Preparation of polymer-based nanocomposites by different routes

Since the eighties, polymeric nanocomposites have been intensely investigated due to the performance improvement achieved when a small amount of nanosized particles are added to a polymer matrix. The remarkable changes on physical and mechanical properties of polymers due to the addition of inorganic solid nanoparticles (typically in form of fibres, flakes, spheres or fine particles) is explained by the huge su...

Combining asphalt-rubber (AR) and fast-pyrolysis bio-oil to create a binder for...

Best paper award of the conference ; The bio-oil from fast pyrolysis is mainly a product of the recycling of waste materials. This is a viscoelastic material, and after a heat treatment it has a viscosity similar to many types of asphalt used in the paving industry. Although bio-oil showed very good high temperature performance, the same was not verified at low temperatures. Therefore, GTR from cryogenic milli...

Development of a quasi-dry electrode for EEG recording

The present work reports on the development of a novel polymer-based electrode prototype for electroencephalography (EEG). The new electrode concept lies between the classic “wet” and “dry” electrodes, allowing addressing most of their drawbacks, while keeping the advantages of both. A localized skin hydration effect at the electrode/scalp contact point is achieved by the release of a small amount of a moisturi...

Phosphorus removal from eutrophic waters with an aluminium hybrid nanocomposite

An excess of phosphorus (P) is the most common cause of eutrophication of freshwater bodies. Thus, it is imperative to reduce the concentration of P to prevent harmful algal blooms. Moreover, recovery of P has been gaining importance because its natural source will be exhausted in the near future. Therefore, the present work investigated the removal and recovery of phosphate from water using a newly developed h...

Phosphorus removal from eutrophic waters with a polymer nanocomposite containin...

Intensive agriculture production and industrial expansion are causing an increase on nutrient release (phosphorus and nitrogen), resulting in over-enrichment of soils and aquatic bodies. The nutrient over-enrichment of aquatic ecosystems leads to an excessive biomass growth. Eutrophication processes have negative effects on biology, chemistry and human use of lakes and rivers, namely by cyanobacteria toxins...

Effect of weathering conditions on the degradation behaviour of ABS

Influence of EVA molar mass on preparation of EVA-g-PCL biobased copolymers

The rapid growth of plastic production is considered as a serious source of environment pollution. Approximately 100 million tons of plastics are produced each year and within a short period of time almost half are disposed to the environment. A way to overcome this problem would be the use of biodegradable polymers. Several attempts are made to replace synthetic polymers by biodegradable ones. Nevertheless, th...
