1. Definition and Classification of Superhydrophilic Silane Coupling Agents

First, it is essential to define what superhydrophilic silane coupling agents are. Simply put, they are silane coupling agents with superhydrophilic properties, capable of forming a ultrahydrophobic film on surfaces while maintaining the substrate’s hydrophilicity. Based on their structural and functional differences, they can be classified into multiple types, such as amino silane coupling agents, epoxy silane coupling agents, and vinyl silane coupling agents. These variants exhibit distinct performance characteristics due to their unique chemical structures, satisfying diverse application requirements.
