Time‐dependent properties of high‐density polyethylene with wood/graphene nanoplatelets reinforcement

چکیده
The effect of graphene nanoplatelets (GNPs) on the long-term performance wood fiber/high-density polyethylene (HDPE) composite is investigated by using short-term creep tests with an efficient, faster data analysis approach. Previously, it was shown that addition GNPs at 15 wt% into HDPE reduces viscoplastic (VP) strain developed during 2 h ~50%. current study shows 25 and 40 content in reduce VP strains time >75% no noticeable increased content. However, further results more than 90% total reduction strains. development hybrid composites follows Zapas model. Viscoelastic (VE) response these nonlinear thus described Schapery's Parameters for VE models are obtained from experiments were validated a separate loading-unloading test sequence. Results show very good agreement between predictions studied materials as long micro-damage not present.

Doping Effect of Graphene Nanoplatelets on Electrical Insulation Properties of Polyethylene: From Macroscopic to Molecular Scale
The doping effect of graphene nanoplatelets (GNPs) on electrical insulation properties of polyethylene (PE) was studied by combining experimental and theoretical methods. The electric conduction properties and trap characteristics were tested for pure PE and PE/GNPs composites by using a direct measurement method and a thermal stimulated current (TSC) method. It was found that doping smaller GN...

Colloidal semiconductor quantum wells, also commonly known as nanoplatelets (NPLs), have arisen among the most promising materials for light generation and harvesting applications. Recently, NPLs have been found to assemble in stacks. However, their emerging characteristics essential to these applications have not been previously controlled or understood. In this report, we systematically inves...

Graphene nanoplatelet (xGnP) was investigated as a novel reinforcement filler in mechanical properties for poly(lactic acid) (PLA)/epoxidized palm oil (EPO) blend. PLA/EPO/xGnP green nanocomposites were successfully prepared by melt blending method. PLA/EPO reinforced with xGnP resulted in an increase of up to 26.5% and 60.6% in the tensile strength and elongation at break of the nanocomposites...
