Nanocomposites of poly(lactic acid) with sepiolite needles (5 wt.%) were evaluated in terms the mechanical and biofilm formation properties. The nanocomposite exhibited higher values Young�s modulus tensile strength at break compared to PLA, without detriment percent elongation break. These improvements related high aspect ratio nanoclay, polymer-clay interactions, degree dispersion. growth Pse...

Inverse vulcanisation stabilises polymeric sulfur to synthesise high content polymers. vulcanised polymers were reinforced with carbon black, cellulose microfibres and nanoclay increase tensile strength.

A superoxide dismutase mimicking nanocomposite of remarkable functional and colloidal stability was developed by sequential adsorption polyelectrolytes metal complexes on nanoclay particles.

Here we describe a unique process that achieves complete defluorination and decomposition of perfluorinated compounds (PFCs) which comprise one of the most recalcitrant and widely distributed classes of toxic pollutant chemicals found in natural environments. Photogenerated hydrated electrons derived from 3-indole-acetic-acid within an organomodified clay induce the reductive defluorination of ...

The present paper reports the successful elaboration of exfoliated plasticized starch-based nanobiocomposites. This was made possible by using cationic starch as a new clay organomodifier to better match the polarity of the matrix and thus to facilitate the clay exfoliation process. To demonstrate the efficiency of this new approach, either natural (MMT-Na) or organomodified (OMMT-CS) montmoril...

This study presents methods for treating a kind of nanoclay and investigates the effects of methylaluminoxane (MAO) exposure time and or dodecylamine (DDA) reflux time on in-situ polymerization of ethylene in the presence of nanoclay and examines the morphology and properties of the prepared polyethylene/clay nanocomposites. The results revealed that by increasing MAO exposure time productivity...

modified bituminous materials can bring real benefits to highway maintenance/construction, in terms of better and longer lasting roads, and savings in total road life castings. this paper present the effect of there novel modifier as precipitated calcium carbonate (pcc) and two type of nanoclay on rheological properties of bitumen binder. various blends of modifier and bitumen were selected and...
