An elastic model for bioinspired design of carbon nanotube bundles

摘要: Collagen fibers provide a good example of making strong micro- or mesoscale from nanoscale tropocollagen molecules through staggered and cross-linked organization in bottom-up manner. Mimicking the architectural features collagen has been shown to be promising approach develop carbon nanotube (CNT) high performance. In present work, an elastic model is developed describe load transfer failure propagation within bioinspired CNT bundles, establish relations mechanical properties bundles with number geometrical physical parameters such as aspect ratio longitudinal gap, interface cross-link density, functionalization-induced degradation CNTs, etc. With model, stress distributions along CNT–CNT well every individual are captured, its effects on predicted. The work may useful guidelines for design novel practice. fibril structure this collagen-inspired bundles. established, two modes their transition predicted, optimal eliminate concentration discussed.
