摘要

Polyamide 12 (PA12)-coated SiO ₂ composite powders were prepared by a dissolution–precipitation method using a mixture of methanol and ethanol as the solvent. The sizes and morphologies of the as-obtained composite powders were determined and observed using a laser particle size analyzer and a scanning electron microscope. The effects of SiO ₂ content on the sizes and the thermal properties of PA12@SiO ₂ composite powders were studied. The results show that the introduction of SiO ₂ decreases the size of the composite powders. With increasing content of SiO ₂ to 9.1 wt%, the d (0.5) of the PA12 powders decreases from 94.2 to 56.2 μm. SiO ₂ promotes the heterogeneous nucleation of PA12, and the size of the composite powders can be tuned by changing the amount of the SiO ₂ . In addition, SiO ₂ particles increase the melting and crystallization temperatures and the crystallization rate of PA12. POLYM. COMPOS., 40:1251–1257, 2019.
