Photonic crystal elastomers that can change colour upon stretching or compression have potential applications in mechanical sensors and optical coatings. However, facile synthetic strategies are required for these materials to be made on a commercially viable scale. To address this issue, we report photoinitiated polymerisation method prepare stretchable chiral nematic cellulose nanocrystal (CN...

Abstract The Martini coarse-grained force field is one of the most popular models for molecular dynamics (MD) modelling in biology, chemistry, and material science. Recently, a new version, 3, had been reported with improved interaction balance many bead types. Here, we present cellulose nanocrystal (CNC) model based on 3. calculated CNC structures, lattice parameters, mechanical properties rep...

In the present study, polyamide (PA) was successfully reinforced with cellulose nanocrystal (CNC) prepared from date palm leaves using two different techniques, electrospinning and solution casting method, a comparative study of these systems performed. The morphological, thermal, wetting, mechanical properties nanocomposites were analyzed for CNC content between 0 5 wt%. Morphological analyses...

Cellulose is the most venerable and essential natural polymer on planet drawing greater attention in form of nanocellulose, considered an innovative influential material biomedical field. Because its exceptional physicochemical characteristics, biodegradability, biocompatibility, high mechanical strength, nanocellulose attracts considerable scientific attention. Plants, algae, microorganisms ar...

The mechanical properties of cellulose nanocrystal (CNC) films critically depend on many microstructural parameters such as fiber length distribution (FLD), orientation (FOD), and the strength interactions between fibers. In this paper, we use our coarse-grained molecular model CNC to study effect attractions CNCs neat CNCs. misalignment a 2D staggered structure with respect loading direction w...

As a significant part of municipal solid waste (MSW), waste cardboard (CB) is a sustainable, inexpensive, and rich source of cellulose. Previous studies of polyolefin/CB composites have reported modest enhancement to major reduction in modulus and major reduction in elongation at break values relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and polypropylene (PP)...

Poly (vinyl pyrrolidone) (PVP)/cellulose nanocrystal (CNC)/silver nanoparticle composite fibers were prepared via electrospinning using N,N'-dimethylformamide (DMF) as a solvent. Rheology, morphology, thermal properties, mechanical properties, and antimicrobial activity of nanocomposites were characterized as a function of material composition. The PVP/CNC/Ag electrospun suspensions exhibited h...

Evaporation-induced-self-assembly is widely used to produce chiral cellulose nanocrystal (CNC) free-standing films reflecting left-handed polarized light. Research on supported CNC rather scarce. The reflection and/or transmission of unpolarized light are the most common optical techniques characterize selective whereas use quantify properties limited. Here, fabrication glass substrates by a sh...

Nanocellulose, a unique and promising nanosized cellulose fibers extracted from renewable biomass, has gained much attention both the scientific industrial communities due to abundant resources, good mechanical properties, distinct surface chemistry, biological properties. Thus, nanocellulose is appealing biomaterial for exciting applications, including super absorbent materials, electronic com...

Numerous biodegradable hydrogels for cartilage regeneration have been widely used in the field of tissue engineering. However, to non-invasively monitor hydrogel degradation and efficiently evaluate cartilage restoration in situ is still challenging. Methods: A ultrasmall superparamagnetic iron oxide (USPIO)-labeled cellulose nanocrystal (CNC)/silk fibroin (SF)-blended hydrogel system was devel...
