Beschreibung
Zusammenfassung:	The invention discloses a preparation method of an isolated thermoplastic elastomer composite microporous electromagnetic shielding material. The preparation method specifically comprises the following steps: 1, adding MAX-phase ceramic powder into a hydrochloric acid/lithium fluoride mixed solution to obtain a dark green aqueous dispersion; 2, placing the thermoplastic elastomer beads in an autoclave for saturated absorption, then carrying out microcellular foaming on the completely saturated thermoplastic elastomer beads in a high-temperature foaming device to obtain thermoplastic elastomermicrocellular foamed beads with different foaming ratios; 3, immersing the thermoplastic elastomer microcellular foamed beads into the aqueous dispersion to obtain wrapped thermoplastic elastomer composite microcellular beads; and 4, putting the wrapped thermoplastic elastomer composite microporous beads into a mold, and pouring formic acid to dissolve the surfaces of the composite microporous beads, thereby obtaining the
