Chitosan without hydrophobic modification is not a good emulsifier itself. However, it has pH-tunable sol-gel transition due to free amino groups along its backbone. In the present work, simple reversible Pickering emulsion system based on of chitosan was developed. At pH > 6.0, as adjusted by NaOH, insoluble in water. nanoparticles or micrometer-sized floccular precipitates were formed situ. These aggregates could adsorb at interface oil and water stabilize o/w emulsions, so-called...
Abstract Environment‐friendly carboxymethyl cellulose (CMC) hydrogel beads were successfully prepared using epichlorohydrin (ECH) as a crosslinking agent in the suspension of fluid wax. There was an ether linkage formed between ECH and CMC, which identified from bands FTIR spectra hydrogel. The with diameters about 4 mm apparently spherical fully transparent. X‐ray diffraction (XRD) indicated that adsorption metal ion onto oxygen atom carboxyl group led to change crystallinity patterns...
The cellulose fiber was extracted from the abandoned crop sugarcane bagasse (SCB) by means of chemical treatment methods. Poly(lactic acid) (PLA) bio‐based composites with SCB were prepared through fused deposition modeling (FDM) 3D‐printing technology, and morphologies, mechanical properties, crystallization thermal stability 3D‐printed investigated. Compared neat PLA, incorporation into PLA reduces tensile strength flexural samples but increases modulus. difference in performance bending...
Abstract Lignocellulosic biomass is a promising feedstock for sustainable production of non‐food building‐block sugars. This bioconversion process preferentially carried out through the whole slurry enzymatic saccharification pre‐treated lignocellulosic substrates. However, dissolved lignin, residual and lignin‐derived phenolic molecules in can all trigger decrease activity stability cellulases, as well unfavorable enzyme recyclability. The hydrolyzing efficiencies be considerably hindered...
Polyurethane (PU) is a synthetic material available for researchers to be designed in terms of their demands. This study prepared novel polyurethane thermoplastic elastomer (PUTE) as an asphalt modifier through the reasonable selection raw materials and formula. The results Fourier transform infrared spectroscopy (FTIR) test confirm chemical reaction between ─ NCO groups PUTE prepolymer OH most polar molecules (asphaltenic regions). Effects modifications (1%, 3%, 5%, 7%, 9%, 11%, 13%, 15% by...
Abstract The shape of 3D printed products can be transformed over time, achieving 4D printing. In this work, poly(lactic acid) (PLA)/poly(ε‐caprolactone) (PCL) blends are fabricated via fused deposition modeling (FDM). thermoresponsive memory effects (SMEs) investigated by stress‐controlled dynamic mechanical analysis in tension mode. SME mechanism is clarified detail, along with the crystallization and melting behaviors, properties, morphologies PLA/PCL blends. It confirmed that...
The corrosion inhibition performance of an imidazolium-based ionic liquid (IL), 1-butyl-3-methylimidazolium thiocyanate (BMIm), was studied on AA 6061 alloy in 1 M HCl solution at 303 K, 333 and 363 K by gravimetric tests, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) analysis. Scanning electron microscopy with energy dispersive X-ray (SEM-EDX) photoelectron (XPS) were used to detect the surface morphologies chemical composition films. results indicate that this...
Chitosan scaffolds with hierarchical macroporous structures for recyclable adsorption of Cu(II) ions are prepared by templating from Pickering high internal phase emulsions (HIPEs) the first time. The liquid paraffin-in-water HIPEs stabilized chitosan nanoparticles (CNPs). fraction can be up to 90.0%; meanwhile, concentration only needs 1.0 wt%. were obtained crosslinking dispersed CNPs, followed removing phase. resulting scaffold exhibits average pore size around 15 μm and interconnecting...
Abstract Bio‐scaffolds designed to mimic endogenous niches have been used extensively in stem cell therapy and tissue regeneration. However, limited entry of nutrients cells inside the scaffold can lead poor survival proliferation, implantation require an invasive surgical approach. Here, a noninvasive method using injectable 3D porous micro‐scaffolds with bio‐engine is developed for transplantation A liquid nitrogen flash‐frozen immediately smashed prepare nanocarriers‐alginate composite...
For flexible electronics, the substrates play key roles in ensuring their performance. However, most suffer from weak bonding with conductive ink and need additional aids. Here, inspired by Ag-S bond theory, a novel cellulose nanopaper substrate is presented to improve strength Ag nanoparticle through facile printing method.
