“…[5] The presence of the reactive anhydride group in MAPP films makes possible its uses for surface functionalization and adhesion improvement, [6][7][8][9][10] biocompatibility and biomedical applications, [11][12][13][14] and development of (nano) patterned surfaces. [15,16] Since the concentration of anhydride groups is the most important criterion to define the application of the MAPP films, previous studies have focused on chemical characterization of the polymer surfaces in specific conditions for which the concentration of the anhydride group is high. However, little attention has been given to the effect of the plasma polymerization parameters on the morphology of the MAPP films.…”

We report for the first time the formation of spherical and branched structures when polymerizing maleic anhydride under very low power with pulsed plasma polymerization. A factorial experimental design evidenced duty cycle, frequency and their interactions as decisive factors for the formation and growth of these structures. A mechanism involving the decoupling of deposition (nucleation) and diffusion rates of active species was proposed to relate structure formation to processing parameters. While differences in surface chemistry were not detectable by surface spectroscopy (PM‐IRRAS, XPS), AFM force measurements on a carefully designed sample evidenced differences in adhesion and thus surface chemistry between the different film morphologies.

“…Our group previously studied plastic substrates dip-coated with a functional polymer solution and succeeded in introducing reactive groups on the outermost surface. − However, surface functionalization based on the dip-coating approach is irreversible and not well suited for micropatterning without lithography. Reversible surface functionalization is generally termed “rewritable,” − and this process can enable erasable information storage and reduce plastic wastes. Micropatterning without lithography allows for surface functionalization of designated surface areas of objects with complicated structures.…”

Fluorous chemistry has unique features and high potential applicability, which are distinct from those of nonfluorinated organic compounds. However, there are limited reports detailing the applications of fluorous−fluorous interactions (fluorophilicity or fluorous affinity), likely because these interactions are not found in nature. In the present study, we describe the rewritable surface functionalization of a plastic substrate based on fluorous affinity. Plastic substrates were dip-coated with a series of methacrylate-based fluoropolymers to generate fluorous surfaces. Fluorous-tagged small molecules [perfluoroalkyl (Rf) amines] were immobilized on the fluorous surfaces via fluorous−fluorous interactions, thereby introducing reactive functional groups (amino moieties) on the surface. The amino groups displayed on the surface (accessible by a reactant) were successfully quantified using a reactive fluorophore, which enabled quantitative analysis of the Rf-amines immobilized on the fluorous surface that were available for the subsequent reaction. The effects of the molecular structures of the fluoropolymers and Rf-amines on the surface immobilization of Rf-amines were also investigated quantitatively. The surface coated with a fluoropolymer containing −C 8 F 17 most effectively immobilized an Rf-amine comprising two −C 6 F 13 chains. The adhered Rf-amines were easily removed by washing the surface with methanol, and then, they could successfully be reimmobilized on the surface. Finally, the presented approach enabled the rewritable micropatterning of an Rf-tagged biomolecule on a plastic surface through microcontact printing.

“…The interest of maleic anhydride plasma polymer (MAPP) thin films is due to the high degree of retention of anhydride groups associated with their noteworthy reactivity (numerous potential post‐modification possibilities), the numerous structures potentially formed (beads, needle‐like, branched, or rod‐shaped structures), and the growth kinetics that can be finely controlled by playing with various experimental plasma parameters (monomer flow rate, input energy, modulated pulse time). [ 17–20 ] As a consequence, the deposition of MAPP makes possible the surface functionalization of materials for controlled nanopatterning, [ 21,22 ] adhesion improvement, [ 23–27 ] biocompatibility, and biomedical applications. [ 28–32 ]…”

The impact of surface chemistry on the morphogenesis of maleic anhydride plasma polymer is investigated on silicon wafers with very well‐controlled surface chemistries (i.e., native oxide, hydroxyl‐rich, and alkyl‐rich). A particular attention is paid to characterize the early stages of growth. Two different morphologies of polymer films are obtained, depending on the hydrophilic or hydrophobic nature of the substrate surface, even though the chemical composition is very similar. Homogeneous and dense polymer films are formed on hydrophilic substrates due to the strong affinity of plasma species toward the surface. Elongated nanostructures resulting in a less dense polymer film grow on the hydrophobic surface, which are assumed to be the result of the low affinity of plasma species.
