    摘要: A high pressure gas hose and related methods of transporting high pressure gases in which gas permeability throughout a length of the high pressure gas hose is reduced. The high pressure gas hose can have an outer tube and the inner tube. The outer tube can be formed of a resistant polymer material such as PTFE. The inner tube can include a matrix formed of PTFE and graphene nano-platelets or nano-particles. The graphene nano-platelets define a tortuous path within the matrix such that gas permeability is reduced through an inner tube wall thickness. Gas permeability throughout a length of the high pressure gas hose can be less that about 20 ml/m/hr. The high pressure gas hose can find practical application in natural gas applications, automotive applications, cooling and refrigeration applications and other applications in which it is desired to have low gas permeability in high pressure applications.
