“…The magnitude of k signifies the structural characteristics of the polymer and provides an idea about the nature of the interaction between the polymer and the solvent. 25 The values of k in the particle filled systems are lower than the unfilled systems. This indicates that the presence of filler can reduce the interaction between the polymer and the solvent.…”

The solvent transport properties of the prepared composites were analysed using solvents of varying cohesive energy density and the effect of both modified as well as unmodified filler on the sorption and diffusion behaviour of NR vulcanisates has been investigated. It is found that the equilibrium uptake decreases with increase in filler content, as anticipated owing to the restrictions offered by the filler for solvents to diffuse into the polymer matrix. The mechanism of transport in natural rubber composites was carefully tracked and it was found to exhibit an anomalous mode of solvent transport where the polymer relaxation is in par with the rate of diffusion. Theoretical modelling of the swelling parameters was done and the results were found to be in agreement with existing models. The excellent swelling resistance coupled with the simultaneous improvement in mechanical properties would definitely pave way for the utilisation of these composites as barrier membranes.

“…This trend is consistent with experimental observations on similar composites. [43][44][45] Moreover, this trend is expected to be more pronounced when the swollen samples are subjected to uniaxial deformation due the volume expansion that can be caused by the separation between the polymer and the filler creating vacuoles. 46 For these reasons, in our experiment the maximal deformation is limited to 40%.…”

We consider the hyperelastic response of semi‐crystalline ethylene–co‐butyl acrylate (EBA) samples filled with carbon black (CB) particles. Such material is structurally complex with its microstructure being characterized by many structural parameters including crosslink density, filler/matrix interfaces, crystallinity, filler network, and chain entanglement which have different degrees of influence on the effective mechanical properties. We evaluate the ability of a number of analytical models to correctly reproduce the non‐linear elastic mechanical response of these samples. We do this by considering either dry samples, or samples which are swollen by a non‐polar solvent (toluene) at equilibrium, and subjected to uniaxial tension at room temperature. As test cases, we focus on six physical models for the purpose of analyzing the stress–strain curves of samples with different cross‐linking densities. Among these frameworks, we show that the Mooney–Rivlin (MR), Ogden, and eight‐chain models accurately describe the stress–strain curves of both dry and swollen CB‐EBA samples. These findings highlight the possibility of attaining a diverse set of mechanical properties of filled polymer samples by tailoring their structural parameters.

Influence of POSS fillers on the transport properties of natural rubber nanocomposites

Three types of polyhedral oligomeric silsesquioxane (POSS)—octaphenyl (OP), POSS@TESPT (TT), and MWCNT@POSS (VC)—were incorporated into natural rubber (NR) to fabricate nanocomposites. The transport properties of POSS–NR nanocomposites were studied through solvent diffusion techniques. Diffusion studies were done with toluene (aromatic solvent) and the influence of nanofiller structure, concentration and compatibility with the NR matrix on various diffusion parameters were analyzed. The fillers that have good interaction with the polymer matrix showed the lowest solvent uptake. The network structure analysis revealed that the polymer chains deformed affinely. The effect of fillers on the chain flexibility was also discussed based on mechanical property studies. POLYM. COMPOS., 40:3020–3031, 2019. © 2018 Society of Plastics Engineers
