The article deals with the preparation, properties and the usage of polymer barrier films. The problem of exfoliation and dispersion of the filler in the polymer matrix and mechanical properties of barrier films is discussed. This problem is connected with the use of nanofiller either in the polymer matrix or on the surface of prepared films. Together the evaluating comparison of used nanofille...

Montmorillonite has been widely used in remediation of toxic metals. However, for the safety soil ecosystem, impact this technology on microorganisms is still unclear. Here, influence nano-montmorillonite immobilization, accumulation cadmium, and microbial activity a soil–plant system was investigated. The results revealed that treatments reduced cadmium bioavailability uptake by oilseed rape. ...

* Corresponding Author Email: [email protected] Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT)...

By referring to the domestic and foreign researches on color anti-skid pavement, composition of epoxy resin coating material for antiskid pavement is designed. The purpose experiment analyze effect nano-modified by adding 2.5% nano-organic montmorillonite modifier existing surface material. Test compare change mechanical properties binder before after nano-modified. Then nano-modification analy...

this study was conducted to enhance the antimicrobial properties and water absorption of sanitary papers. for this purpose, montmorillonite nano clay with bentonite brand (has a layered structure in which its thickness is nano metric), was processed with homogenizer to achieve a stable colloidal system with nanometer dimensions of particle size. then, different weight levels of raw and homogeni...

Ultraviolet radiation is the main cause of degradation in asphalt pavement. To improve performance pavement used strong ultraviolet (UV) region western plateau, China, this study explores effects adding nano-montmorillonite and carbon black to SBS-modified asphalt. Through conventional index detection, dynamic shear rheological tests, low-temperature bending creep UV aging high- performance, fa...

In this survey adsorption of some heavy metals such as cobalt and lead on montmorillonite and montmorillonite/copper oxide nano-composite is reported. Adsorption percent and adsorption capacity were studied under different conditions such as pH concentration of metal ions amount of clay and interaction time. The results show that an increase in absorption percent and absorption capacity wit...

In an attempt to develop a soybean-protein wood adhesive with improved water resistance and good technical applicability, soybean protein was first degraded under strong alkali conditions and then subjected to chemical crosslinking combined with nano-modification. Results of plywood evaluation, GPC analysis, and XRD determination indicated that a soybean-protein adhesive that could bear 28 h bo...
