3,4-二羟苯基丙酸

3,4-Dihydroxyhydrocinnamic acid (DHCA) belongs to the class of monomers known as hydroxycinnamic acids. DHCA, also known as hydrocaffeic acid, can be polymerized to form various caffeic acid-based polymers. These polymers can be used in the development of coatings, films, and packaging materials due to their antioxidant and antimicrobial properties. caffeic acid-based polymers have also shown potential applications in drug delivery systems, tissue engineering, and encapsulation of bioactive compounds. Additionally, these polymers can be incorporated into cosmetic and personal care products due to their antioxidant and anti-inflammatory properties.

3,4-二羟基羟基肉桂酸（DHCA）可作为单体 以制备仿生肌肉生物黏附聚合物。聚合物的强粘附作用 是由于存在于聚合物末端链和底物表面的 儿茶酚基团的相互作用。

它也可用于纳米颗粒的表面功能化。DHCA 的功能化不仅提高了纳米颗粒的水溶性，且由于表面羧基的存在，为进一步改性提供了平台。
