“…Recent results focus on applications in the area of packaging [149,150], water absorption [151] and supercapacitors [152,153], as well as optical devices [154][155][156][157][158][159][160]. In such applications, either BNC itself is reinforced by additives [161][162][163][164] or BNC serves as the reinforcing material, e.g., for synthetic polymers [165,166]. Another aim of current research is the enhancement of BNC properties to get softer and more flexible materials [167].…”

Nanocelluloses are natural materials with at least one dimension in the nano-scale. They combine important cellulose properties with the features of nanomaterials and open new horizons for materials science and its applications. The field of nanocellulose materials is subdivided into three domains: biotechnologically produced bacterial nanocellulose hydrogels, mechanically delaminated cellulose nanofibers, and hydrolytically extracted cellulose nanocrystals. This review article describes today's state regarding the production, structural details, physicochemical properties, and innovative applications of these nanocelluloses. Promising technical applications including gels/foams, thickeners/stabilizers as well as reinforcing agents have been proposed and research from last five years indicates new potential for groundbreaking innovations in the areas of cosmetic products, wound dressings, drug carriers, medical implants, tissue engineering, food and composites. The current state of worldwide commercialization and the challenge of reducing nanocellulose production costs are also discussed.

“…Caprylyl chloride (with the mass ratio of BC 30:1) was added dropwise into the system. After 7 h, the solid product of the system was washed with ethyl alcohol and deionized water to neutralize the product and dried in an air-oven for 12 h, and CO was obtained [30]. Under this condition, the substituting degree of CO was 2.32 [27].…”

“…Recently, our research group has reported the non-isothermal crystallization of the iPP/BC composites. Results show that the non-isothermal crystallization rates ascend in the order; the compatibility of iPP/BC composites and the cooling rate have great influence on the non-isothermal crystallization behavior of iPP/BC composites [30].…”

Bacterial cellulose (BC) is a new kind of cellulose with great potential in enhancing preparation of isotactic Polypropylene (iPP) composites, which have been found with excellent performance. However, the interface compatibility between BC and iPP is poor. In this study, iPP/BC composites were prepared by solution mixing. Esterification modified BC (CO) and Maleic anhydride grafted polypropylene (MAPP) added as a compatibilizer was both used to improve the interfacial compatibility of the iPP/BC composites. The rheology and isothermal crystallization behavior of the composites was tested and discussed. The result shows that the complex viscosity and storage modulus of the composite significantly increase in the rule iPP, iPP/BC2, iPP/CO2, and M-iPP/BC3, which indicates that the compatibility of the composite increases as this rule. According to the isothermal crystallization kinetics result, the crystal growth mode of iPP was not affected by the addition of BC and the interfacial compatibility. The spherulite growth rate of the iPP/BC composite increases with increasing crystallization temperature. Especially, the value decreases as the same rule with the complex viscosity and storage modulus of the composite at the same isothermal crystallization temperature. These results suggest that the interface compatibility of iPP/BC composites is greatly improved and the interface compatibility of the M-iPP/BC3 is better than the iPP/CO2.

So far, maleic anhydride or glycidyl methacrylate as compatibilizer was used to graft PP which is general method to improve the interfacial adhesion between fibers and matrix . Sakai group found that lignin derivatives could improve the compatibility of PP and carbon fiber effectively.…”

Polypropylene (PP) is widely used in the automotive industry due to its excellent mechanical properties, good formability, and low cost. Herein, the spray‐free PP composites reinforced by graphene oxide@short glass fiber (GO@SGF) were fabricated by extrusion compounding and injection molding. Aluminum powder was used as spray‐free filling materials. The microstructure and composition of SGF and GO@SGF are investigated using scanning electron microscopy and X‐ray photoelectron spectrometer. The effect of GO@SGF on the mechanical properties of spray‐free PP composites was studied. The results showed that both tensile strength and modulus were effectively improved by incorporation of GO@SGF. This mainly attributed to the improved interfacial bonding between the reinforcements and matrix.
