This invention discloses a method for preparing an antibacterial composite material with flame-retardant properties and its application. It introduces a multifunctional molybdate material into different polymer matrix systems to construct a functional composite material with both antibacterial and flame-retardant properties. The molybdate, as a functional reinforcing phase, is uniformly dispersed in the composite material.
