Abstract
A hemostatic compound is provided. The hemostatic compound comprises molecular sieves and a fiber. The molecular sieves are independently dispersed on a fiber surface of the fiber without agglomeration and directly contact the fiber surface. A first surface of the molecular sieve contacted with the fiber is defined as an inner surface, and a second surface of the molecular sieve uncontacted with the fiber is defined as an outer surface. The molecular sieve forms a growth-matched coupling with the fiber on the inner surface, and the growth-matched coupling refers to that a plurality of molecular sieve microparticles grow to match the fiber surface to form a tightly-coupled coupling interface that matches the fiber surface.
