Graphene shape
WebFigure 1.1: Number of manuscripts with “graphene” in the title posted on the preprint server. In interpreting these numbers, one must, however, consider that several publica-tions on graphene appeared before 2006, e.g. in the framework of carbon-nanotube or graphite research. At this moment, the name “graphene” was not commonly used. WebFeb 28, 2014 · This improved shape recovery by direct heating, but worsened the conductivity of the composite, and consequently the efficiency of resistive heating for shape recovery also declined. Graphene modified with methanol was more effective than pristine graphene in terms of shape recovery by IR heating. Full article
