Template-free method synthesized NaxCa2.38-xAl2Si57.2O118.59 zeolite particles for enhanced stability

Abstract

Zeolites have been shown to accelerate hemostasis, improve trauma healing, and provide the resulting multifunctional hemostatic materials, due to their distinctive microporous structure and interfacial properties. However, natural zeolites general contain impurities and it is difficult to produce hemostatic powder of appropriate size using direct crushing methods. Herein, we develop a template free one-step hydrothermal process to synthesized NaxCa2.38−xAl2Si57.2O118.59 zeolite particles with controllable size. The size of NaxCa2.38−xAl2Si57.2O118.59 zeolite particles can be controlled from 1 to 10 µm. The ordered pores in the synthesized NaxCa2.38−xAl2Si57.2O118.59 zeolites exhibit a typical two-dimensional hexagonal structure. The synthesized zeolites exhibit excellent stability in both natural environments and serum. The Na2.38Al2Si57.2O118.59 zeolite particles maintain high stability of morphology and structure after water flow treatment. Those stability results ensure the preservation and use possibility of zeolite hemostatic powder in special environments, such as battlefield, underwater, and extreme weather.
