Study on a novel dosimeter based on polyethylene–carbon nanotube composite

摘要: Abstract In this research work, the electric current of polyethylene-carbon nanotube composite, in electrical percolation threshold region, over absorbed dose under applied bias voltage was investigated via finite element method. The geometry formed by a two-dimensional cross-sectional view randomly orientated nanotubes as ellipses. variable range hopping model developed Mott and thermally activated used to calculate conductivity carbon polymer, respectively. Regarding calorimetric approach, we considered equal heat capacity composite multiplied temperature rise. Results showed that kind can be for low rate applications monitoring radiation protection utilizations.
