Özet:

 

High density polyethylene (HDPE) was compounded with   thermally exfoliated graphene oxide (TEGO) by thermokinetic mixing in a   short time. High shear rates during the compounding process provided high   exfoliation and proper dispersion of graphene layers in the polymer matrix.   Different TEGO/polymer ratios were used to get efficient melt mixing.   Structural analysis by spectroscopic techniques confirmed the exfoliation of   TEGO sheets and the coverage of their surfaces by HDPE chains. Furthermore,   homogeneous dispersion of graphene sheets in the matrix led to the   enhancement in the mechanical and thermal properties of HPDE-based   nanocomposites. Especially stress concentration sites were significantly   reduced by preventing the agglomeration and restacking of graphene sheets in   the matrix. Therefore, the tensile modulus and strength of HDPE   nanocomposite increased about 36.5% and 45.7%, respectively, with the   incorporation of 2 wt% TEGO. Microscopy analysis showed the separation of   graphene layers in the cross-sectional area of composite specimens.   TEGO-reinforced HDPE nanocomposites showed high thermal stability compared   to the neat sample.
