h-BN decorated with Fe3O4 nanoparticles through mussel-inspired chemistry of dopamine for reinforcing anticorrosion performance of epoxy coatings

Functionalized boron carbide for enhancement of anticorrosion performance of epoxy resin

“…Additional new absorption peaks at 1192 and 1042 cm −1 are ascribed to the Si─CH 2 ─R stretch vibration and Si─O─C stretch vibration. These above peaks ought to derive from the grafting of the epoxy functionalized silane KH560 . More notably, the absorption peak at 840 cm −1 corresponds to the unsymmetrical stretch vibration of the epoxy group from the KH560, proving that the KH560 was successfully introduced to the B 4 C.…”

“…In this regard, Inorganic particles have received significant attention as epoxy resin fillers and showed superior barrier properties even at low concentrations . Thus, incorporated inorganic materials can protect the epoxy coating from aggressive species and enhance corrosion protection . There are various reports concerning that improving anticorrosion performance of coatings use inorganic particles such as SiC, graphene oxide, carbon nanotubes, and graphite nanoplatelets …”

“…In this regard, we used silane coupling agent to modify the surface of B 4 C to improve the interaction with epoxy resin. Silane coupling agents have often been used to pretreat the surfaces of inorganic particles to enhance bonding with the polymer matrix . Silanols (Si─OH) can be produced by the hydrolysis reaction of Si‐(OR) 3 groups in silane coupling agents, which then react with the inorganic substrate.…”

CoAl2O4/Kaoline Hybrid Pigment Prepared via Solid-Phase Method for Anticorrosion Application

“…However, the relevant application of some commercial available inorganic pigments is limited due to their disadvantages, such as poor adhesive force and optical transparency, weak abrasion and scratch resistance performance (Zhou et al, 2002; Cayton and Sawitowski, 2005; El-Wahab et al, 2009). Therefore, many attempts have been carried out to prepare high-performance pigments with good anticorrosion properties by designing lamellar-based nano-materials preventing water, oxygen, or ions from penetrating film (Kalendová et al, 2008; Ahmed et al, 2012; Ammar et al, 2016; Zhang et al, 2016). …”

Surface modification of boron nitride by bio‐inspired polydopamine and different chain length polyethylenimine co‐depositing

“…In the past decade, mussel-inspired chemistry has become a popular topic in surface science thanks to its versatility, universality, and simplicity. 22 The self-polymerization of DA and its relevant polydopamine (PDA) mechanism was first reported by Messersmith et al, 23 and then the materials modified by DA have been applied in various domains such as water treatment, energy storage, and biomedicine. As a famous "bio-glue," DA can be simply attached to the surface of nearly any substrates by self-polymerization in a weak alkaline solution.…”
