DBD plasma-treated polyester fabric coated with doped PEDOT:PSS for thermoregul...
Magalhães, Cátia; Ribeiro, Ana Isabel Ferreira; Rodrigues, Rui; Meireles, Ângela; Alves, Alexandra C.; Rocha, João Pedro Costa; Pedroso de Lima, FábioThe manufacturing process of thermoregulation products with polyester (PES) fabric and conductive polymers such as poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate) (PEDOT:PSS) with proper wearability, comfort, and high performance is still a challenge due to low adhesion, environment instability and nonuniform coatings. This study presents a simple and effective method for producing thermoreg...
Bacterial nanocellulose as a versatile scaffold for biomedical applications: sy...
Melro, Liliana Sofia Silva Ferreira Pinto; Alves, Cátia Sofia Pereira; Fernandes, Marta Susana Machado; Rocha, Sofia Gomes; Mehravani, BehnazBacterial nanocellulose (BNC) consists of nanofibres of cellulose randomly entangled during their synthesis by particular bacterium cells during fermentation. Thus, it may be regarded as a unique three-dimensional of pure cellulose that is consolidated during the generation of the fibres by their microbiological factories. The metabolic synthesis and purification processes are approached, underscoring its poten...
Biosynthesis of silver nanoparticles on polypropylene nonwovens: towards antimi...
Marković, Darka; Tomšič, Brigita; Zille, Andrea; Ribeiro, Ana Isabel Ferreira; Ilic‐Tomic, Tatjana; Tadić, Vanja; Simončič, Barbara; Radetić, MajaThe utilization of disposable face masks is an essential approach to mitigate the transmission of microorganisms. Composed mainly of polypropylene (PP) nonwoven material, these masks do not exhibit any antimicrobial properties. This study examines the feasibility of employing Ag-based nanoparticles (NPs) as an antimicrobial agent. To activate the chemically inert PP samples, corona discharge was applied at atmo...
Gel electrolytes in the development of textile-based power sources
Ribeiro, Ana Isabel Ferreira; Alves, Cátia Sofia Pereira; Fernandes, Marta Susana Machado; Abreu, José Emanuel Ferreira; Pedroso de Lima, FábioThe interest in flexible and wearable electronics is increasing in both scientific research and in multiple industry sectors, such as medicine and healthcare, sports, and fashion. Thus, compatible power sources are needed to develop secondary batteries, fuel cells, supercapacitors, sensors, and dye-sensitized solar cells. Traditional liquid electrolytes pose challenges in the development of textile-based electr...
Alternative organic solvents for elastane removal from textile waste: a case st...
Silva, Ana Catarina; Azevedo, Tiago Jorge Mendonça Pinto; Ribeiro, Ana Isabel Ferreira; Chaves, Diego Morais; Fangueiro, Raúl; Ferreira, Diana P.The increasing demand for sustainable textile recycling has driven the search for effective methods to separate and recover valuable materials from fabric waste. Elastane, a widely applied synthetic polymer in the textile industry due to its flexibility and durability, presents considerable environmental challenges after the material life cycle. Thus, the development of effective methods for elastane degradatio...
Reinforcing cotton recycled fibers for the production of high-quality textile s...
Azevedo, Tiago Jorge Mendonça Pinto; Silva, Ana Catarina; Machado, Gonçalo; Chaves, Diego Morais; Ribeiro, Ana Isabel Ferreira; Fangueiro, RaúlThe textile industry is under increasing pressure to adopt sustainable practices due to the significant environmental impacts associated with fiber production, including high energy consumption, water usage, and substantial greenhouse gas emissions. The recycling of textile waste, particularly cotton, is a promising solution that has the potential to reduce landfill waste and decrease the demand for virgin fibe...

Meeting circular economy by producing leather from (sarda sarda) fish
carvalho, Isabella; Pedroso de Lima, Fábio; Ribeiro, Ana Isabel Ferreira; Fernandes, Marta Susana Machado; Zille, AndreaFollowing the principles of circular economy and waste reduction, recycling fish skin is an interesting and sustainable practice. However, traditional tanning procedures give rise to many sustainability concerns throughout the process. The most serious of these is chemical pollution as traditional tanning frequently uses harmful materials like chromium salts, which can contaminate soil and water supplies and en...
Plant-assisted synthesis of ag-based nanoparticles on cotton: Antimicrobial and...
Krkobabić, Ana; Radetić, Maja; Zille, Andrea; Ribeiro, Ana Isabel Ferreira; Tadić, Vanja; Ilic-Tomic, Tatjana; Marković, DarkaThe syntheses of Ag-based nanoparticles (NPs) with the assistance of plant extracts have been shown to be environmentally benign and cost-effective alternatives to conventional chemical syntheses. This study discusses the application of Paliurus spina-christi, Juglans regia, Humulus lupulus, and Sambucus nigra leaf extracts for in situ synthesis of Ag-based NPs on cotton fabric modified with citric acid. The pr...
Plasma in textile waste water treatment
Oliveira, Marta Susana Fernandes; Fernandes, Rui Daniel Vilaça; Padrão, Jorge; Melro, Liliana Sofia Silva Ferreira Pinto; Alves, Cátia Sofia Pereira[Excerpt] Water is an essential resource for all life forms on this planet. It is also a critical source of anthropogenic social and economic development [1]. Nevertheless, freshwater scarcity is a real issue that is felt worldwide. It is estimated that by the year 2050 around 6 billion people will suffer from potable water scarcity [2]. The depletion of freshwater is a consequence of rapid population growth, c...
