▎ 摘　　要

NOVELTY - Nanohybrid flame retardant composition (C1) comprises: (a) metallic nanoparticles comprising a composition containing a metal e.g. copper, zinc, silver, gold, aluminum, antimony, molybdenum and/or iron; and (b) flame retardant material, where the metallic nanoparticles have a diameter of 1-100 nm and are incorporated onto the flame retardant material having a thickness of 10-10000 nm as a pure metal or metal oxide nanoparticle through a chemical reduction reaction resulting in a nanohybrid flame retardant composition having temperature adaptive flame-retardant behavior. USE - The composition is useful as flame retardant additives for enhanced fire resistance, smoke suppression, and antimicrobial capabilities. ADVANTAGE - The composition has antimicrobial efficacy against Gram-positive and Gram-negative bacteria, fungi, and viruses that is greater than 90%, and synergistic effects of temperature and flame-retardant reactions for enhanced flame retardancy activity and performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) nanohybrid flame retardant composition (C2) comprising (a) and (b) as per se, where the metallic nanoparticles have a diameter of 1-100 nm and are incorporated onto the flame retardant material having a thickness of 10-10000 nm as a pure metal or metal oxide nanoparticle through a high-energy mechanical alloying in the presence of auxiliary additives resulting in a nanohybrid flame retardant composition having temperature adaptive flame-retardant behavior; and (2) preparing flame retardant polymer compositions (C1) and (C2) comprising (a) producing a nanohybrid flame retardant composition, and (b) incorporating and reinforcing polymer or co-polymer matrix with nanohybrid flame retardant compositions, where the nanohybrid flame retardant composition exhibits temperature adaptive flame-retardant behavior.
