Analysis of the Connecting Effectiveness of the Interphase Zone on the Tensile Properties of Carbon Nanotubes (CNT) Reinforced Nanocomposite

Abstract

The establishment of interphase region around nanoparticles accelerates the percolating of carbon nanotubes (CNT) in polymer nanocomposites reinforced with CNT (PCNT), due to the linking productivity of interphase district before the physical connecting of nanoparticles. Therefore, the interphase is an important character in the networks of CNT in PCNT. Here, a simulation study is presented to investigate the interphase connection in the mechanical possessions of PCNT including tensile modulus and strength. A number of models comprising Takayanagi, Ouali, Pukanszky and Callister are developed by the assumption of an interphase district in the CNT excluded volume. The advanced models depict the optimistic influences of reedy and lengthy CNT besides dense interphase on the stiffness and tensile power of nanocomposites. The Pukanszky calculations depict that the interphase strength plays a more noteworthy role in the nanocomposites strength compared to the CNT length.

Enhanced Functional Properties of Low-Density Polyethylene Nanocomposites Containing Hybrid Fillers of Multi-Walled Carbon Nanotubes and Nano Carbon Black

“…The SEM analysis ( Figure 2 and Figure 3 ) indicated that both of the used carbon nanofillers are rather homogeneously dispersed in the LDPE matrix but also at higher concentrations the agglomerates of MWCNT S and nCB are incidentally present. Experimental and theoretical studies of the mechanical and electrical percolation in CNTs/polymer nanocomposites have shown that their tensile strength weakens at high filler loading, due to the aggregation of nanofillers and stress concentration, while the tensile modulus and electrical conductivity improve upon increasing of CNTs loading [ 26 , 27 , 28 ]. The investigated here LDPE nanocomposites shows such behaviour.…”

“…Whereas the tensile modulus and electrical conductivity (see Figure 4 ) increase with the hybrid CNTs/nCB system or nCB loading. Besides, if in the nanocomposite, the high interfacial area and the strong interfacial interaction between nanofillers and polymer matrix occur, the third phase as interphase is formed [ 28 , 29 ]. This interphase significantly affects the mechanical properties of polymer nanocomposites.…”

“…The interphase regions are commonly formed in nanocomposites, due to the large interfacial zone amongst polymer medium and nanofiller [ 34 , 35 , 36 , 37 , 38 , 39 ]. The characters of interphase dimensions and toughness in the rigidity of nanocomposites have been conferred in previous articles [ 40 , 41 , 42 , 43 , 44 , 45 , 46 ].…”

Development of Trans-1,4-Polyisoprene Shape-Memory Polymer Composites Reinforced with Carbon Nanotubes Modified by Polydopamine

“…Carbon nanotubes (CNTs) are a new type of one-dimensional nanomaterial where the carbon atoms in the tube walls form a hexagonal network structure due to sp 2 hybridization; the basic network is the same as that of graphene. The C=C covalent bond formed by sp 2 hybridization is one of the strongest covalent bonds in nature, so carbon nanotubes have extremely high mechanical properties [ 14 , 15 ]. The elastic modulus of CNTs can reach 1TPa, which is almost the same as that of diamond and about five times that of steel [ 16 ].…”
