Poly(4-vinylphenol) is widely used as a key material in the electronics industry, particularly in the fabrication of organic thin-film transistors (OTFTs) and other electronic devices. Its excellent film-forming properties and dielectric characteristics make it suitable for use as an insulating layer in these devices, enhancing their performance and stability.

In the field of coatings, it is employed as a binder or resin due to its high thermal stability and adhesion properties. It is often used in protective coatings for metals, plastics, and other surfaces, providing durability and resistance to environmental factors.

Additionally, poly(4-vinylphenol) finds applications in the development of sensors and biosensors. Its ability to form stable films and interact with various analytes makes it a valuable component in detecting gases, chemicals, or biological molecules.

In advanced materials research, it is utilized as a precursor or component in the synthesis of functional polymers and nanocomposites, contributing to the development of innovative materials with tailored properties for specific applications.
