“…In the other hand, increased nanofibers contents had a tendency to increase tensile strength values. Cellulose nanofibers have demonstrated to improve the mechanical performance of others starch‐based films and this improvement can be explained by: the small size of the fibers, which provides homogeneous distribution and good interaction with the polymer matrix, forming a strong hydrogen bonded percolation cellulose nanofibers network with reinforcement effect; and by the intrinsic high stiffness properties of crystalline cellulose …”

In this study, the use of cellulose nanofibers from ramie, a plant species with important characteristics of reinforcement, was investigated in the production of bio-based polymer films. A central composite rotatable design was applied to produce the films, analyze the effects of cassava starch, glycerol, and nanofibers content on their properties, obtain mathematical models, response surface plots, and determine an optimum composition. The films produced were characterized by mechanical properties, water vapor permeability (WVP), solubility, and opacity. Microstructure and thermal behavior were also evaluated. The ramie nanofibers content had a positive effect on mechanical and barrier properties, as it increased tensile strength by 207.9%, and decreased WVP and solubility by 52.9 and 72.9%, respectively. Furthermore, the obtained films exhibited homogeneous and cohesive structures, which encourages the use of ramie nanofibers as a reinforcement material in the production of green plastics.

Poly(hydroxybutyrate) (PHB) has become an attractive biomaterial in research and development for past few years. It is natural bio‐based aliphatic polyester produced by many types of bacteria. Due to its biodegradable, biocompatible, and eco‐friendly nature, PHB can be used in line with bioactive species. However, high production cost, thermal instability, and poor mechanical properties limit its desirable applications. So there is need to incorporate PHB with other materials or biopolymers for the development of some novel PHB based biocomposites for value addition. Many attempts have been employed to incorporate PHB with other biomaterials (or biopolymers) to develop sustainable biocomposites. In this review, some recent developments in the synthesis of PHB based biocomposites and their biomedical, packaging and tissue engineering applications have been focused. The development of biodegradable PHB based biocomposites with improved mechanical properties could be used to overcome its native limitations hence to open new possibilities for industrial applications.

“…Cellulose nanofibers can be isolated from various lignocellulose sources, including OPEFBs. Nanocellulose from OPEFB has been successfully isolated by chemical treatment using sulfuric acid hydrolysis and mechanical treatment using a combination of ultrafine grinding and ultrasonication (Fahma, Iwamoto, Hori, Iwata, & Takemura, 2010;Fahma, Sugiarto, Sunarti, Indriyani, & Lisdayana, 2017).…”

Fibres with nanocellulose isolated from oil palm empty fruit bunches (OPEFBs) were produced. Nanocellulose and PVA-nanocellulose fibres were prepared by wet spinning in an acetone coagulation bath without drawing. The addition of nanocellulose was varied from 10% to 30%, to reveal the beneficial effects of nanocellulose content on the properties of produced spun-fibres. Higher concentration of nanocellulose increased the stiffness of spun-fibres. PVA and PVA-bacterial cellulose fibres were also produced as a control and for comparison, respectively. The nanocellulose fibre formed a compact structure, while PVA fibres had hollow structures. The effect of the produced spun-fibres on the biocompatibility of calf pulmonary artery endothelial cells was assayed by an MTT test. Based on the MTT assay the addition of nanocellulose increased the percentage of cell viability of the obtained spunfibres slightly. These results point towards the use of sustainable sources of nanocellulose as a beneficial and biocompatible fibre material. ARTICLE HISTORY
