Poly(ethylene terephthalate) (PET) nanocomposites containing rod-like silicate attapulgite (AT) were prepared via in situ polymerization. It is presented that PET chains identical to the matrix have been successfully grafted onto simple organically pre-modified AT nanorods (MAT) surface during the in situ polymerizati…
Poly(lactic acid) (PLA) based nanocomposites based on 5 wt.% of an organically modified montmorillonite (CLO), unmodified sepiolite (SEP) and organically modified zirconium phosphonate (ZrP) were obtained by melt blending. Wide angle X-ray scattering (WAXS) and scanning electron microscopy (SEM) analysis showed a diff…
The addition of small amounts (up to 9 wt%) of chitin microsized particles, originating from shellfish waste, to carboxylated styrene-butadiene rubber (XSBR) matrix (as received and annealed to 100C) has been studied. In particular, this study concentrated on their mechanical (creep investigation by nanoindentation an…

Nanocomposites consisting of poly(styrene-b-butadiene-b-styrene) (SBS) and polyhedral oligomeric silsesquioxanes (POSS) were prepared using a solvent dispersion method. POSS molecules were functionalised with two dichlorotriazine reactive dyes (CI Reactive Blue 4, CI Reactive Red 2) prior to compounding. Infrared spec…
A porous nanocomposite based on polypyrrole (PPy) and sodium alginate (SA) has been synthesized by easy, inexpensive, eco-friendly method. As prepared nanocomposite showed fibrillar morphology in transmission electron microscopic (TEM) analysis. The average diameter of ~100 nm for the nanofibers was observed from scan…
Wood flour and natural fibers are used in increasing quantities mainly for the reinforcement of commodity polymers Such reinforcements have many advantages over particulate fillers or glass fibers; they increase stiffness considerably, they are obtained from renewable resources, are available in abundant quantities, c…
The possibility to use natural polymer as ionic conducting matrix was investigated in this study. Samples of agarbased electrolytes with different ionic liquids were prepared and characterized by physical and chemical analyses. The ionic liquids used in this work were 1
In this study, the effect of polymeric Methylene Diphenyl Diisocyanate (pMDI) chemical treatment on kenaf (Hibiscus cannabinus) reinforced thermoplastic polyurethane (TPU/KF) was examined using two different procedures. The first consisted of treating the fibers with 4% pMDI, and the second involved 2% NaOH + 4% pMDI.…
Terephthalate (TA) intercalated layered double hydroxides (LDHs) were synthesized using hydroxides as raw materials, and poly(ethylene terephthalate) (PET)/LDH nanocomposites with different contents of TA intercalated LDHs were prepared by in-situ polymerization. The structure, morphology and thermal property of PET/L…
The object of this study was to investigate how different decreasing of pH regimes during microencapsulation process with melamine-formaldehyde (MF) resin affects the composition, morphology and thermal stability of microcapsules containing a phase-change material (PCM). Technical butyl stearate was used as PCM. Micro…
Mechanical properties and drug release behavior were studied for three biodegradable polyester matrices (polycaprolactone, poly(nonamethylene azelate) and the copolymer derived from 1,9-nonanediol and an equimolar mixture of azelaic and pimelic acids) reinforced with polylactide (PLA) fibers. Electrospinning was used…

Novel blends of acrylonitrile butadiene rubber (NBR) and polyurethane-silica (PU-SiO 2 ) hybrid networks have been prepared by melt blending. The PU-SiO 2 hybrid networks were formed via the reaction of NCO groups of NCO-terminated PU prepolymer and OH groups of SiO 2 in the absence of an external crosslinking agent (…
Upgrading of polypropylene waste was performed by different composite technologies, in order to improve the flame retardancy combined with preserved or improved mechanical properties. The polymer waste of density below 900 kg/m 3 is originated from end-of-life vehicles (ELV) after comminution, density separation and c…
Some new Polystyrene (PS) nanocomposites were prepared by using two Polyhedral Oligomeric Silsesquioxanes (POSSs), namely RR' 7 (SiO 1.5 ) 8 (where R = 4-methoxyphenyl or 2,4-difluorophenyl and R' = cyclopentyl), as fillers, and their degradation was studied to investigate the effect of the electron-donor or electron-…
Tin-doped Indium oxide (ITO) thin films were prepared by sol-gel dip-coating technique using low-cost metal salts and organic solvents. The coated films were treated without annealing or annealed at 400°C and 600°C in 3% H 2 /97% N 2 mixtures atmosphere. Microstructure, optical, and electrical properties of the prepar…
