As an irreplaceable material, polymer has been widely used in all aspects of our life. With the joint efforts of researchers, significant achievements have been accomplished in supramolecular polymer, graphene, high-performance materials and nanomultifunctional materials of polymer science. This paper makes a brief introduction to several outstanding results accomplished in 2017, including stretchable polymer semiconductor, flexible energy storage materials, efficient and accurate preparation of asymmetric polymer brushes, carbon dioxide adsorption, plastic recycling and reuse,and application of polymers in drug detection. Among them the research in extensible polymer,in particular, has made great breakthroughs in the year and seems soon applicable to use in wearable electronic equipment.
