Application of hydroxyethyl methacrylate

(HEMA)Hydroxyethyl methacrylate (HEMA) is an important hydrophilic monomer, which contains hydroxyl (-OH and methacrylate groups in its structure. Due to its excellent hydrophilicity, biocompatibility, and polymerizability, HEMA has been widely used in various fields, in optical materials and biomaterials, as follows. 

1. Contact lenses: The high hydrophilicity and high water content (usually 38%-60%) of HE can effectively reduce dryness during the wearing of contact lenses, providing a comfortable wearing experience, and it is the main raw material for manufacturing soft contact lenses. 

2.  Artificial lenses For manufacturing high-transparency, biocompatible artificial lenses, it can effectively reduce postoperative inflammation and improve visual quality.

3.  Drug sustained release system: HEMA is to prepare drug carriers to achieve controlled drug release. It is suitable for ophthalmic drug sustained release system (such as for glaucoma treatment).

Hydroxyethylacrylate (HEMA), as an important hydrophilic monomer, has shown broad application prospects in contact lenses, artificial lenses, drug sustained release systems, tissue engineering other fields. Through modification and innovation, HEMA will play a more important role in the future of materials science and biomedicine. In the future, we will develop HE derivatives with higher oxygen permeability and resistance to protein adsorption. At the same time, we will pay more attention to intelligence and environmental protection, and study intelligent HEMA materials that to environmental stimuli (such as pH, temperature). Develop environmental-friendly synthetic processes to reduce the impact on the environment.
