Issue Date: | 2018 | Source: | CHEMICAL COMMUNICATIONS, 54 (7), p. 751-754 | Abstract: | A 2D laser lithography protocol for controlled grafting of polymer brushes in a single-step is presented. A series of polyacrylates were grafted from silicon substrates via laser-induced copper-mediated radical polymerization. Film thicknesses up to 39 nm were reached within 125 μs of exposure to UV laser light (351 nm). Successful block copolymerization underpinned the controlled nature of the grafting methodology. The resolution of a small structure of grafted PHEA reached 270 μm and was limited by the type of laser used in the study. Further, a checkerboard pattern of PtBA and POEGA was produced and imaged via time-of-flight secondary ion mass spectrometry (ToF-SIMS), and X-ray photoelectron spectroscopy (XPS). | Notes: | Junkers, T (reprint author), Univ Hasselt, Inst Mat Res IMO, Polymer React Design Grp, Martelarenlaan 42, B-3500 Hasselt, Belgium. christopher.barnerkowollik@qut.edu.au; tanja.junkers@uhasselt.be | Keywords: | 2D laser lithography; photoinduced copper-mediated radical polymerization; reversible deactivation radical polymerization | Document URI: | http://hdl.handle.net/1942/25575 | ISSN: | 1359-7345 | e-ISSN: | 1364-548X | DOI: | 10.1039/c7cc08444g | ISI #: | 000422989400011 | Rights: | This journal is © The Royal Society of Chemistry 2018 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2019 |
