Halochromic silk fabric as a reversible pH-sensor based on a novel 2-aminoimida...
Ribeiro, Ana Isabel; Vieira, Bárbara Marques; Alves, Cátia Sofia Pereira; Silva, Bárbara; Pinto, Eugénia; Cerqueira, Fátima; Silva, RenataTextiles are important components for the development of lightweight and flexible displays useful in smart materials. In particular, halochromic textiles are fibrous materials with a color-changing ability triggered by pH variations mainly based on pH-sensitive dye molecules. Recently, a novel class of 2-aminoimidazole azo dyes was developed with distinct substituent patterns. In this work, silk fabric was func...
Enhancing the antimicrobial efficacy of polyester fabric impregnated with silve...
Ribeiro, Ana Isabel Ferreira; Mehravani, Behnaz; Magalhães, Cátia; Negreiros, Talita Nicolau Oliveira Vidal; Melro, Liliana Sofia Silva Ferreira PintoThe functionalization of polyester fabric (PES) with antimicrobial agents presents huge number of potential applications in advanced products. However, the lack of functional groups and the high PES hydrophobicity make the functionalization processes costly, prolonged and requires the use of polluting chemical compounds. In this work, dielectric barrier discharge (DBD) plasma treatment, an affordable and enviro...
Stabilization of silver nanoparticles on polyester fabric using organo-matrices...
Ribeiro, Ana Isabel Ferreira; Shvalya, Vasyl; Cvelbar, Uroš; Silva, Renata; Marques-Oliveira, Rita; Remião, Fernando; Felgueiras, Helena PradoAntimicrobial textiles are helpful tools to fight against multidrug-resistant pathogens and nosocomial infections. The deposition of silver nanoparticles (AgNPs) onto textiles has been studied to achieve antimicrobial properties. Yet, due to health and environmental safety concerns associated with such formulations, processing optimizations have been introduced: biocompatible materials, environmentally friendly...
