This article presents a simple, one-step, in situ generation of silver nanoparticle-functionalized fabrics with antibacterial properties, circumventing the conventional, multistep, time-consuming methods. Silver nanoparticle formation was studied with a library of capping agents (branched polyethylenimine [BPEI] of molecular weight [Mw] 10,000 and 25,000, polyvinylpyrrolidone, polyethylene glyc...

Fabrics are typical porous material and can be treated as mixtures of fibers and air. There is no clearly defined boundary and is different from a classical continuum for fabrics. It is complex to proceed with the theoretical analysis of fabric behavior. There are two main reasons (Hearle et al., 1969) for developing the geometrical structures of fabrics. One is to be able to calculate the resi...

Urban planning, in particular on protected landscape areas, demands an increasing role of public participation within the frame of the efficiency of sustainable planning process. The development of urban planning actions in Protected Landscape areas, as Sintra-Cascais Natural Park, should perform a methodological process that is structured over distinct sequential stages, providing the developm...

Highly-flexible thermoelectric fabrics were fabricated based on a layered structure, composed of a thin active layer of self-assembled tellurium nanorods and a substrate layer of polyvinylidene fluoride. The resulting thermoelectric fabrics show a high room temperature power factor of 45.8 μW m(-1) K(-2), which opens a new avenue to fabricate highly-flexible sustainable energy sources.

The cellulosic fabrics bearing the porphyrin as a photo-sensitizer were done in order to prepare efficient polymeric materials for antimicrobial applications. The obtained porphyrin-grafted cellulosic fabrics were characterized by ATRFTIR, DRUV spectroscopy, TG and SEM image. The antimicrobial activity of the products was tested under visible light irradiation against Staphylococcus aureus, Pse...

Silk fabrics were modified by a treatment of silver nitrate solution (AgNO3) and polyvinylpyrrolidone (PVP) as a stabilizer then exposure to γ-irradiation to create antibacterial properties. Effects of the absorbed dose on treated fabrics were investigated. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) patterns were used to confirm the presence of silver nanoparticles (AgNP...
