Abstract This work investigates the resistance against marine corrosion of an epoxy‐based coating modified by the addition of electrochemically produced and oxidized poly(3,4‐ethylenedioxythiophene) (PEDOT). For this purpose, electrodeposition of PEDOT was performed on steel electrodes by electrochemical polymerizatio…
Abstract In this study, melamine cyanurate (MCA)/melamine phosphate (MP) composite flame retardants were synthesized in the solution of phosphoric acid/polyamide 6 (PA6). Phosphoric acid acted as the solvent of PA6, catalyst of melamine‐cyanurate self‐assembly reaction and reactant of melamine‐phosphoric acid reaction…
Abstract Textile biocomposites were prepared by reinforcing natural rubber with woven sisal fabric. Sisal fabric was subjected to various chemical modifications like mercerization, silanization, and thermal treatment. The moisture uptake of the textile composites was found to depend upon fiber content as well as archi…
Thanks a bundle! A strong photoresponse for macroscopic bundles containing thousands of aligned carbon nanotubes (suspended between two electrodes, see figure) upon illumination is observed at wavelengths ranging from the visible to the far-infrared. At a relatively small applied bias, the current flow in the nanotube…
Potassium neodymium molybdenum oxide, KNd(MoO 4 ) 2, has been synthesized by the solid-state method. The structure and microstructure have been studied by X-ray powder diffraction and transmission electron microscopy (TEM). TEM revealed that the KNd(MoO 4 ) 2 structure is incommensurately modulated. The scheelite-like…
Abstract Modification of a Soxhlet apparatus widely used for extraction is suggested. This modification is aimed at overcoming the main disadvantage of the Soxhlet apparatus for extraction, that the extraction takes place at around room temperature. The modified apparatus allows extraction to be performed with boiling…
Abstract Assembled structures of calcium carbonate (CaCO 3 ) nanocrystals have been examined for polymer/CaCO 3 thin‐film composites synthesized through a self‐organization process inspired by biomineralization. For the crystallization of CaCO 3 , a thin‐film matrix of chitosan has been used as a polymeric substrate.…
The triple-decker complex [Yb 3 L 3 (OAc) 2 Cl](H 2 O) 3 (CH 3 OH) 1.5 (CH 3 CN) 0.5 ( 1 ) is formed from the reaction of H 2 L, YbCl 3 ·6H 2 O, and Zn(OAc) 2 ·2H 2 O in 25% yield (H 2 L = N, N ‘-bis(5-bromo-3-methoxysalicylidene)phenylene-1,2-diamine). The single-crystal X-ray structure of 1 revealed the presence of…
Abstract The viscose rayon containing cyclotriphosphazene were prepared by the method of blending spinning. The combustibility and thermal stability of the fire‐retardant viscose rayon were evaluated by 45 ° slope burning method, limit oxygen index (LOI), differential scanning calorimetry, thermogravimetry analysis. T…
Abstract The surfaces of polyester (PET) fabrics and foils were modified by low‐pressure RF plasmas with air, CO 2 , water vapor as well as Ar/O 2 and He/O 2 mixtures. To increase the wettability of the fabrics, the plasma processing parameters were optimized by means of a suction test with water. It was found that lo…
Abstract Oleoyl‐chitosans (O‐chitosans), with three degrees of substitution (DS), were synthesized by reacting chitosan with oleoyl chloride. The chemical structures of these polymers were characterized by 1 H NMR and FTIR. The results suggested the formation of an amide linkage between amino groups of chitosan and ca…
Abstract The goal of this work was to prepare exfoliated poly(lactic acid) (PLA)/layered‐silicate nanocomposites with maleic anhydride grafted poly(lactic acid) (PLA–MA) as a compatibilizer. Two different layered silicates were used in the study: bentonite and hectorite. The nanocomposites were prepared by the incorpo…
Abstract Differential scanning calorimeter (DSC) and polarized optical microscopy (POM) have been used to investigate the isothermal and nonisothermal crystallization behavior of poly(ε‐caprolactone) (PCL)/multi‐walled carbon nanotube (MWNT) composites. PCL/MWNT composites have been prepared by mixing the PCL polymer…
Abstract Composites with good mechanical properties were prepared from chemically modified soy oils and biofibers without additional petroleum‐based polymers. These composites were prepared from maleic anhydride and epoxide functionalized soybean oils that were cured in the presence of various biofibers (e.g., kenaf,…
Abstract Nylon 11 (PA11)/clay nanocomposites have been prepared by melt‐blending, followed by melt‐extrusion through a capillary. Transmission electron microscopy shows that the exfoliated clay morphology is dominant for low nanofiller content, while the intercalated one is prevailing for high filler loading. Melt rhe…
Abstract An approach of using slowly crystallizing polymers to form single‐polymer composites (SPCs) was investigated. The method was demonstrated using poly(ethylene terephthalate) (PET) as a model system, with which two distinct physical forms, namely, amorphous PET films and highly crystalline PET fibers can be rea…
Abstract Supramolecular nanotube hosts with precisely controlled inner or outer diameters have been synthesized by self‐assembly of unsymmetrical bolaamphiphilic monomers or glucopyranosylamide lipids, respectively. Time‐resolved fluorescent measurement using 8‐anilinonaphthalene‐1‐sulfonate (ANS) as a probe revealed…
We have developed facile, versatile prepolymerization and postpolymerization functionalization approaches to prepare well-defined fluorescent conjugated fluorene-based glycopolymers (polymers A and B) through thioether formation. Well-defined glucose-carrying monomer (5) and conjugated polymer (polymer 2) were prepare…
Abstract The spin‐crossover properties of lipophilic, supramolecular Fe(II) complexes bridged by 4‐(3‐dodecyloxy)propyl‐1,2,4‐triazole [Fe(II)( 1 ) 3 Cl 2 ] were investigated in chloroform and cast films. A purple low‐spin (LS) complex in a powdery form was transformed into pale yellow high‐spin (HS) polymers by disso…
Abstract Recycled poly(ethylene terephthalate) from waste bottles (hereafter, rPET) was used as an reinforcing material for isotactic polypropylene (iPP) based on the concept of in situ microfibrillar‐reinforced composites (iMFCs). Microfibers of rPET were successfully generated during melt‐extrusion and subsequent dr…
