主　　题：Nanochannel Unidirectional rectification Composited membrane Ion transport Rectification mapping 

摘      要：Controlling ions transport across the membrane at different pH environments is essential for the physiological process and artificial *** efforts have been devoted to pH-responsive ion gating,while rarely systems can maintain the rectification in pH-changing ***,a composite nanochannel system is fabricated,which shows unidirectional rectification with high performance in a wide pH *** the system,block copolymer(BCP) and polyethylene te rephthalate(PET) are employed for the amphoteric nanochannels *** on the composite system,a model is built for the theoretical ***,rectification mapping is conducted on the system,which can provide abundant info rmation about the relations between charge distribution and ions transport prope *** proposed rectification mapping can definitely help to design new materials with special ion transport properties,such as high-performance membranes used in the salinity gradient power generation field.
