Background:

Surface modification is crucial for tailoring material properties.
Developing universal methods for functionalizing diverse substrates, including chemically inert ones, remains a challenge.

Purpose of the Study:

To demonstrate a universal approach for growing polymer brushes from various substrates.
To utilize urushiol as a general scaffold for initiator immobilization and subsequent polymer grafting.

Main Methods:

Mixing urushiol with initiator-containing catechol.
Spin-coating or casting the mixture onto various substrates to form a thin film.
Grafting polyelectrolyte poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) polymer brushes onto the immobilized initiator scaffold.

Main Results:

Urushiol films strongly adhered to a wide range of substrates, including chemically inert polyolefins and thermosetting resins.
The initiator-immobilized scaffold exhibited mechanical robustness and chemical inertness.
Grafted poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA) polymer brushes imparted hydrophilicity to the modified surfaces.

Conclusions:

The urushiol-based method provides a universal and robust platform for surface functionalization.
This approach enables the growth of polymer brushes on challenging, chemically inert materials.
The developed technique offers a general strategy for creating functional polymer surfaces for diverse applications.
