Polyethylene terephthalate (PET) is a very stable polymer widely used in the modern world. Due to its stability, this can remain environment for several years before complete degradation. The glycolysis reaction of PET has emerged as green approach obtain monomer, thus avoiding such environmental problems and adding value waste. In work, waste was depolymerized by using ultrasmall cobalt nanoparticles (1.5 wt %) catalyst production bis-2-hydroxyethyl (BHET). A capping agent (tannic acid, TA)...
A hybrid material on the carbon paste electrode exhibited a greater electroactivity for determination of an endocrine disruptor.
The use of Metal-Organic Frameworks (MOF) such as HKUST-1 in textiles is an alternative with regard to the development technologies that are increasingly seeking for functionalities, mainly fields health and hygiene, named biofunctional fabrics. However, application MOF under surface wool fiber can lead a low durability finish due its fixation. Thus, this project aims perform direct synthesis HKUST fiber, so product good washing be obtained. purpose study was incorporate metal-organic...
Polyester fibers (PES) are the most consumed textile due to their low water absorption; non-ionic character and high crystallinity. However, chemical structure, interactions between polyester, finishing products, dyes quite challenging. We report on use of ozone modify surface polyester with goal improving interaction modified compounds dyes. used C.I. Disperse Yellow 211 dye ozone-treated fabrics evaluated effects treatment using FTIR-ATR, Raman spectroscopy, SEM imaging, rubbing tests,...
We present a review of current research on promising flame retardants using specific methods applying metal–organic frameworks (MOFs) to the highly flammable fibrous surface cotton fabric. In this review, we initially address reasons why search for new has becomes critically important in textile finishing, area responsible adhering functionalities substrates. This addition characteristics is closely linked nature fibers, so reason improvement fabric relation retardancy discussed....
The low thermal stability of cellulose presents unique technological challenges to the formulation wood and plastic composites that are compatible processable. For this, hydrothermal modification is a well-established technology for improving dimensional durability wood's components, in addition providing better interaction with polymer. This study produced polymer which hydrothermally treated waste fibers (WT) reinforce recycled polypropylene (RPP) matrix. Wood were selected by grain size...
ABSTRACT Textile finishes have long been utilized to impart novel functional properties fabrics. These functionalizations can be applied substrates through various methods. However, one of the most prevalent forms application is via encapsulation systems, which offer protection active ingredients against potential adversities. microcapsule delivery vehicles find across diverse fields, spanning pharmaceutical, cosmetic, and textile industries. Within sector specifically, such structures...
Silica-coated magnetite (Mag-Sil) was prepared by the co-precipitation method using sodium metasilicate under an inert atmosphere and a fine pH control. Cetyltrimethylammonium bromide (CTAB) adsorbed onto Mag-Sil aiming at decreasing natural hydrophilicity of silica surface, allowing study hydrophobic interaction with dodecylbenzenesulfonate (SDBS) to be carried out. presented low surface Brönsted acidity once point zero charge 7.5. The synthesized materials were characterized X-ray...
In this study, preparation of metal-organic frameworks (Cu<sub>3</sub>BTC<sub>2</sub>, Fe<sub>3</sub>BTC<sub>2</sub>, Ni<sub>3</sub>BTC<sub>2</sub> and Co<sub>3</sub>BTC<sub>2</sub>) (BTC = benzene-1,3,5-tricarboxylate) was performed by five different synthetic methods (solvothermal under autoclave, reflux, domestic microwave, ultrasonic, mechanochemical conditions) the results were compared in order to evaluate advantages disadvantages each method with a focus on microwave method.

A new green synthesis route is proposed for obtaining a mesoporous material using sugarcane bagasse ash as the silica source.
New recycling alternative for multilayer films was successfully presented. Food packaging formed from different materials is difficult to recycle. The use of aluminum, glass, paper, paints, varnishes, and other in the rolling processes plastic intended optimize efficiency packaging. Nevertheless, these prevent because they become contaminants process. multilayered containing poly (ethylene terephthalate) PET, (ethylene) PE aluminum used as filler preparation composites with post-consumer...
