Abstract: A large-scale fabrication technique for PIM-1 asymmetric membranes doped with low-molecular-weight polyethylene glycol for gas separation. Based on the membrane fabrication technique of dry/wet phase inversion, firstly, the coagulation process of casting solution is regulated by low-molecular-weight polyethylene glycol to thin the dense functional layer, to improve the hydrophilicity of the membrane structure, and to form mass transfer channels for the diffusion of polyethylene glycol into the dense functional layer. Then, directional migration and enrichment of polyethylene glycol are realized through capillary action induced by directional water evaporation for large-scale fabrication of PIM-1 asymmetric membranes doped with low-molecular-weight polyethylene glycol in the dense functional layer for gas separation, and thereafter high permeation ability and high selectivity are achieved simultaneously.

Abstract: Embodiments of this application disclose a communication method and a communication apparatus, to establish two intra-frequency co-coverage cells within a same frequency band, and arrange time-frequency resources respectively used by the two cells in a time division or frequency division manner to avoid co-channel interference, so that the two cells back up each other. When one cell of the cells is abnormal, the other cell can still provide a service for a terminal device. Because the two cells share the frequency band, spectrum resources can be reduced, and consumption of the time-frequency resources can be reduced. In addition, radio resource utilization can be improved while a reliability gain of dual-network system-level backup is obtained.

In the invention, firstly, polybenzimidazole is grafted with the non-cationic side chains to the max grafting rate to synthesize the de-protonated comb-shaped polybenzimidazole material, avoiding the N—H in benzimidazole forms ionic binding with cationic functional groups, which will reduce the reactivity and mobility of cationic groups; then react de-protonated comb-shaped polybenzimidazole with quaternization reagent to attach the pendent side chain with cationic functional groups, making it easy to aggregate to form ion clusters and hydrophilic/hydrophobic microphase separation. The anion exchange membrane prepared in this invention has excellent conductivity, mechanical properties and alkaline stability.
