“…The incorporation of nanocellulose into PVOH matrix interrupted the original interaction between rigid and soft segments, which led to a higher microphase separation in the polymer matrix and, hence, a decrease in T g . Nevertheless, a few authors have observed an improvement in the T g of the host polymer when adding nanocellulose from sugar palm, sugar beet, microcrystalline cellulose, sugarcane bagasse, and empty fruit bunch . A great enhancement in T g was reported by Ilyas et al .…”

“…It could be attributed to the restriction imposed by the intermolecular bonding between the filler and the matrix, which limited the flexibility and mobility of starch chains and led to an improvement in T g . Strong hydrogen bonding between the filler and the polymer matrices also lead to an improvement in T g …”

Nanocellulose has received increasing attention in science and industry in recent years as a nanoscale material for the reinforcement of polymer matrix composites due to its superior mechanical properties, renewability, and biodegradability. New nanocellulose sources, modifications, and treatments are under development to reduce the high energy required during production and to create a more suitable industrial-scale production process. Thus, this paper reviews plant-based nanocellulose composites and their properties, with a focus on their thermal-related characteristics. The purpose of this review is to establish for readers the impact of the incorporation of nanocellulose on the thermal and dynamic mechanical properties of nanocellulose composites. Understanding of the thermal properties is important for researchers to assess the suitability of the nanocomposites for a variety of applications in response to new and evolving societal requirements.The first NFC was produced from wood by using high-pressure homogenization without any pretreatment. 11,12 However, this method is a very energy-intensive process. Therefore, chemical treatments such as 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation combined with mechanical and chemical

Starch-corncob cellulose-cassia oil (SCC) composite films are fabricated by a solution casting technique, using corn starch as substrate, corncob cellulose fibers as the reinforcing material, and cassia oil added as the bacteriostatic agent. The morphology, transmittance, thermal properties, permeability, and mechanical properties of the SCC composite films are studied. The SCC composite film with 2% w/w corncob cellulose and 0.2% v/w cassia oil show good properties. The surface of the SCC composite film is smooth, and the components are evenly mixed as shown by scanning electron microscopy images. Fourier transform infrared spectroscopic analysis also show that both cassia oil and corncob cellulose molecules successfully enter the starch matrix, and a stable starch-corncob cellulose cassia oil composite film is formed. Thermogravimetric analysis of the SCC composite film shows that the film has good thermal stability and good heat resistance. In the SCC composite film with 2% w/w corncob cellulose, tensile strength decreases the content of cassia oil increases, but elongation at break shows the trend of increasing initially and then decreasing. The SCC composite films have good mechanical properties and can keep fruit fresh, indicating that the composite film can be used as a good food packing material.

Bionanocomposite films were fabricated using starch as a matrix, pre-oxidised sucrose as a crosslinker and cellulose nanofibres as reinforcement filler. The spectroscopic (FTIR) and microscopic (SEM) techniques were used to identify the chemical changes associated with the crosslinking, and to characterize the morphological structure of the films. The crosslinking density evaluated by Flory-Rehnar equation. There is a decrease in diff usivity, permittivity and swelling properties of the films after crosslinking. Reduction of water vapour (from 0.074 to 0.038 g min−1 m-2) and oxygen (from 29.44 to 10.27 cm 3 m-2 d −1) transmission rates for film prepared with 3 wt.% of OS and 5 wt.% of CNFs was observed. The water transport through the films was found to follow Fickian behaviour. The antibacterial properties of films against four diff erent food pathogens were evaluated. Films represent high potential alternative to existing ones.
