Hydrophilic polymer refers to organic polymers rich in polar groups, including natural polymers such as starch, protein, cellulose, and the synthesis of polyacrylic acid, polypropylene phthalimide, polyvinyl alcohol, polyurethane, polyphthalamine polymer. After more than half a century of development, hydrophilic polymers have become a relatively mature research field. Hydrophilic polymers have good biocompatibility and are widely used in agricultural, forestry, sanitary products, medical care, modified thickening and other conventional applications. Due to the diversity and intelligence of hydrophilic polymers, in recent years, researchers have conducted exploratory experiments in emerging industries such as tissue engineering, biological materials, drug release, and optoelectronic information materials, and have obtained a large number of research results, which have huge potential application value.
