This work reports on the outcome of the calcination of gold nanoparticles incorporated polyacrylonitrile nanofibers in air which results in the formation of gold spherical and flake cluster assemblies. The architecture and morphology of gold nanostructures play a role in determining their different applications. The results of this research showed that calcination at 650 °C for 5 h led to almost complete disintegration and disappearance of the poly(acrylonitrile) matrix and polyhedral nanostructures were formed. FTIR analysis showed the complete disappearance of poly(acrylonitrile) matrix at calcination temperatures of 850 °C and 1000 °C. XRD analysis also showed the complete disappearance of poly(acrylonitrile) at calcination temperatures above 850 °C. SEM micrographs taken after calcination of the precursor showed that calcination around 850 °C leads to the formation of spherical gold clusters, whereas, calcination at 1000 °C produces gold flake clusters.

这项工作报道了掺入聚丙烯腈纳米纤维的金纳米颗粒在空气中的煅烧结果，这导致了金球形和片状簇组件的形成。金纳米结构的结构和形态在确定它们的不同应用方面起着作用。研究结果表明，在650°C下煅烧5 h导致聚丙烯腈基体几乎完全崩解和消失，形成了多面体纳米结构。FTIR分析表明，在850°C和1000°C的煅烧温度下，聚丙烯腈基质完全消失。XRD分析还显示，在高于850℃的煅烧温度下，聚丙烯腈完全消失。
