4,4'-(hexafluoroisopropylidene)diphthalic anhydride(6FDA) and dispersed red 1(DR1). The thermal properties and structure of the polymer were characterized by differential scanning calorimetry(DSC), thermal gravimetric analysis(TGA), UV-Vis and FT-IR. The glass transition temperature(Tg) and the temperature at which 5% mass loss of polyimide occurred were 238 and 287℃, respectively. The material has good thermal stability. The dn/dT and dβ/dT were -2.31×10-4~-3.04×10-4 and 2.56×10-7~4.32×10-7(different concentration, natural light), -3.08×10-4 and 4.72×10-7(436 nm)/℃, respectively. The compound may be used in new digital optical switches with low driving power and optical communication devices.
