    Introduction

    With the development of modern society, some fields need materials with special functions, however, conventional polymers cannot serve the full needs. Therefore, new polymers with special functions are rapidly developing. Such polymers are called functional polymers. Functional polymers are an emerging field developed in the 1960s, and are new materials emerging from the penetration of polymer materials into electronics, biology, energy and other fields. Besides the mechanical properties of conventional polymeric materials, advanced functional polymeric materials could also possess chemical reactivity, photosensitivity, electrical conductivity, catalytic properties, biocompatibility, biological activity, pharmacological properties, selective separation, energy conversion, etc. They have become an important cornerstone in many fields.

    Characteristics

    Functional polymers have high molecular weight, light mass and low density. And they have excellent mechanical properties, insulation properties, and heat insulation properties. Due to the different structures of polymers, their characteristics are also very different. Some specific polymer materials have good optical properties, such as PMMA, PC, PS, some have super high mechanical properties, etc. Functional polymer materials are involved in various aspects of medicine, bioengineering, etc. The raw material sources are also very rich and easy to prepare, and now with the development of science and technology functional polymers are also used in all aspects of life.

    Application

    Functional polymers have potential applications in many fields such as energy harvesting and storage [1], wireless communication industry, biomedicine, oil/water or gas separation [2], smart and bionic industries.

    Adsorptive Polymers

    Adsorptive polymers are materials that utilize the physical or chemical interactions between functional polymer materials and adsorbed substances, including physical attraction, coordination and electrostatic interactions, to temporarily or permanently combine the two and thus exert various functions.

    Photoactive Polymers

    Photoactive polymers also known as photosensitizer, sensitizer and light crosslinking agent which are transfer light energy to some reactants that are not sensitive to visible light in order to improve and expand its photosensitivity.

    Silicone Polymers

    Silicone polymers are organic polymers containing silicon atoms that is an important part of polymer chemistry. The main chain of silicone polymers is composed of Si-O bonds, Si-N bonds or Si-B bonds, while the side chain is composed of silicon atoms connect with other organic groups.
