Abstract

Abstract: A simple one-pot double in-situ synthetic method was proposed to fabricate transparent semi-aromatic polyamides (SAPA) nanocomposites with upconversion nanoparticles (UCNP) as nanophase contents by combining hydrothermal method with melt polycondensation method. The key to this method is that the nanoparticles and polyamides were prepared in one-pot by simply mixing polyamides monomers and UCNP precursors as the raw materials without preparing polyamides or nanoparticles in advance. This approach enables the simple fabrication of transparent upconversion luminescent semi-aromatic polyamides nanocomposites with UCNP uniformly dispersed and can be extend to other kinds of polyamides and functional nanoparticles to prepare various polyamide nanocomposites. Highlights: One-pot double in-situ fabrication of SAPA/UCNP@SAPA nanocomposites. Polyamide monomers and UCNP precursors mixtures as the raw materials in autoclave. Formation of nanoparticles in the first hydrothermal process. Formation of polyamides nanocomposites in the second polycondensation process. Nanoparticles uniformly dispersed in the polyamide nanocomposites with function.
