A facile approach to achieve multifunctional polyethylene terephthalate fabrics with durable superhydrophobicity, photocatalysis and self-quenched flame retardance

Abstract

The reports about polyethylene terephthalate (PET) fabrics with durable superhydrophobicity and flame retardance were very limited. In this paper, durable superhydrophobic, photocatalytic, flame-retardant (FR) PET fabrics were firstly fabricated by...

On the Development of Ultradurable Extremely Water-Repellent and Oleophobic Soot-Based Fabrics with Direct Relevance to Sperm Cryopreservation

“…The soot’s reinforcement with cyanoacrylate glue imparts extraordinary robustness of this intrinsically brittle substance and for the first time since the beginning of research activities in this scientific field, the macroscale deposition of non-delaminating scratching-resistant soot of adhesion class 4B (i.e., less than 5% of the surface is peeled-off) seems feasible (although similar result is achievable with wax candles, , their thin flame front fails to meet the criteria for scalability, i.e., wings of aircraft are unrealistic to be treated by a candle flame). Furthermore, the soot fabrics remain unaffected by high-velocity water jetting (∼25 m/s), manual squeezing and the impact of 200 g steel weights and liquid nitrogen (see Videos S3–S6 in the Supporting Information), which ranks them next to other resilient water-repellent fabrics, whose methods of synthesis comprise multiple chemicals and/or sophisticated equipment. ,,, …”

“…Until very recently, the commercial use of hydrophobic chemical modifiers, endowing water repellency to any preliminary roughened solid surface, has been hampered due to the low chemical, thermal and mechanical durability of the forming superhydrophobic layer. , Fortunately, the expanding perception of our community that the scientific innovations should ultimately bring societal benefits, has stimulated many scholars to develop ultradurable non-wettable materials capable of withstanding multiple adverse environmental effects and industrial processes. ,− At present, the incorporation of a variety of fluorine and/or silane-based chemicals into the matrix of TiO 2 , SiO 2 , ZnO, polydimethylsiloxane, Fe 3 O 4 /Ag and so forth nanocomposites has led to the launch of unique extremely water-repellent thin films exhibiting exceptional mechanical strength toward abrasive wear, corrosive liquids, UV irradiation, sudden thermal fluctuations and flame exposure, while concurrently supporting oil–water separation, antimicrobial, photocatalytic or anti-icing properties. ,− Nonetheless, the scarce examples for robust superhydrophobic coatings encompassing both icephobic and anti-fouling features remain a major obstacle to the sustainable development of medicine, aerospace and shipbuilding industries. ,, …”

Layer-by-Layer Self-Assembly Coating for Multi-Functionalized Fabrics: A Scientometric Analysis in CiteSpace (2005–2021)

“…The flame retardancy of fabrics is enhanced because the inorganic coatings act as thermal shielding barriers during combustion, which can effectively hinder the transmission of heat, oxygen, mass and volatile products from the underlying fabric to the atmosphere [ 40 , 41 ]. Many inorganic nanoparticles have been utilized in coatings, including montmorillonite [ 42 , 43 , 44 , 45 , 46 ], carbon nanotubes [ 45 , 47 , 48 , 49 ], silica [ 42 , 50 , 51 , 52 , 53 ] and titanium dioxide [ 54 , 55 , 56 ]. The second coating can form a stable carbon layer during combustion.…”

Eco-Friendly and Facile Integrated Intumescent Polyelectrolyte Complex Coating with Universal Flame Retardancy and Smoke Suppression for Cotton and its Blending Fabrics

“…Despite many benefits of the LbL assembly method, the fussy deposition processes make it difficult for large-scale production. 25 Recently, an oppositely charged polyelectrolyte complex (PEC) was deposited on fabrics to simplify the coating processes. 25−27 First, PEC with an appropriate pH and concentration was water-soluble and could be deposited on the fabrics via immersion.…”
