Metal-mediated inhibition of CVD polymerization of functionalized [2.2]paracyclophane with a wide range of functional groups is investigated and selective deposition is established for poly(4-vinyl-p-xylylene-co-p-xylylene).

We report the development of multifunctional polymer coatings made by chemical vapor deposition (CVD) copolymerization.

“Smart” materials are materials that undergo dynamic and reversible changes in specific properties in response to certain environmental stimuli. In this perspective, challenges in the field of "smart" materials are highlighted.

Hsien-Yeh Chen, Arthur McClelland, Zhan Chen, Joerg Lahann, "Solventless Adhesive Bonding Using Reactive Polymer Coatings", Analytical Chemistry (2008) 80(11), 4119-4124.

A novel solventless adhesive bonding (SAB) process is reported, which is applicable to a wide range of materials including, but not limited to, poly(dimethylsiloxane) (PDMS). The bonding is achieved through reactions between two complementary polymer coatings, poly(4-aminomethyl- p-xylylene- co- p-xylylene) and poly(4-formyl- p-xylylene- co- p-xylylene), which are prepared by chemical vapor deposition (CVD) polymerization of the corresponding [2.2]paracyclophanes and can be deposited on complementary microfluidic units to be bonded. These CVD-based polymer films form well-adherent coatings on a range of different substrate materials including polymers, glass, silicon, metals, or paper and can be stored for extended periods prior to bonding without losing their bonding capability.


X. Jiang, H.-Y. Chen, G. Galvan, M. Yoshida, J. Lahann, "Vapor-based initiator coatings for atom transfer radical polymerization", Advanced Functional Materials (2008) 18(1), 27-35.

Chemical vapor deposition of [2.2]paracyclophane-4-methyl 2-bromoisobutyrate was prepared on a wide range of materials as initiator coating. Surface initiated atom transfer radical polymerization of a oligo(ethylene glycol) methyl ether methacrylate was demonstrated on these surfaces as model example for the regulations of protein adsorption and cell adhesion.
