Polypropylene (PP) is a polymer used industrially on a large scale. However, the PP has limitations in external use due to its sensitivity to photodegradation, when exposed to the elements. This limits the options of use ...

Currently, seek to technologies for new materials that minimize environmental problems, it leads researchers to develop polymers from renewable and biodegradab le sources, such as cellulose and ...

Polymer (3,4-ethylenedioxythiophene) in association with PSS Poly (4-styrenesulfonic acid) PEDOT: PSS, are a class of materials that associate properties found in plastics with electrical characteristics present in metals. ...

Polyurethanes are applied for many purposes. This wide use is due to the versatility of these polymers, consisting of flexible and rigid segments, whose combination determines their characteristics. Therefore, the main ...

Due to increasing use of polymeric materials in society and the large volume of of those materials disposal in nature, the biodegradable polymers have increased interest in research of materials area. The Polyhydroxybu ...

In recent years, the increasing volume of polymer resin production and use has generated environmental problems caused by the post-consumption disposal of these materials, which become huge amounts of waste due to the ...

Brazil is currently considered the largest producer of sugarcane in the world, which results directly in tons of lignocellulosic biomass residues. The use and recycling of these process residues would reduce the environmental ...

The proper disposal of solid waste has driven studies to enable the use of recycled materials and waste. So, in this work were molded composites using raw materials from industrial waste and evaluated several mechanical ...

One of strong associations between polymers as biomaterials are in field of skin reparation. Polymers are utilized for this purpose, some such as poly (vynil alcohol) (PVA) are used due to characteristics such as ...

Issues related to renewable energy have been increasingly addressed and discussed. In this context, biomass is an alternative for the generation of renewable and available energy. Its use, instead of fossil fuels, helps ...
