Facile Fabrication of Superhydrophobic Surface from Fluorinated POSS Acrylate Copolymer via One-Step Breath Figure Method and Its Anti-Corrosion Property

Abstract

Novel fluorinated polyhedral oligomeric silsesquioxane (POSS) acrylic copolymers were synthesized by the radical solution polymerization. The superhydrophobic coating was prepared using a one-step breath figure method. Chemical constitution, morphology, hydrophobicity, and anticorrosion ability of as-prepared coatings were investigated by the corresponding equipment. The addition of proper fluorinated POSS can synchronously promote the formation of the micro-nano convex structure and the enrichment of fluorinated groups on the surface. Compared to commercial acrylic coating, the fluorinated POSS coating presented enhanced anticorrosion performance. The impedance was the highest and the corrosion current density was the lowest for superhydrophobic coating with 25 wt % fluorinated POSS.

SiO2/Ladder-Like Polysilsesquioxanes Nanocomposite Coatings: Playing with the Hybrid Interface for Tuning Thermal Properties and Wettability

“…POSS have been widely utilized for the fabrication of hydrophobic surfaces and coatings, by virtue of their versatile features and of the possibility to easily covalently link them to polymer backbones [41][42][43][44][45]. In particular, the polyhedral structure and the high number of tunable peripheral functionalities enable us to increase the surface roughness and decrease the surface energy, simultaneously [43][44][45][46][47][48][49]. The majority of the studies in the field rely on the synthesis and modification of POSS structures with low-surface energy substituents (e.g., fluoroalkyl, alkyl groups, etc.)…”

“…The majority of the studies in the field rely on the synthesis and modification of POSS structures with low-surface energy substituents (e.g., fluoroalkyl, alkyl groups, etc.) and on their exploitation as building blocks or fillers in conjunction with polymers for the production of nanocomposite coatings with improved hydrophobicity [43][44][45]. However, as already mentioned, the use of fluoroalkyl substituents raises environmental and safety concerns and their substitution with more economical and environmentally friendly materials is required [21].…”

Polypropylene/Lignin/POSS Nanocomposites: Thermal and Wettability Properties, Application in Water Remediation

“…The modification of the blended sponge with POSS is based on the interaction between the POSS molecule and the hydroxyl groups in lignin, which was proven by the disappearance of the peaks of hydroxyl groups in the range of 3400–3600 cm −1 . This indicated that lignin and POSS were successfully incorporated into the composites [ 52 , 53 ].…”

A Novel Electroactive Imide Oligomer and Its Application in Anticorrosion Coating

“…All the corrosion parameters including corrosion potential (Ecorr), corrosion current density (Icorr), polarization resistance (Rp), corrosion rate (CR), anodic Tafel slope (ba) and cathodic Tafel slope (bc) are summarized in Table 2. Generally, a higher value of Ecorr and Rp, as well as lower values of Icorr and CR, implied better corrosion protection [34,44,52,53]. Figure 5a shows that bare CRS had the lowest Ecorr (−0.89 V) and the highest Icorr (2.52 × 10 −6 A cm −2 ).…”
