“…Enthused by natural sources, synthetic super-hydrophobic materials are extensively created by combining low surface free energy materials with appropriate nano and micro structures. Organo-silane [14][15][16][17], uoro-polymer [18][19][20][21], uoro-silane [22][23], long alkyl spacer [5,[24][25][26], SiO 2 nanoparticles [3][4][5][25][26][27][28], graphene [29][30][31], and polybenzoxazine [1-5, 24, 25] are extensively alarmed sorts of materials with lower value of surface energy and are agreed to construct super-hydrophobic surfaces in the industry and academia for various applications.…”

In this work, an effort has been made to develop silane functional cardanol based polybenzoxazine-silica hybrid material for high thermal, flame resistant, super hydrophobic and oil-water separation applications. Silane functional cardanol based benzoxazine (C-aptes) monomer is synthesized using cardanol, 3-aminopropyltriethoxysilane (APTES) and paraformaldehyde through Mannich condensation reaction. Later, C-aptes and various weight percentages (0, 25, 50, 75, 100 wt. %) of tetraethylorthosilicate (TEOS) solution is coated on cotton fabric/ or filter paper and polymerized via thermal induced ring opening polymerization. The developed Poly(C-aptes)-silica hybrid materials are utilized to check their molecular structure, thermal, flame resistant, hydrophobic, oil-water separation properties. Data attained from thermal, flame resistant, and hydrophobic studies, conferred that the prepared eco-friendly hybrid poly(C-aptes)-silica revealed higher properties with superior oil-water separation behaviour over the neat PBZ matrices. Consequently the developed sustainable bio-based poly(C-aptes)-silica hybrid materials will be able to useful in hydrophobic coatings and oil-water separations.

“…17 It is well known that fluorinated polymers are characterized by low surface free energy and high water contact angle. [18][19][20][21] Moreover, epoxy resin modification methods using fluorinated compounds also are described. 22,23 Few articles present a correlation between chemical structure of fluorinated epoxy resins and ice adhesion properties, which is very important in the case of materials with low ice adhesion preparation for antiicing applications.…”

Resins have been widely used in a variety of industry fields for more than a century, such as coatings, adhesives, or automotive. Their low cost and workability are extremely useful in creating more and more advanced materials due to their chemical structure (Ghaffari et al. in Surf Interfaces 17:100340, 2019). Common problem today is the wetting tendency of various materials which in the end can result in further damage in the structure because of atmospheric conditions. Nowadays, scientists are trying to find better ways to improve the properties of coatings or composites in cases like hydrophobicity or icephobicity. One of the examp les are fluorinated organic compounds with good linking properties to the substrate (Qin et al. in Mater Today Commun 22:100770, 2020). Because o f that, to im prove the properties of a basic epoxy resin, its chain has been modified with hydrophobic compounds with different chain lengths. Influence of modifiers’ molecule size on hydrophobic and ice adhesion properties of obtained epoxy resins has been tested. Chemical composition of prepared coatings was analyzed by FTIR. Moreover, their thermal stability was investigated using TG and DSC measurements. Additionally, wettability of the samples was analyzed with a goniometer. Furthermore, their ice adhesion tests were performed on a dedicated apparatus. As a result, presented work provides a critique overview and concept of promising icephobic and hydrophobic coatings in the industry. Moreover, these products have a high chance to be developed further.

“…Hydrophobic surfaces have been constructed on various materials, including polymers, metals, and fibers, these new functional materials are widely used in template, filtration, biology, optoelectronics, bionic materials, and other fields. [1][2][3][4] A number of researchers have reported that the wettability of solid surface is determined by chemical composition and microstructure. [5][6][7] Silicones and fluoroalkyl polymers with low surface free energy can provide hydrophobic function.…”

We constructed a coating with controllable microstructure on the substrate by static breath figure (BF) method. In the atmosphere of water, when the fluorine‐containing 1H,1H,2H,2H‐perfluorooctyl polyacrylate‐block‐polystyrene copolymer (PTFOA‐b‐PS (4 h)) synthesized via atom transfer radical polymerization for 4 h was dissolved in carbon disulfide (CS2) and then coated on the silicon wafer, the concentrated pore size and uniform micro‐pore structure was successfully constructed on the surface. However, the hydrophobicity of the resulting microporous coating was not so good. An interesting result is that when the copolymer solution of PTFOA‐b‐PS (2 h) in tetrahydrofuran (THF) was used under the MeOH/H2O atmosphere (the methanol content was 60% or 80%), the microsphere coating can be produced on the substrate surface to obtain the excellent hydrophobicity. The water contact angles (WCAs) were 148.8 ± 1.8° and 150.3 ± 1.8°, respectively. Energy dispersive X‐ray spectrometer (EDS) results showed that the fluorine element was enriched in the outerfield of the microsphere coating. The low surface energy of fluorine combined with the rough and complex structure of the microspheres can effectively improve the hydrophobicity of the coating.
