Abstract

The wide range applications of carbon nanomaterials in many aspects of life gave a push to researchers around the world to work hard and continuously to develop these nanomaterials and their fabrication techniques [2]. The properties of nanomaterials which are in the range from 1-100 nm of size, are quietly different from that of bulk- materials .The investigations of nano-materials under high pressure can add useful information and best understanding of these materials since they are infinitesimally small in size so high pressure's affect will be significant on their properties.One of the methods used to introduce modifications to the configuration and structure of nano-particles is by applying high pressure on these particles. The variation of V/Vo for nano C60, C70, C84, and CNT against high pressure has been evaluated using Vinet and Birch-Marnghan EOSs as well as Nano EOSs. Different equations' outputs were compared to experimental data as well as to each other. The compatibility of the various EOS results suggests that the EOSs of bulk materials may be applied to the computations of nanoparticles. Calculations of bulk modulus fluctuations under high pressure for C60, C70, C84, and CNT Materials showed a viable use for bulk EOSs. and nano materials except Birch-Marnghan EOS.
