“…For the unmodified biocomposites, a two‐step decomposition process is observed, as shown in Fig. : an initial decomposition at approximately 250°C and further decomposition at approximately 450°C . The initial decomposition temperature decreased with the addition of PEG and TBC, which can be explained by the improved mobility of the WF/PLA molecular segment due to the addition of low‐molecular‐weight PEG and TBC, which act as plasticizers in the WF/PLA matrix .…”

In this work, polyethylene glycol (PEG) and tributyl citrate (TBC) are proposed to modify the properties of wood fiber (WF, 20 wt%)‐reinforced polylactide (PLA, 80 wt%) biocomposites. The reinforcing and toughening effects of these additives were systematically investigated by comparing their mechanical, thermal and rheological properties. It was found that 5 wt% TBC improved the compatibility between WF and PLA and resulted in increased tensile strength (15%) and thermal stability (4%) of the biocomposites compared with those of unmodified biocomposites. The glass transition temperature, melting temperature, and crystallinity of TBC‐modified biocomposites were lower than those of PEG biocomposites. In addition, the storage modulus, loss modulus and complex viscosity of TBC‐modified biocomposites were effectively improved at low TBC content (5–10 wt%), whereas reduced properties were obtained when the same PEG content was added. As wettability is always a problem in biocomposites, the contact angle was not changed with TBC content (up to 20 wt%), and a linear decrease was observed with a PEG content up to 30 wt%. POLYM.

“…Compared to the pure resin of 29.4%, when the filler was 0.5 wt% unmodified CNC, the elongation at break dropped to 25.6%. This may be result from the uneven distribution and agglomeration of the unmodified CNC . When 0.1 wt% CNC‐ g ‐MA was added, the elongation at break increased slightly, reaching 34.5%.…”

Cellulose nanocrystal (CNC) has been widely added to various resin matrix forming resin‐based composites because of its mickle inherent advantages, but solving the agglomeration problem and making uniform dispersion of the CNC feasible still remain challenging. In the present work, methacrylic was grafted onto the surface of CNC via a simple esterification reaction. Successful modification of the CNC was confirmed by solid‐state 13C nuclear magnetic resonance (13C NMR) spectrum and Fourier transform infrared analysis. The modified CNC powder (CNC‐g‐MA) exhibited improved thermal stability and good dispersion in chloroform. Moreover, scanning electron microscope microtopographies confirmed that the modified CNC maintained uniformly nanoscaled dispersion in the resin matrix. The mechanical analysis results showed that CNC‐g‐MA greatly improved the mechanical properties of 3D‐printed samples with 43.5% enhancement in tensile strength compared to those only containing raw CNC. The thermal properties of samples were also improved slightly when CNC‐g‐MA was added due to superior dispersion and affinity with MA resin. Finally, this work paves the way for the feasible modification of CNC as suitable filler in resin‐based composites fabricated using 3D stereolithography technology. POLYM. ENG.

3D printing is recognized as a powerful tool to develop complex geometries for a variety of materials including nanocellulose. Herein, a one-pot synthesis of 3D printable hydrogel ink containing zeolitic imidazolate frameworks (ZIF-8) anchored on anionic 2,2,6,6-tetramethylpiperidine-1-oxylradicalmediated oxidized cellulose nanofibers (TOCNF) is presented. The synthesis approach of ZIF-8@TOCNF (CelloZIF8) hybrid inks is simple, fast (≈30 min), environmentally friendly, takes place at room temperature, and allows easy encapsulation of guest molecules such as curcumin. Shear thinning properties of the hybrid hydrogel inks facilitate the 3D printing of porous scaffolds with excellent shape fidelity. The scaffolds show pH controlled curcumin release. The synthesis route offers a general approach for metal-organic frameworks (MOF) processing and is successfully applied to other types of MOFs such as MIL-100 (Fe) and other guest molecules as methylene blue.This study may open new venues for MOFs processing and its large-scale applications.
