“…The gradual emergence of hydrophilic contents leads to surface heterogeneity by lowering duty cycle causing an increased surface adhesion in hydrophobic coatings. The C 4 F 8 -co-AA plasma polymer coatings on the nanotextured surfaces are tuned from repulsive superhydrophobicity to adhesive superhydrophobicity, and further to superhydrophilicity by adjusting the duty cycles with the monomer feed rates [115].…”

Inspired by nature, tunable wettability has attracted a lot of attention in both academia and industry. Various methods of polymer surface tailoring have been studied to control the changes in wetting behavior. Polymers with a precisely controlled wetting behavior in a specific environment are blessed with a wealth of opportunities and potential applications exploitable in biomaterial engineering. Controlled wetting behavior can be obtained by combining surface chemistry and morphology. Plasma assisted polymer surface modification technique has played a significant part to control surface chemistry and morphology, thus improving the surface wetting properties of polymers in many applications. This review focuses on plasma polymerization and investigations regarding surface chemistry, surface wettability and coating kinetics, as well as coating stability. We begin with a brief overview of plasma polymerization; this includes growth mechanisms of plasma polymerization and influence of plasma parameters. Next, surface wettability and theoretical background structures and chemistry of superhydrophobic and superhydrophilic surfaces are discussed. In this review, a summary is made of recent work on tunable wettability by tailoring surface chemistry with physical appearance (i.e. substrate texture). The formation of smart polymer coatings, which adjust their surface wettability according to outside environment, including, pH, light, electric field and temperature, is also discussed. Finally, the applications of tunable wettability and pH responsiveness of polymer coatings in real life are addressed. This review should be of interest to plasma surface science communality particularly focused controlled wettability of smart polymer surfaces.

“…The discovered phenomenon can be used for the spatially controlled attachment of biomolecules that carry net positive charges when in solution at a neutral pH. LSZ have often served as positively charge model proteins, and here, we tested LSZ adsorption onto the nanocomposite samples (50 nm pPEO/submonolayer of ppAA NPs/3 nm capping layer of ppPEO) by in situ liquid‐cell AFM.…”

“…Mixing AA with other monomers was also investigated to produce thin films with variable chemical compositions . Such plasma copolymerization allows fluorocarbons, hydrocarbons, amine‐containing species, and other moieties to be added to the deposited film and produces coatings with unconventional chemistries that can be controlled by the ratio of the supplied precursors.…”

Carboxyl-enriched nanoparticles are produced by the plasma polymerization of acrylic acid (ppAA NPs), whereas plasma-assisted vapor-phase deposition is used to prepare thin films of poly(ethylene oxide) (ppPEO). Sequential depositions generate phase-separated coatings. The ppAA NPs are found to be in a glassy state, whereas thin films of ppPEO are found to be in a rubbery state. When immersed into a solution of lysozymes, the ppPEO absorbs water, which results in the dissociation of the carboxyls on the ppAA NP surface. Negatively charged carboxyls attract positively charged lysozymes. The ppPEO surface in between the NPs resists the accumulation of the protein, leading to the spatially localized adsorption of lysozymes only on the spots where the ppAA NPs are located.
