We investigated the potential of an electron-beam post-treatment to tailor properties 70/30 and 80/20 wt. extruded starch-lignin films. The effect a 400 kGy radiation on films differing essentially by kind lignins incorporated (lignosulfonates/alkali lignins) was assessed both at macroscopic molecular levels. Changes in polymer structure were studied IR spectroscopy, thioacidolysis as well model compound experiments. Electron beam-irradiation kGy, rather high dose for processing natural...
Diabetic foot ulcers (DFU) are among the most common complications in diabetic patients and affect 6.8% of people worldwide. Challenges management this disease decreased blood diffusion, sclerotic tissues, infection, antibiotic resistance. Hydrogels now being used as a new treatment option since they can be for drug delivery to improve wound healing. This project aims combine properties hydrogels based on chitosan (CHT) polymer β cyclodextrin (PCD) local cinnamaldehyde (CN) ulcers. work...
The coating of a nonwoven textile by polyelectrolyte multilayer film (PEM) issued from cationic and anionic β-cyclodextrin (βCD) polyelectrolytes according to the layer-by-layer (LbL) technique was successfully attempted. tert-butyl benzoic acid (TBBA) used as drug model evaluate loading capacity sustained release properties this PEM system. build-up assembly monitored in situ optical waveguide lightmode spectroscopy (OWLS) on one hand, assessed gravimetry other hand when applied onto...
We describe the application of LCST a naphthalene-functionalised polyNIPAM derivative as convenient, tuneable and reversible method to disrupt complex formation with CBPQT(4+) in water.
This work focuses on the manufacture of core-sheath nanofibers (NFs) based chitosan (CHT) as sheath and cyclodextrin polymer (PCD) core loaded with triclosan (TCL). In parallel, monolithic NFs consisting blended CHT-PCD TCL were prepared. Nanofibers characterized by scanning electron microscopy (SEM), transmission (TEM), Fourier Transform Infrared spectroscopy (FTIR). SEM displayed morphology structure nanowebs, while TEM evidenced prepared coaxial electrospinning. The diameters thicknesses...
Injectable pre-formed physical hydrogels provide many advantages for biomedical applications. Polyelectrolyte complexes (PEC) formed between cationic chitosan (CHT) and anionic polymers of cyclodextrin (PCD) render a hydrogel great interest. Given the difference water-soluble (PCDs) water-insoluble PCD (PCDi) in extension polymerization, present study aims to explore their impact on formation properties CHT/PCD obtained from variable ratios PCDi PCDs formulation. Hydrogels CHT/PCDi/PCDs at...
A series of poly(N-isopropylacrylamide)s (poly(NIPAM)s) have been synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization from a functionalized agent (CTA) bearing either dialkoxynaphthalene or dialkoxyphenylene moieties. After demonstrating the controlled character RAFT in presence these CTAs, well-defined poly(NIPAM)s with low PDIs and similar molecular weights were selected subjected to lower critical solution temperature (LCST) measurements using UV-vis...
Environmental regulation and depletion of fossil resources are boosting the search for new polymeric materials produced from biomass. Here, synthesis a diester bearing pendant lactam unit methyl levulinate aspartic acid is reported. The palladium-catalyzed reductive amination/cyclization sequence was carefully optimized to afford diacid with high yield (>95 %). In second step, compound esterified give corresponding diester. latter monomer copolymerized α-ω linear diols, yielding polyesters...
