ZINC SULFIDE NANOPARTICLE COMPOSITION, ANTIBACTERIAL AND ANTI-FUNGICIDAL POLYMER RESIN MASTER BATCH CONTAINING SAME, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a composition containing zinc sulfide nanoparticles having an average diameter of 20 nm or less and having a thiol protective surface, an antibacterial and anti-fungicidal polymer resin master batch containing the same. Particularly, the zinc sulfide nanoparticles having a thiol protective surface are easily distributed in a polymer resin matrix and enable uniform distribution without aggregation. In addition, the zinc sulfide nanoparticles having a thiol protective surface can endure the formation temperature of a thermoplastic polymer resin matrix.
