Surfaces Bearing Fluorinated Nucleoperfluorolipids for Potential Anti-Graffiti Surface Properties

Abstract

Graffiti can sometimes be a problem when put in an inappropriate place. We looked at a means to prevent such inconvenience. In this work, we explore the possibility of developing surfaces with controlled wettability. If the paint does not spread, the graffiti does not stay. Here, the synthesis and electrodeposition of original 3,4-ethylenedioxythiophene (EDOT) with perfluorinated nucleolipids (ante approach) is reported. The elaboration of similar surfaces using post functionalization is also described. All the prepared surfaces were then investigated for their roughness, wettability, and morphology. Highly hydrophobic features are reported (θ = 137 • ) and oleophobic properties are also reported (θ = 110 • ) showing real potential for the control of surface wettability and for potential anti-graffiti applications, consequently. The surfaces obtained with the ante approach are rougher and more hydrophobic.

Preparation and Performance of Fluorocarbon Polyurethane Amino Baking Paint for Graffiti-Resistant Whiteboards

“…During this process, XYL was added to reduce viscosity and promote reaction. After 4 h of continuous reaction, fluorocarbon monoisocyanate (HDI-TEOH6) was obtained [19][20][21][22][23].…”

Self-Assembly of Amphiphilic Compounds as a Versatile Tool for Construction of Nanoscale Drug Carriers

“…Interest in these compounds is mostly due to the nitrogenous bases (adenine, uracil, thymine, guanine) inserted in their chemical structure and capable of being involved in additional specific interactions. As an example, nucleolipids was known by their capability to form films at air/liquid interfaces [ 94 ], coatings for surface hydrophobization [ 95 ], liquid crystalline mesophases [ 96 ], as well as they have potential for the design of highly-sensitive sensors for nucleobases [ 97 ] and inorganic ions [ 98 ]. Besides, the specific architecture of nucleolipid molecules and their biocompatibility allows their use for biomedical purposes as neurotracers [ 99 ], drugs against glioblastoma [ 100 ] and carriers for potential anti-malarial drugs [ 101 ].…”

Polysilazane-based coatings: corrosion protection and anti-graffiti properties

“…The chemical changes induced by the different curing conditions have been assessed by means of FT-IR spectroscopy while electrochemical impedance spectroscopy (EIS) has been employed to evaluate the effect on the electrochemical properties. The graffiti resistance has been assessed by means of contact angle measurements [22] and by the determination of the clean-ability according to the guidelines of the ASTM D6578 standard [23].…”
