AB  - Nano silica (SiO(2)) is usually used as a common reinforcing agent in polymer 
      materials, in which the interfacial interaction greatly affects the mechanical 
      properties of the composites. The reinforcement effect of silica on non-polar 
      polymer is restricted due to their poor compatibility. In this work, amphipathic 
      lignin modified by quaternization and alkylation was used as a modifier for 
      silica to prepare hydrophobic lignin/SiO(2) nanoparticles by in-situ one-pot 
      co-precipitation method. In alkaline solution, hydrophobic lignin and SiO(2) 
      (from Na(2)SiO(3)) were self-assembled to form nanospheres through electrostatic 
      and hydrophobic interactions. The results showed that the lignin/SiO(2) 
      nanoparticles were highly hydrophobic nanospheres with macropores in the surface. 
      When the lignin/SiO(2) nanoparticles (10 wt%) were added to reinforce 
      high-density polyethylene (HDPE), the mechanical properties of HDPE were improved 
      with the strength of 24.5 MPa and the elongation of 1096%, which were increased 
      by 10.4% and 14.3% compared with the control HDPE, because of the good 
      compatibility and large bonding area. This work puts forward a new solution for 
      the application of lignin in reinforcement of non-polar polymers.
