The invention discloses erythrocyte shape colloidal particles and spherical colloid particles assembly and the preparation method and application thereof.The assembly is inlayed by spheroidal particle into the groove of erythrocyte shape particle, and the two closely fits together, and forms assembly；The partial size of the spheroidal particle is 500nm~1300nm；Erythrocyte shape particle, partial size are 1~5 μm, and the shape of groove is hemispherical, and the diameter of groove is 600nm~1500nm；And the partial size of spheroidal particle is the 80%-100% of the groove diameter of erythrocyte shape particle；The present invention successfully realizes the self assembly of the high matching degree of erythrocyte shape particle and spheroidal particle, and assembling effect is significantly promoted, which applies shows excellent photonic crystal rainbow effect in photonic crystal water paint；After regulating and controlling to the dimensional structure of assembly, more gorgeous colors can also be obtained, there will be very big potential using value in water paint. |
