AB  - The flammability of synthetic thermoplastic polymers has been recognized as an 
      increasingly important safety problem. The goal of this study was to evaluate a 
      green and safe fire-retardant system comprising of cellulose nanocrystals (CNC) 
      and zinc oxide nanoparticles (ZnO). CNCs coated with nano ZnO were incorporated 
      in the high-density polyethylene polymer (HDPE) matrix at different 
      concentrations. Fire testing results of different formulations of HDPE containing 
      0.4 to 1.0% zinc oxide coated CNC exhibited a substantial decrease in the average 
      mass loss, peak heat release rate and total smoke release. The time to ignition 
      exhibited a positive correlation with CNC-ZnO concentration. Modest improvement 
      in the flexural strength and moduli of composites was noticed validating no 
      adverse effects of CNC-ZnO complex. The transmission electron microscopy further 
      confirmed dispersion of nanoparticles as well as the presence of some 
      nanoparticle aggregates in the matrix. The uniform dispersion of CNC-ZnO complex 
      is expected to further improve fire and mechanical properties of polymer.
