Nuclear microporous membrane for atomizer plate and making method of nuclear microporous membrane

The invention provides a nuclear microporous membrane for an atomizer plate. The nuclear microporous membrane comprises a microporous area and an immobilized area, wherein the microporous area is arranged in the middle and is provided with conical micropores; and the immobilized area is arranged on the periphery of the microporous area. The nuclear microporous membrane provided by the invention has the beneficial effects that 1) particle size is controlled by pores, so that most drug particles can directly reach pulmonary alveoli, and can act on lung inflammation sites through effects of gravity deposition and dispersion deposition; 2) pore pattern of the nuclear microporous membrane can be optionally adjusted, so that a purpose of conducting passive targeted therapy can be achieved; 3) anatomizing dosage is controlled by the density of pores of the nuclear microporous membrane; therefore, drug dosage can be adjusted, and it is possible to conduct large-dose administration within a short time; 4) ultra-high f
