“…The uniform distribution and agglomeration is further substantiated by SEM and AFM analysis. Good interfacial interaction and stress transfer between MCC and polymer matrices are essential for good mechanical properties of composites . These results further confirm the presence of strong interfacial interaction and good dispersion between MCC and PVA .…”

Reinforcing poly(vinyl alcohol) (PVA) with biopolymers like microcrystalline cellulose (MCC) provides interesting route for the preparation of green composites. In this study, PVA and MCC from sago seed shell in different weight% were prepared by intense sonication followed by solution casting into glass plate. Composites were prepared by adding 1, 2 and 3 weight% of MCC, which were characterized using FTIR, ATR-FTIR, XRD, TGA, DSC, SEM, AFM, UV-Vis, and mechanical testing. Particle size distribution of used MCC was analyzed by DLS. ATR-FTIR spectra reveal the incorporation of MCC into the polymer matrix through hydrogen bonding. XRD pattern shows the decrease in relative intensity compared to PVA film and broadening of peaks at different MCC concentrations. DSC analysis reveals the variations in the glass transition temperature. In addition to lowering in melting temperature, changes in shape and area are attributed to the different degrees of crystallinity due to the existence of polymer-polymer interactions between PVA and MCC. The results obtained from ATR-FTIR, XRD and DSC substantiate each other. TGA results reveal the increased thermal stability compared to the PVA film. The SEM analysis shows the uniform distribution for lower loading, which is further supported by AFM. UV-Visible spectra reveal the good transparency of prepared films. Mechanical testing was also performed, in which 1 weight% gained tensile strength. The TGA and mechanical testing results showed that MCC as reinforcement in PVA film can improve thermal and mechanical strength. DLS measurements show that the particle size of MCC is >100 nm. POLYM.

Pineapple leaf microfibers (PALM) were used to prepare all-cellulose composites using the surface selective dissolution method. Effect of dissolution times on mechanical and physical properties of the all-cellulose composites was investigated. The structural transformation from cellulose I to cellulose II was observed when the fibers were dissolved in a mixed solution of lithium chloride (LiCl) and N,N-dimethylacetamide (DMAc). Values of 42.8 MPa and 1.2 GPa for tensile strength and Young's modulus, respectively, were obtained from the composites with 120 min dissolution time in the LiCl/DMAc solution, whereas the tensile strength and Young's modulus of the undissolved PALM mats were found to be only 1.5 MPa and 0.1 GPa, respectively. The failure mechanism of the composites was changed from the fiber pull-out to the fiber breakage when the dissolution time was longer. However, lower thermal stability and degree of crystallinity of the composites were caused by the change of the cellulose structure. The composites prepared in this work can be called as biodegradable materials, and could be the potential candidates to replace nonbiodegradable materials. POLYM. COMPOS., 39:895-903, 2018.

“…The interest in lignocellulosic materials in composite industry has increased recently due to their biodegradable nature. Hemp , jute , sisal , gongura , and ramie are widely studied as fillers in composite industry and are in great demand. They are widely used in composites for furniture, construction, packaging industries, and automobiles .…”

The aim of the work was to develop environmental friendly coir pith-based composites with a good balance of mechanical properties. Multilayered coir pith/ nylon fabric/epoxy hybrid composites were fabricated by the hand lay-up technique followed by compression molding. A set of composites of same composition having chemically treated coir pith was also prepared. Mechanical properties of composites such as tensile strength, impact strength, flexural strength, hardness, and abrasion resistance were evaluated. The hybridization with nylon fabric and the chemical treatment of coir pith enhances the mechanical properties of composites. Chemical resistance and void content of the composites were also determined and reported. A comparative evaluation is done between composites having chemically treated coir pith and untreated coir pith. Coir pith was subjected to different treatments such as sodium hydroxide treatment followed by sulfuric acid, dicumyl peroxide, sodium hypochlorite, acrylic acid, and acetic acid. POLYM. COMPOS., 37:649-657, 2016.
