Polymers nano materials refer to polymers of at least one-dimensional size up to 100 nm. Polymers nano materials have great potential for intelligence, adaptability and repairability fields, enabling precise control of structures from molecules to macro-solids. In addition, some polymers nano materials with special structures such as block copolymers, hyperbranched polymers and dendrimers can form various ordered structures through self-assembly or layer-by-layer assembly, which have broad application prospects in the field of microelectronics. Therefore, with the advantages of unique characteristics and excellent properties, polymers nano materials have attracted more and more attentions.
