The present research work investigates the effect of modified halloysite nanotubes (mHNTs) on the mechanical, thermal, and morphological properties of polyether ether ketone (PEEK) and polyetherimide (PEI). The developed PEEK/PEI blend matrix with 1 wt% of mHNTs shows a significant enhancement in mechanical properties like tensile, flexural, hardness, and impact. The developed blend matrix of PEEK/PEI matrix with mHNTs shows a significant enhancement of 25% in storage modulus (E′) and 13°C in glass transition temperature (Tg). In addition, an appreciable improvement of 26°C observed in maximum degradation temperature (Tmax). The effectiveness of the dispersion of mHNTs in the PEEK/PEI blend matrix was investigated by using SEM and TEM micrographs. The micrographs revealed that the mHNTs are uniformly dispersed in the PEEK/PEI matrix. The possible interaction of HNTs with PEEK/PEI and mHNTs with PEEK/PEI matrix were analyzed by Fourier Transform Infrared Spectroscopy (FTIR).

表面改性埃洛石纳米管增强的 PEEK/PEI 共混基体的机械和热性能

目前的研究工作研究了改性埃洛石纳米管 (mHNT) 对聚醚醚酮 (PEEK) 和聚醚酰亚胺 (PEI) 的机械、热和形态特性的影响。开发的 PEEK/PEI 共混基质与 1 wt% 的 mHNTs 显示出拉伸、弯曲、硬度和冲击等机械性能的显着增强。开发的 PEEK/PEI 基体与 mHNT 的共混基体的储能模量 (E') 显着提高了 25%,玻璃化转变温度 (Tg) 显着提高了 13°C。此外,在最大降解温度 (T max)。通过使用 SEM 和 TEM 显微照片研究了 mHNT 在 PEEK/PEI 共混基质中的分散效果。显微照片显示 mHNT 均匀分散在 PEEK/PEI 基质中。通过傅里叶变换红外光谱 (FTIR) 分析了 HNT 与 PEEK/PEI 和 mHNT 与 PEEK/PEI 基质之间可能的相互作用。
