Abstract Inhibition of radial growth and spore germination Aspergillus niger in media with added chitosan were detected. The highest inhibition (73%) was determined at 24 h 3 g · L −1 chitosan, the percent 40% after 13 inoculation. Further, CC 50 , that is, concentration which is inhibited by 50%, estimated probit analysis (3.5 ). activation energies, E A an Arrhenius model control amended media, obtaining 35.6 36.6 kcal mol respectively. These values same order magnitude because as...
Homogeneous and thin porous membranes composed of oriented fibers were obtained from wheat gluten (WG) using the electrospinning technique. SEM micrographs showed an asymmetric structure some porosity, which, in addition to a small thickness 40 mm, are desirable characteristics for membranes’ potential application release systems. The loaded with urea obtain pastilles. FT-IR DSC studies confirmed existence interactions via hydrogen bonding between WG proteins. pastilles studied as...
Abstract Chitosan is a natural polymer with both antimicrobial activity and nanofiber‐forming capability. The electrospinning technique allows the production of chitosan nanofibers but still faces several problems such as small number suitable solvents for process large factors affecting quality nanofibers, among others. properties have been little studied; therefore, most probable mechanism action effect conformation or arrangement molecules in remain unknown. presence residual solvent...
Abstract This work explores new pathways to obtain CdS semiconductor films capable of covering almost any kind solid substrate. Water‐soluble polyvinylpyrrolidone (PVP) was used prepare fibers PVP/CdCl 2 and PVP/CdS composite materials, which are later dissolved support‐free on an aqueous surface, can be collected thereafter with the desired The were produced by electrospinning, subsequent treatments for formation followed two distinct routs: (1) a direct reaction between electrospun 0.10 M...
Electrospun poly (methyl methacrylate) (PMMA) microfibers were combined with ZnO to enhance the photodegradation of dye molecules. The microstructural characteristic fibrous material used for decomposition methylene blue (MB) present in aqueous solutions under dark and sunlight irradiation was studied using UV-Vis absorption photoluminescence spectroscopy. PMMA membrane embedded particles low temperature heat treatment providing better handling changing its morphology. average diameter...
Electrospun nanofibers from gelatin (G), chitosan (CS), and chitosan-polyvinyl alcohol (CS-PVA) were developed by electrospinning process. Mechanical properties determined the tensile test, elastic modulus values of G (15.418-34.34 MPa) CS-PVA (17.44-126.427 MPa). The morphological characterization SEM revealed that systems with 15% 6% showed homogeneity. Structural FTIR indicated an interaction among some functional groups component. Thermal analysis DSC TGA degradation temperatures for...
This study addresses the fabrication of extruded films using poly(lactic acid) (PLA) and chitosan, with without maleic anhydride as a compatibilizing agent, for potential applications in disposable food packaging. These underwent controlled conditions UV irradiation, water condensation, temperature variations an accelerated weathering chamber. The investigation analyzed effect different exposure periods on structural, morphological, mechanical, thermal properties films. It was observed that...
In this article, we present a study of the influence temperature and humidity on electric conductivity polyaniline polypyrrole thin films doped with iodine synthesized by plasma (PAn/I PPy/I, respectively). The polymers presented characteristic ohmic conduction mechanism via electrons; however, was much lower than that obtained traditional chemical oxidation. We submitted to heating–cooling cycles dependence conductivity. During heating stage cycles, PPy/I showed strong content. However,...
ABSTRACT The electrical, mechanical, and piezoresistive properties of ternary composites based on elastomeric polydimethylsiloxane (PDMS), carbon nanotubes (CNTs), polyaniline (PANI) were studied compared with those binary PDMS–CNT composites. presence PANI affected the percolating network CNTs. At lower concentrations (2.5 5%), conductive CNTs was constructively modified; this led to an enhancement in conductivity sample containing 2% A higher content (7.5%) hindered flow main charge...
Abstract Thermosensitive polymers based on poly( N ‐isopropylacrylamide) (pNIPAM) have been widely evaluated in a variety of biomedical applications due to their particular thermal behavior aqueous solutions. Despite this, few works focused the complementary analysis transitions pNIPAM linear and crosslinked form. In this work, ‐isopropylacrylamide‐co‐acrylic acid) p(NIPAM‐co‐AA) copolymers were synthesized at similar NIPAM/AA feed composition thermosensitive was studied by turbidimetric...
