“…The CS-MCC10 membrane resulted in a rise of σ by 81.01%. This is almost similar to the results discussed by Li et al (2012) 4 that showed an increase of 83.55% with the addition of 10(w/w%) MCC compared to a pure CS membrane. The CS-CMC10 membrane showed the second highest strength with a σ value of 62.22 MPa ± 4.32 MPa.…”

Polymer biocomposites have attracted a lot of attention due to the increasing requirements for biomaterials to replace conventional materials. This replacement is due to the remarkable properties of biomaterials, including their biocompatibility, biodegradability and non-toxicity. Chitosan (CS) is a renowned abundantly-available biopolymer that is furnished with such properties. However chitosan is known to be unstable in acidic conditions, and it has fairly low mechanical strength and requires further improvement for various applications. This study aims to improve the properties of chitosan by making composites of CS reinforced with carboxymethyl cellulose (CMC), microcrystalline cellulose (MCC) and halloysite nanotubes (HNTs). These composites were prepared through solvent casting method and were investigated for their mechanical, chemical and morphological properties. The mechanical testing results showed that the CS/MCC membranes had the best mechanical properties, with a tensile strength (σ) of 79.98±8.12 MPa and a Young's modulus (E) of 2.44±0.21 GPa. Scanning electron micrographs confirmed that the high mechanical strength of CS/MCC membranes is attributed to better dispersion of MCC in chitosan. Infrared spectroscopy compared the chemical interactions between the main functional groups of the matrix and fillers. A surface wettability test was performed and revealed that chitosan membranes reinforced with 10 (w/w%) of CMC had the lowest (88.45°) and chitosan membrane with 5 (w/w%) HNT and 5 (w/w%) had the highest contact angle (130.83°). Addition of both CMC and MCC led to an improvement of the mechanical properties over the pure chitosan membrane, which was attributed to a significant interaction between chitosan and cellulose through hydrogen bonding.

“…Some of these materials are based on polyesters, protein or even polysaccharides 2 . Amongst these materials, chitosan (CS) has gained a large interest in this area [3][4][5] . It is a naturally occurring polysaccharide polymer consisting of glucosamine and N-acetyl glucosamine.…”

“…In addition, research conducted by Huang et al [5] showed the tensile strength value of chitosanmicrocrystalline cellulose films, and the addition of cellulose microcrystals to chitosan films decreased the value of water vapour permeability. Other studies have shown chitosan-microcrystalline films with high tensile strength values [6][7]. In this work, modifications were made to the chitosan-microcrystal cellulose film with the addition of a new material, quercetin.…”

This study aimed to synthesize chitosan biodegradable films and cellulose microcrystals (CMC) from coconut fibres (Cocos nucifera) with quercetin as a filler. Chitosan (CS) film is mixed with cellulose microcrystals with a composition of 1% w/w, and quercetin bioflavonoids are added with various concentrations (0%;1%;3%;5%;7% w/w) by solution casting method. Adding quercetin to the chitosan-microcrystalline cellulose film is expected to add antioxidant properties. Cellulose microcrystals were isolated from the primary material of coconut fibres by delignification, bleaching which was then hydrolysis by 58% w/w sulfuric acid. Isolation results were characterized by FTIR, XRD and SEM. The results of research for the synthesis of chitosan-microcrystalline cellulose-quercetin films showed the addition of quercetin 7% resulted in tensile strength of 17.21 MPa, biodegradation rate of 1.62 mg/day, antioxidant activity of 79.95%. However, adding 7% quercetin decreases the nature of film development and water vapour permeability, with the optimum quercetin concentration for film development being 1% and water vapour permeability being 3%.
