“…Intrigued by these experiments, we aim to address the following fundamental questions by taking advantage of surface-initiated polymerization (in which initiators can be selectively bonded to a surface to drive the movement and addition of monomers) 20 : Can possibly also organic molecules such as monomers pass through single-layer CVD graphene? If so, what happens to graphene?…”

Polymerization driven monomer passage through monolayer chemical vapour deposition graphene

Mass transport through graphene is receiving increasing attention due to the potential for molecular sieving. Experimental studies are mostly limited to the translocation of protons, ions, and water molecules, and results for larger molecules through graphene are rare. Here, we perform controlled radical polymerization with surface-anchored self-assembled initiator monolayer in a monomer solution with single-layer graphene separating the initiator from the monomer. We demonstrate that neutral monomers are able to pass through the graphene (via native defects) and increase the graphene defects ratio (Raman ID/IG) from ca. 0.09 to 0.22. The translocations of anionic and cationic monomers through graphene are significantly slower due to chemical interactions of monomers with the graphene defects. Interestingly, if micropatterned initiator-monolayers are used, the translocations of anionic monomers apparently cut the graphene sheet into congruent microscopic structures. The varied interactions between monomers and graphene defects are further investigated by quantum molecular dynamics simulations.

“…Different polymer architectures forming polymer “brushes” have been exploited to tune the interfacial physicochemical properties of organic and inorganic materials, and to mediate the way these supports interact or integrate with the surrounding environment . Simultaneous advances in surface‐initiated controlled radical polymerization (SI‐CRP) techniques have provided the synthetic tools for fabricating polymer films with precisely tunable architecture and functionalities, enabling the creation of quasi‐3D polymer interfaces. These included multiblock‐copolymer brushes generating layered films with discrete chemistries and physicochemical properties, brush films featuring covalent or physical crosslinks, and brushes presenting gradient characteristics, such as a gradually varying composition and/or structural properties along a single substrate.…”

The fabrication of polymer brushes via surface-initiated controlled radical polymerizations has progressively developed beyond a simple surface functionalization technique, enabling the design of complex polymer interfaces with a quasi-3D molecular organization. The modulation of polymer brush structure has led to an extremely broad tuning potential for technologically relevant interfacial, physicochemical properties, allowing one to precisely tune swelling, nanomechanical, and nanotribological characteristics of polymer films. In addition, the synthesis of multilayer brush interfaces with hierarchical architecture has been exploited to control biological phenomena on modified platforms, such as cell adhesion and settlement, or to fully prevent biological contamination from bacteria. In this feature article, the most recent developments in the synthesis and application of quasi-3D structured polymer brushes are summarized, placing particular attention on how the tuning of grafted-polymer architecture could translate into a variation of interfacial characteristics.

“…Considering the poor physical properties of physically coated (adsorbed) polymers, chemically grafting polymers with a covalent bond is more desirable. The polymer‐grafted inorganic particles (PGIPs) which can retain optical and mechanical properties of inorganic cores while having the surface properties of polymers are attractive in advanced technologies ranging from drug delivery, enzyme imaging, heavy metal removal, photonics to energy storage . For example, with oil‐miscible polymer shells, poly(lauryl methacrylate)–grafted silica nanoparticles have been demonstrated as effective lubricant additives in poly(alphaolefin) base oils for friction and wear reduction .…”

“…There are basically two strategies that are frequently used to fabricate PGIPs, that is, “grafting onto” and “grafting from.”[2a,d,5] Covalent bond “click” reactions including alkyne–azide, thiol–ene, and thiol–yne, between the end group of polymers and surface functionalized inorganic particles lead to a “grafting onto” strategy . However, the coating thickness is always limited by the steric hindrance, especially for high molecular‐weight precursor polymers.…”

Polymer‐grafted inorganic particles (PGIPs) are attractive building blocks for numerous chemical and material applications. Surface‐initiated controlled radical polymerization (SI‐CRP) is the most feasible method to fabricate PGIPs. However, a conventional in‐batch reaction still suffers from several disadvantages, including time‐consuming purification processes, low grafting efficiency, and possible gelation problems. Herein, a facile method is demonstrated to synthesize block copolymer–grafted inorganic particles, that is, poly(poly(ethylene glycol) methyl ether methacrylate) (PPEGMEMA)‐b‐poly(N‐isopropylacrylamide) (PNIPAM)–grafted silica micro‐particles using continuous flow chemistry in an environmentally friendly aqueous media. Immobilizing the chain transfer agent and subsequent SI‐CRP can be accomplished sequentially in a continuous flow system, avoiding multi‐step purification processes in between. The chain length (MW) of the grafted polymers is tunable by adjusting the flow time or monomer concentration, and the narrower molar mass dispersity (Ð < 1.4) of the grafted polymers reveals the uniform polymer chains on the particles. Moreover, compared with the in‐batch reaction at the same condition, the continuous system also suppresses possible gelation problems.
