TI  - Influence of Quaternary Ammonium Salt Functionalized Chitosan Additive as 
      Sustainable Filler for High-Density Polyethylene Composites.

AB  - In this study, an antimicrobial packaging material was successfully developed 
      with blends of high-density polyethylene (HDPE) and chitosan (CS) made by melt 
      processing. In the different HDPE/CS composites, the CS content effect (up to 
      40%), and the addition of quaternary ammonium salt functionalized chitosan 
      (CS-CTAB) as an additive were evaluated by X-ray diffraction (XRD), differential 
      scanning calorimetry (DSC), thermogravimetric analyses (TG), tensile strength, 
      scanning electron microscopy (SEM) and antimicrobial activity. When analyzing the 
      effect of the additive in the different HDPE/CS composites, it was observed that 
      the compositions with 10 and 20 %wt of chitosan showed better elongation values 
      (~13% and 10%) as well as a higher decomposition temperature at 20% mass loss 
      (T20) varying from (321-332  degrees C and 302-312  degrees C), respectively, in relation to the 
      other compositions, regardless of the type of additive used, it acted as an 
      antimicrobial agent, promoting inhibition of microbial growth against the strains 
      gram-positive and gram-negative used in this work, making the different HDPE/CS 
      composites suitable candidates for use in food packaging.
