“…Both with and without CNC addition the coating provided corrosion protection for more than one month in 0.1 M NaCl. [15] Interestingly, with the CNC additive we found an improved corrosion protection performance with time, whereas the typical behavior for barrier coatings of decreasing protective ability with time was found for the matrix alone. [15] Up to now, no studies have been performed to systematically compare the corrosion protection properties of CNC and CNF containing barrier composite coatings, but the present work addresses this issue.…”

[15] Up to now, no studies have been performed to systematically compare the corrosion protection properties of CNC and CNF containing barrier composite coatings, but the present work addresses this issue. We compared the effect of CNC and CNF on the corrosion resistance of a waterborne hydroxyacrylate-based coating in 0.1 M NaCl solution by using electrochemical impedance spectroscopy (EIS).…”

“…Composite coatings containing 0.5 wt.% cellulose additives of total dry mass were prepared as reported for CNC in our previous work. [15] Briefly, 0.2 g of dried CNC powder was added into 100 g of the matrix dispersion. The mixture was magnetically stirred for 2 min at 500 rpm followed by ultrasonication for 2 min.…”

“…A few studies have reported the corrosion protection properties of CNC reinforced composite polymer coatings. [13][14][15] Ma et al used cellulose nanocrystals as additives in epoxy resins and investigated the corrosion protection performance of 60 mm thick barrier coatings using electrochemical impedance spectroscopy (EIS). [13] They found excellent corrosion protection in 3.5 wt.% NaCl for up to 30 days, and the best protective ability was found for an additive concentration of 1.0 wt.%.…”

Nanocomposite coatings are of great interest as barrier coatings since synergy effects between matrix and additive properties can be achieved. This, however, requires favorable additive-matrix interactions to provide a strong interphase (interface region). In this work we elucidate the properties of two environmentally benign nanocomposite coatings based on a waterborne acrylate formulation with additives from renewable sources, i.e. either cellulose nanocrystals, CNC; or, alternatively, cellulose nanofibrils, CNF. We focus on the corrosion protective properties of these coatings and discuss the reason why the nanocomposite with CNC displays favorable corrosion protection properties whereas that with CNF does not. To this end we utilized scanning electron microscopy, water contact angle measurement, Fourier transform infrared spectroscopy and electrochemical impedance spectroscopy techniques to investigate the microstructure, surface wetting, interactions between cellulosic materials and matrix as well as corrosion protective properties of both composite coatings.

Nanocrystalline cellulose is a renewable nanomaterial that has gained huge attention for its use in various applications from advanced biomedical material to food packaging material due to its exceptional physical and biological properties, such as high crystallinity degree, large specific surface area, high aspect ratio, high thermal resistance, good mechanical properties, abundance of surface hydroxyl groups, low toxicity, biodegradability, and biocompatibility. However, they still have drawbacks: (1) sources of raw materials and its utilization in the production of nanocomposites and (2) high chemical and energy consumption regarding the isolation of macro-sized fibers to nano-sized fibers. The incorporation of hydrophilic nanocrystalline cellulose within hydrophobic polymer limits the dispersion of nano-sized fibers, thus resulting in low mechanical properties of nanocomposites. Hence, surface modification on nano-sized fiber could be a solution to this problem. This review focuses on the advanced developments in pretreatment, nanocrystalline production and modifications, and its application in food packaging, biomedical materials, pharmaceutical, substitution biomaterials, drug excipient, drug delivery automotive, and nanopaper applications.

Two‐dimensional (2D) nanomaterials, with extraordinary physical and chemical characteristics, have long been regarded as a promising nanofiller in organic coatings for marine corrosion protection. The past decade has witnessed the high‐speed progress of 2D nanomaterials reinforced organic composite coatings, and plenty of breakthroughs have been achieved as yet. This review covers an in‐depth and all‐around outline of the up‐to‐date advances in 2D nanomaterials modified organic coatings employed for marine corrosion protection realm. Starting from a brief introduction of 2D nanomaterials, with the preparation strategies and properties is illustrated. Subsequently, diverse protection models based on composite coatings for marine corrosion protection are also introduced, including physical barrier, self‐healing, as well as cathodic protection, respectively. Furthermore, computational simulations and critical factors on the corrosion protection properties of composite coatings are clarified in detail. Finally, the remaining challenges and prospects for marine corrosion protection based on 2D nanomaterials reinforced organic coatings are highlighted.This article is protected by copyright.
