Solvent-free Acrylic Pressure-Sensitive Adhesives via an Additive-free Visible-light Driven Photocatalytic Free Radical Polymerization |
초록 |
Solvent-free light-curing acrylic pressure-sensitive adhesives (PSAs) have tremendously grown but mostly prepared in the presence of photoinitiators by high-energy UV-light that causes several issues such as radiation safety. Herein, for the first time, solvent-free acrylic PSAs were prepared through visible-light-driven photocatalytic free radical polymerization. Combined experimental and theoretical studies show that the use of N-vinyl based monomer is essential to enhance the polymerization rate and monomer conversion. Viscoelasticity, mechanical strength and adhesion performance of acrylic PSAs were nicely adjusted in a broad range by controlling the monomer composition, suggesting that our new method would replace the existing photoinitiated free radical polymerization. |
