“…Further, the introduction of PETMP improves the crosslinking density of the coating, which reduces the arrival time of NaCl to the metal surface. The excellent adhesion on metal of the PTUBAF makes it a good barrier for the metal, [40] which protects the metal from the corrosion of NaCl. After immersed in artificial seawater for 144 h, the Q235 steel plate coated with PDMS was almost all corroded, while the Q235 steel plate coated with PTUBAF coating was less corroded, which illustrated the better anti‐corrosion property of the PTUBAF (Figure S11).…”

Poly(dimethylsiloxane) (PDMS) is widely used in marine antifouling coatings due to its low surface energy property. However, certain drawbacks of PDMS coatings such as poor surface adhesion, weak mechanical properties, and inadequate static antifouling performance have hindered its practical applications. Herein, condensation polymerization is utilized to prepare PDMS‐based polythiamine ester (PTUBAF) coatings that consist of PDMS, polytetrahydrofuran (PTMG), 2, 3, 5, 6‐tetrafluoro‐1, 4‐benzenedimethanol (TBD) as the main chains and isobornyl acrylate(IBA) as the antifouling group. The surface adhesion to the substrate is enhanced due to the hydrogen bond between the coated carbamate group and the hydroxyl group on the surface of the substrate. Mechanical properties of PTUBAF are significantly improved due to the benzene ring and six‐membered ring biphase hard structure. The strong synergistic effect of bactericidal groups and low surdace energy endows the PTUBAF coating with outstanding antifouling performance. Due to the low surface energy surface, the PTUBAF coatings are also found to possess excellent anti‐corrosion. Furthermore, since the PTUBAF coatings exhibit a visible light transmittance of 91%, they can applied as protective films for smartphones. The proposed method has the potential to boost the production and practical applications of silicone‐based coatings.

“…The mechanical and chemical combination techniques and features of multiple polymers are of great industrial and academic significance for coating performances because they provide a useful method for modifying properties to achieve the specified application. [1][2][3][4][5] Interpenetrating polymer networks (IPNs), among the different types of polymeric mixtures, are a specific group of hybrid polymer materials comprising two thermosetting resins in which the polymer networks are physically and permanently linked together via chain entanglements, as well as chemically a few bond formations between two resins. [6][7][8][9][10][11][12] Thermosetting resins similar to vinyl ester, polyester, and especially epoxy are generally applied as coating binders.…”

This study investigated the synergistic effects of hybrid graphene nanoplatelet (GnP)/multi walled carbon nanotube (MWCNT) nanofillers at various loadings on the kinetics of curing of the epoxy (EP)/vinyl ester (VE) interpenetrating polymer network (IPN) system, with a mass ratio of 1:1. Fourier transform infrared spectroscopy (FTIR), dynamic mechanical thermal analyzer (DMTA) and differential scanning calorimetry (DSC) were used to monitor the interpenetration process of EP and VE and likely interactions between the components of the different resin systems in IPN. The curing behavior of all prepared samples under non‐isothermal conditions was studied using DSC at four heating rates. Two different isoconversional approaches were applied to evaluate the reaction kinetics, that is, the Friedman and the advanced Vyazovkin methods. The obtained activation energy curves for all samples revealed a complex curing behavior involving three stages; early IPN stage, IPN growth stage, and late IPN stage. Then, the activation energy values for each reaction step were determined based on the Friedman method. The presence of GnP/MWCNT nanoparticles showed no catalytic effect on the reaction of VE with methyl ethyl ketone peroxide (MEKP). In contrast, incorporating GnP/MWCNT nanoparticles significantly decreases the activation energy values of the reaction of ring opening of epoxides with methyl tetrahydrophthalic anhydride (MTHPA) 1‐methyl imidazole (‐Mi) and the reaction of esterification of the hydroxyl groups of VE with MTHPA.Highlights Model‐free methods used to curing study of epoxy‐vinyl ester IPN nanocomposites FTIR, DSC and DMTA used for evaluation IPN formation of EP/VE It showed that the improvement of dispersion and compatibility by using of GnP/MWCNT hybrid Frideman and Vyazovkin methods used to calculate Ea of nanocomposites DSC thermograms were deconvoluted into three individual peaks.

“…[20] As a result, IPNs emerged as highly intriguing materials that have garnered considerable interest across drug delivery, [21] electronics, [22] tougheners, [23] and coatings. [24] However, IPNs will be fatigued, microcracks, or even fractured when undergo frequent energy absorption and dissipation.

Interpenetrating polymer networks (IPNs) possessing a wide damping temperature range are commonly employed as damping materials that have been applied in numerous fields. But IPNs will gradually appear to fatigue microcracks and fracture when long‐term in the energy absorption and dissipation. So, the ability for IPNs to recover from damage is necessary which can considerably prolong their service life. Based on polyurethane (PU) elastomer and cross‐linked epoxy (EP), several innovative self‐healing interpenetrating polymer networks (IPNs) were designed and prepared in this research. The IPNs containing dynamic disulfide bond exhibit favorable damping and self‐healing properties. In detail, the loss factor of IPN‐80/20 is beyond 0.3 at temperatures between ‐0.8°C to 65.5 °C which covers the operating temperature range at room temperature. What is more, The PU/EP IPNs also have excellent shape memory properties, self‐healing ability, and thermal stability.This article is protected by copyright. All rights reserved
