Research Progresses of Microporous Polymers as Hydrogen Storage Materials

Microporous polymers which have high surface areas can be as one of physisorption hydrogen storage materials.The hydrogen storage of microporous polymers such as polymer of intrinsic microporosity(PIMs) and hypercrosslinked polymers(HCPs),which compared with others microporous materials such as carbon,metal-organic frameworks(MOFs) under the condition of 0.1MPa and 77K are reviewed.And effect of factors(surface area,porous size and porous size distribution,binding affinities with H_2) on the hydrogen storage of microporous polymers are discussed.Among these polymers,HCPs is becoming one of the most potential hydrogen storage materials of microporous polymers,as there are more monomers to choose and their porous morphology are easy to control.
