Abstract Freeze dried nanofibrils were acetylated in a heterogeneous system with acetic anhydride, pyridine, and dimethylformamide the obtained cellulose (CNF ac ) combined poly(lactic acid) (PLA) to composite. CNF its partially hydrophobic surface showed good compatibility PLA resulting composite films improved properties. Tensile strength (TS), modulus of elasticity (MOE), elongation at break (EB) PLA/CNF increased significantly when 2–5% was added matrix, while addition 10% higher amounts...
The curing kinetics of foam prepared from the tannin spruce tree bark was investigated using differential scanning calorimetry (DSC) and advanced isoconversional method. An analysis formulations with differing amounts components (furfuryl alcohol, glycerol, tannin, a catalyst) showed that delayed increasing proportions glycerol or tannins. optimum amount catalyst constituent also found during study. system accelerated temperatures. Finally, method, based on model-free kinetic algorithm...
This work investigates the feasibility of using recycled polypropylene (rPP), cellulose (CF) and newsprint (NP) fibres in polyolefin reinforced composites. Recycled PP filled with 40 wt.% (rPP/CF) or (rPP/NP), addition impact modifier (IM) compatibilizing agent (CA), have been prepared extrusion melting injection moulding. Melting crystallization behaviour plain matrix composites were measured by differential scanning calorimetry (DSC). Morphological mechanical properties also studied...
Hydrogels are classified as a three-dimensional network system, capable of retaining large amounts water while preserving their shape and dimensional stability.Due to natural origin biocompatibility with human tissue, cellulose nanofibrils often considered be promising candidates for bioactive hydrogels preparation.For such applications, responsiveness under different types mechanical load, including multiple cyclic compressions, is crucial importance.In the present study, nanofibril-based...
