“…In this case, cellulose fibers with nano-scale width might be attractive due to their environmental advantages and extraordinary mechanical properties such as stiffness, high Young's modulus and tensile strength [10][11][12]. Among the several procedures for preparing nanocellulose, the acid hydrolysis is the most well-known and commonly used.…”

“…Poaty et al (2014) implemented the modification of cellulose nanocrystals with various acryloyl chlorides as reinforcement derivatives for wood coatings, which resulted in an enhanced abrasion resistance of the coatings. Satyamurthy and Vigneshwaran (2013) studied the novel process of preparing spherical NC using anaerobic microbial hydrolysis with MCC and found that the bimodal particle formed by NC has potential in commercial applications. Shankar and Rhim (2016) prepared NC from MCC using an alkaline dissolution method, followed by the regeneration of cellulose, neutralization, and ultrasonication, which decreased the material to the nano-size level as a result.…”

Nanocellulose (NC) is an attractive reinforcement agent that can be incorporated into protective coatings because it is a renewable, biodegradable, and biocompatible polymer resource. In this study, a series of epoxy resin-based nanocomposites were prepared in the form of coatings with various amounts of NC loadings, and the coatings were applied onto mild steel at room temperature. The characterizations of the NC and nanocomposites were performed via X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and Fourier transform infrared spectroscopy (FTIR). The thermophysical properties of the nanocomposites were evaluated using differential scanning calorimetry (DSC) and thermogravimetry (TGA) analyses. The transparency of the nanocomposite specimens was examined by ultraviolet visible (UV-Vis) spectroscopy in the range of 300 to 800 nm. The corrosion protection properties of the coated mild steel substrates immersed in a 3.5% NaCl solution were studied comparatively by electrochemical impedance spectroscopy (EIS). The results showed that all of the nanocomposite coatings with NC noticeably influenced the epoxy-diamine liquid pre-polymer, both physically and chemically. Furthermore, the 1 wt.% NC nanocomposite coating system was found to have the most pronounced anti-corrosion properties, as confirmed by a 30-day EIS study.

“…Satyamurthy and coworkers prepared CNC with a yield of 22% [5], whereas the same group reported a maximum yield of~12% using an anaerobic microbial consortium [7]. In contrast, Filson et al [6] studied the enzymatic hydrolysis of recycled paper using endoglucanases, following by microwave or conventional heating to produce related materials.…”

Nanocellulose has been used with promising results as reinforcement material in composites, many of which include hydrophobic polymers. However, the hydrophilic nature of nanocellulose can be better exploited in composites that incorporate high surface energy systems as well as in applications that can benefit from such properties. In fact, proteins can be ideal components in these cases. This paper reviews such aspects, which are based on the remarkable mechanical properties of nanocellulose. This material also exhibits low density, high aspect ratio, high surface area, and can be modified by substitution of its abundant hydroxyl groups. It also shows biocompatibility, low toxicity, and biodegradability. Convenient biotechnological methods for its production are of interest not only because of the possible reduction in processing energy but also because of positive environmental aspects. Thus, enzymatic treatments are favorable for effecting fiber deconstruction into nanocellulose. In addition to reviewing nanocellulose production by enzymatic routes, we discuss incorporation of enzyme activity to produce biodegradable systems for biomedical applications and food packaging. Related applications have distinctive features that take advantage of protein-cellulose interactions and the possibility of changing nanocellulose properties via enzymatic or protein treatments.
