Description générale
4-Vinylbenzoic acid (4-VBA), also known as styrene-4-carboxylic acid, is an aromatic compound characterized by a vinyl group attached to the para position of benzoic acid. Its vinyl group allows for free radical polymerization, facilitating the formation of various copolymers and hydrogels, making it a versatile monomer in materials science. 4-VBA exhibits good thermal stability, which is essential for applications requiring high-temperature processing and stability. Additionally, 4-VBA can also be modified to enhance its biocompatibility, making it suitable for drug delivery systems and tissue engineering.
Application
4-Vinylbenzoic acid can be used as:
- A capping agent in the preparation of polyrotaxane hydrogels. The incorporation of 4-VBA modifies and enhances the structural integrity and functionality of the resulting hydrogels, rendering them suitable for biological applications.
- A monomer in the synthesis of molecularly imprinted polymers (MIPs). The incorporation of 4-VBA contributes to improved selectivity in MIPs. The study highlights that MIPs synthesized with 4-VBA exhibit significant binding affinity towards specific biomolecules, making them effective for applications such as drug delivery and biosensing.
- A functional monomer in the synthesis of benzoic acid-modified monolithic columns. These columns are suitable for a wide range of applications, including drug analysis and environmental monitoring, where the separation of small, polar molecules is often challenging.
