Sapkota, Janak Garcia, Julio Cesar Martinez Lattuada, Marco 2017-09-15 The mechanical reinforcement of nanocomposites containing nanorods-like fillers such as cellulose nanocrystals (CNCs) isoften interpreted by adapting the classical parallel–series model, assuming a simple hyperbolic dependence between the percolationthreshold and aspect ratio. However, such assumptions are valid only for nanorods with high aspect ratio and often are misinterpretingthe reinforcement obtained at low volume fraction of filler loading. To elucidate this intriguing scenario, we proposed a newapproach and validated it by compiling and reinterpreting some of available literature that represent the experimental reinforcementwith CNCs. Our approach showed better accuracy, specifically for the cases of CNC nanorods with lower aspect ratio. We concludethat this route permits a more realistic evaluation of the mechanical reinforcement, where a physical parameter accounting the polymerfiller association is introduced. application/pdf https://folia.unifr.ch/global/documents/306086 https://folia.unifr.ch/documents/306086/files/lat_rmr.pdf https://folia.unifr.ch/documents/306086/files/lat_rmr_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1002/app.45254 info:eu-repo/semantics/openAccess License undefined Journal of Applied Polymer Science. - 2017, vol. 134, no. 35, p. 45254 info:eu-repo/classification/udc/54 Reinterpretation of the mechanical reinforcement of polymer nanocomposites reinforced with cellulose nanorods http://purl.org/coar/resource_type/c_6501
