Abstract Antifouling epoxy resin serves as a member of advanced nanocomposite coatings and engineered surfaces. Nevertheless, developing an antifouling composites is state‐of‐the‐art technology. Herein, complex nanostructure tailored to be served additive giving the characteristics resin. F‐POSS@HNT hybrid nanostructure, that is, halloysite nanotubes (HNTs) decorated with fluorinated polyhedral oligomericsil sesquioxane (F‐POSS), was synthesized characterized. Chemical structure changes,...

Abstract A novel fluorinated thermoplastic (FT) was synthesized from diglycidyl ether of bisphenol (DGEBA), and 3‐(trifluoromethyl)aniline. FT found to be miscible with DGEBA as shown by the existence a single glass transition temperature ( T g ) within whole composition range. On basis several experimental techniques, it that upon heating etherification reaction takes place between DGEBA. DGEBA‐aromatic diamine (4,4′‐methylenebis(3‐chloro 2,6‐diethylaniline) formulation modified FT. The...

ABSTRACT Halloysite nanotubes (HNTs) have attracted a technologic and scientific attention as reinforcements of epoxy‐based nanocomposites. However, their reported interaction with epoxy matrices is varied the controlled dispersion HNTs still challenge. In this work, we study effect chemical reactions taking place in process halloysite possible influence composite's properties. HNTs' surface was modified through an alkaline treatment by grafting two aminosilanes different chain lengths...

ABSTRACT The influence of the surface chemical modification on bulk behavior epoxy based networks has been studied. In particular, dynamics epoxy‐amine modified with fluorinated side chains characterized by means broadband dielectric spectroscopy (BDS), differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy. fluorination effect structure materials related observed changes in both segmental secondary relaxations. An acceleration as degree increases clearly...

Abstract Summary: Fluorinated polyurethane films were obtained from 5‐isocyanato‐1‐(isocyanatomethyl)‐1,3,3‐trimethyl‐cyclohexane (IPDI) and polyethylene oxide (PEO), employing two monoalcohols with different chain lenghts as fluorinated modifiers, 1H,1H,2H,2H‐tridecafluoro‐1‐n‐octanol (EA600) 1H,1H,2H,2H‐heptadecafluoro‐1‐n‐decanol (EA800). X‐ray photoelectron spectroscopy (XPS) has demonstrated that fluorine surface enrichment takes place. Atomic force microscopy (AFM) was employed in...

Abstract Two series of trifluoromethylated crosslinked epoxy‐based polymers with different molecular architectures and fluorine contents (from 1 to 5 wt%) have been investigated. The epoxy monomer was a diglycidyl ether bisphenol A, the curing agents were 3‐(trifluoromethyl)aniline 4,4′‐methylenebis(3‐chloro‐2,6‐diethylaniline). structural parameters networks such as gelation vitrification properties resulting fluorinated materials investigated compared. Final showed high transparency an...

Abstract Developing multifunctional epoxy composites with tailored properties supports energy systems, especially oil and gas industries. We report synthesis of 3D fluorinated‐polyhedral oligomeric silsesquioxanes (F‐POSS) nanoparticles (NPs) co‐condensed on the surface 2D sepiolite (SEP) nanoclays, dispersed it within an resin to facilitate curing kinetics epoxy‐amine system. A catalytic effect was realized, supporting excellent cure index, according kinetic models employed. Friedman model...

Recently developed low fluorine containing polymers are advanced materials which confer advantageous properties to surfaces at a lower cost than conventional fluoropolymers (like PTFE), and also more easily processable. Fluoropolymer characterized by surface energy, high oleo hydrophobicity, coefficients of friction, among many other properties. This makes them desired in microelectronics, antifogging, antifouling medical applications, name few. Fluorinated compounds not coupled with...
