Understanding the structure−property relationship in polymer/layered silicate nanocomposites is of fundamental importance designing materials with desired properties. To understand these relations case poly(butylene succinate) (PBS)/organically modified layered (OMLS) nanocomposites, we studied rheological properties detail, because behavior polymer/OMLS strongly influenced by their nanostructure and interfacial characteristics. For this reason, a series PBS/OMLS were prepared using simple...
New polylactide (PLA)/layered silicate nanocomposites have been prepared successfully by simple melt extrusion of PLA and organically modified montmorillonite. The d spacings both the montmorillonite intercalated were investigated wide-angle X-ray diffraction (WAXD) analysis, morphology these was examined transmission electron microscopy (TEM). Using oligo(ε-caprolactone) (o-PCL) as a compatibilizer, effect compatibilizer in focusing on two major aspects: morphological analysis mechanical...
Our ongoing research on the preparation, characterization, materials properties, and biodegradability of polylactide (PLA)/organically modified layered silicate (OMLS) nanocomposites has yielded results for PLA/organically synthetic fluorine mica (OMSFM) nanocomposites. Synthetic (SFM), with N-(coco alkyl)-N,N-[bis(2-hydroxyethyl)-N-methylammonium cation, was used as an OMLS preparation. The internal structure in nanometer range established using wide-angle X-ray diffraction (WAXD) analyses...
Abstract The academic and industrial aspects of the preparation, characterization, mechanical materials properties, crystallization behavior, melt rheology, foam processing pure polylactide (PLA) PLA/layered silicate nanocomposites are described in this feature article. Recently, these have attracted considerable interest polymer science research. PLA is linear aliphatic thermoplastic polyester made from agricultural products. Hectorite montmorillonite among most commonly used smectite‐type...
This letter describes the preparation, characterization, material properties, and biodegradability of polylactide (PLA)-layered silicate nanocomposite. Montmorillonite modified with trimethyl octadecylammonium cation was used as an organically layered (OMLS) for nanocomposite preparation. WAXD TEM analyses respectively confirmed that layers montmorillonite were intercalated nicely distributed in PLA-matrix. The properties neat PLA improved remarkably after nancomposite corresponding studied...
An intercalated polylactide (PLA)/layered silicate nanocomposite was prepared by simple melt extrusion of PLA and organically modified montmorillonite. The detailed crystallization kinetics morphology neat before after preparation were studied using polarized optical microscopy, light scattering, differential scanning calorimetric, wide-angle X-ray diffraction analyses. overall rate spherulitic texture pure strongly influenced in the presence montmorillonite particles.
The amylose component of starch can form complexes known as V-amylose with amphiphilic or hydrophobic ligands. are single, left-handed helices that arranged crystalline and amorphous lamellae, which may distinct nano- micron-scale structures. has potential a biomaterial for nanoencapsulation sensitive bioactive flavor ingredients, modification rheological behavior starch-containing products, reduction retrogradation, postprandial hyperglycaemia in diabetics. Various aspects structure,...
Polylactide and poly(butylene succinate-co-adipate) (PLA/PBSA) were melt-blended in the presence of triphenyl phosphite (TPP). An increase torque during melt mixing was used to monitor changes viscosity as compatibilization blends occurred. Scanning electron micrographs showed not only a reduction dispersed-phase size with increased TPP content but also fibrillated links between PLA PBSA phases, signifying compatibilization. Moreover, optimization parameters such sequence time, content,...
In this study, we investigate the adsorption capability of molybdenum sulfide (MoS2)/thiol-functionalized multiwalled carbon nanotube (SH-MWCNT) nanocomposite for rapid and efficient removal heavy metals [Pb(II) Cd(II)] from industrial mine water. The MoS2/SH-MWCNT was synthesized by acid treatment sulfurization MWCNTs followed a facile hydrothermal reaction technique using sodium molybdate diethyldithiocarbamate as MoS2 precursors. Morphological chemical features material were studied...
