Abstract: The reproducibility of polymer brush synthesis via surface‐initiated controlled radical polymerization is interrogated. Experiments compare the stability of initiating monolayers for surface‐initiated (SI) reversible addition‐fragmentation chain transfer polymerization (SI‐RAFT) and SI atom transfer radical polymerization (SI‐ATRP). Initiator‐functionalized substrates are stored under various conditions and grafting densities of the resulting polymer brush films are determined via in situ ellipsometry. Decompo… Show more

“…Expanding on oxygen-tolerant PET-RAFT in aqueous solutions by Boyer and co-workers , and guided by our previous work on a DMSO-based SI-PET-RAFT system, , Figure shows a schematic of the newly aqueous SI-PET-RAFT system developed in this work and an example of the performance of the resulting polymer brush film as an anti-fogging coating. As a general procedure, glass surfaces were modified with RAFT chain transfer agents (CTAs).…”

“…The versatility of this approach is highlighted by its monomer scope, including various acrylates, acrylamides, and methacrylates of neutral, cationic, anionic, and zwitterionic nature not demonstrated to polymerize by our previous SI-PET-RAFT work employing organic solvents. , Table illustrates the broad monomer scope accessible for this surface-initiated system, initial growth rates, film thicknesses after 60 min of polymerization, and water contact angles (WCAs, θ) for the final films. Triethoxysilane-functionalized 2-(dodecylthio­carbonothioylthio)-2-methyl­propionic acid (DDMAT) and cyano-4-[(dodecylsulfanyl­thiocarbonyl)­sulfanyl]­pentanoic acid (CDTPA) derivatives were used as surface-tethered RAFT CTA initiating monolayers.…”

“…In agreement with previous findings for SI-PET-RAFT, CzBA polymer brush height/thickness vs.time initially increases linearly and subsequently plateaus (Figure 2a). [12,13,[48][49][50] This is aresult of the presence of free CTAi nt he reaction solution, forming bulk polymer,i ncreasing solution viscosity,a nd reducing monomer diffusion to the growing chain end at the surface. [12] Notably,the oxygen tolerance of this approach is anticipated to be particularly advantageous for commercial manufacturing of these materials,a sc onventionally the requirement for strictly inert conditions imposes additional complexity and expense.…”
