“…FTIR spectroscopic analysis was carried out to examine the intermolecular hydrogen bonding of the α‐cellulose and ODLA‐grafted α‐cellulose and different composites because it is the most frequently used technique for studying intermolecular and intramolecular interactions in polymers and composites . Figure shows the FTIR spectra of the α‐cellulose, ODLA‐grafted α‐cellulose, LGC‐20 composite, and PLLA.…”

α‐Cellulose extracted from jute fiber was grafted with oligo( d‐lactic acid) (ODLA) via a graft polycondensation reaction in the presence of para‐toluene sulfonic acid and potassium persulfate in toluene at 130 °C for 9 h under 380 mmHg. ODLA was synthesized by the ring‐opening polymerization of d‐lactides in the presence of stannous octoate (0.03 wt % lactide) and d‐lactic acid at 140 °C for 10 h. Composites of poly( l‐lactic acid) (PLLA) with the ODLA‐grafted α‐cellulose were prepared by the solution‐mixing and film‐casting methods. The grafting of ODLA onto α‐cellulose was confirmed by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The analysis of the composites was performed with FTIR spectroscopy, SEM, wide‐angle X‐ray diffraction, and thermogravimetric analysis. The distribution of the grafted α‐cellulose in the composites was uniform and showed better compatibility with PLLA through intermolecular hydrogen bonding. Only homocrystalline structures of PLLA were present in the composites, and the thermal stability increased with increasing percentage of grafted α‐cellulose. © 2019 Wiley Periodicals, Inc. J. Appl.

“…Specific MW effects were also reported recently, indicating that a molecular level interaction between the MW and cellulose (via the primary alcohol groups, i.e., -CH 2 OH groups) is responsible for transferring the MW energy to their surrounding molecular structure to initiate the cleavage of polysaccharide chains [13]. The cellulose samples used in the hydrolysis research are largely crystalline [18,21] with amorphous cellulose found to be unstable in aqueous systems forming partially crystalline cellulose II [22]. Therefore, cellulose is very likely to be MW-transparent as the polysaccharide chains are constrained in the crystal lattice and not able to respond to the MW irradiation microscopically.…”

Microwave (MW) assisted catalyst-free hydrolysis of fibrous cellulose (FC, cellulolysis) at 200°C promoted a cellulose conversion of ca. 37.2% and quantitative production of valuable C5/C6 sugars (e.g., glucose) and the according platform biochemicals (e.g., 5-hydroxymethylfurfural), corresponding to an overall selectivity of 96.5%. Conversely, conventional hydrothermal cellulolysis under similar conditions was not effective, even after 24 h, carbonising the FC. Based on the systematic study of MW-assisted cellulolysis, the specific interaction between water molecules and macroscopic FC under the MW irradiation was proposed, accounting for the interpretation of the experimental observation. The kinetic energy of water molecules under the MW irradiation facilitated the C-C (in the non-hindered surface -CH 2 OH groups) and C-O-C bond breaking (inside the cellulose cavities) in FC, producing primary cellulolysis products of xylose, glucose and cellobiose.

“…The 30% untreated DSF biodegraded faster in the soil as compared to treated DSF biocomposites, with the weight loss of 5.6% at day-80. The untreated DSF contained a higher amount of amorphous materials such as lignin and hemicellulose, the disordered nature of amorphous region made it more susceptible for the microbial attack [10,11]. Moreover, the alkali pre-treatment step increased the interfacial adhesion between the fiber and the matrix [12], which gave resistance to the treated DSF composites neither hydrolysis nor microbial attack.…”

In this work, the alkali (NaOH) treated and untreated durian skin fibers (DSF) were added into polylactic acid (PLA) to form biocomposites. The PLA/DSF biocomposite preparation was performed via melt blending method (180°C, 50 rpm and 10 mins retention time) at different loadings of DSF, i.e., 15, 25, 30 and 40 wt%, followed by compression molding to form thin sheet. The experimental investigation was carried out to study the weight loss of the PLA/DSF subjected to soil burial for 80 days and hygrothermal test for 14 days. Results showed that the incorporation of DSF can accelerate the weight loss of PLA, higher weight loss was observed at higher fiber content in both soil burial and hygrothermal test. Scanning electron microscope (SEM) micrographs showed the presence of crack line and voids, signs of degradation for soil buried sample.
