When temperature become higher, the movement of gas molecule will be acuter, diffusion coefficient will be higher. Permeability coefficient has a direct ratio with film transmission rate . Continue reading
When temperature rises, the diffusion rate of permeance molecule in the polymer is accelerated; the energy of gas molecule is increased, so the permeability of the materials will be increased. Continue reading
