Confined polymerization: multidimensional regulation, advanced measurements and cutting-edge applications

microscopy, spectroscopy, and computational simulation. Additionally, we discuss confined polymerization in cutting-edge applications, such as water purification, medical diagnosis and treatment, energy storage, catalysis, and composite coatings. By combining fundamental principles with functional innovation, we identify the key challenges, such as real-time mechanism detection and scalable synthesis, and propose future directions, including dynamic limitations, biomimetic design, and AI-driven optimization. The aim of this article is to stimulate the attention of more scholars to the field of confined polymerization, thereby accelerating breakthrough progress in this field and providing innovative material solutions for global challenges such as climate change, disease treatment, and clean energy.
