“…Organic‐inorganic hybrid materials have aroused widespread attention in materials science and chemical research in the last decades owing not only to their diverse and interesting structures but also to their potential application in magnetism, luminescence, electronics, catalysis, and flame‐resistant fibers etc. Many important properties of organic–inorganic hybrid materials are based on their structures and topologies.…”

Three new tin coordination compounds (4,4'‐Hbipy)2[Sn2(C2O4)3] (1), (4,4'‐H2bipy)[Sn(C2O4)2] (2), and SnCl2(4,4'‐bipy) (3) were synthesized under hydro‐(solvo‐)thermal conditions and their crystal structures were determined by single‐crystal X‐ray diffraction. Compound 1 exhibits a ionic structure based on discrete [4,4'‐Hbipy]+ cations and [Sn2(C2O4)3]2– anions. These two units are linked via N–H···O hydrogen bonds to form a pseudo‐one‐dimensional zigzag hydrogen‐bonded chain. In compound 2, four‐coordinate Sn atoms form monomeric tin dioxalato complexes, which are connected to the doubly protonated [4,4'‐H2bipy]2+ cations through N–H···O hydrogen bonded to give a one‐dimensional zigzag hydrogen‐bonded chain. Compound 3 forms a three‐dimensional hydrogen‐bonded network, in which 1∞[SnCl2(4,4'‐bipy)] linear chains are interconnected to each other by C–H···Cl hydrogen bonding. The solid‐state UV/Vis/NIR diffuse reflectance spectroscopy shows that three compounds are broadband semiconductors. The thermogravimetric analysis evidences the thermal stability of the three compounds up to 175, 201, and 246 °C, respectively.

“…As far as textile applications are considered, usually the sol-gel technique has been proposed for conferring new functional properties to fabrics, such as antimicrobial or UV radiation protection [3], dye fastness [4], anti-wrinkle fi nish [5] and hydrophobicity [6]. With the goal of improving fl ame resistance of fabrics, in the last years, textile fi nishing by sol-gel method has been systematically studied [7][8][9][10][11][12][13]. Th e treatment of textile materials with hydrolysed metal alkoxide solutions is an excellent tool to convey new properties to polymer surfaces, particularly if organic components, like phosphorous-based chemicals, are incorporated into the formulation [9].…”

“…Previous results demonstrated that sol-gel processes could be exploited as fi reproof treatments with lower environmental impact for textile fabrics as compared with common fl ame retardant processes [9]. In this composition, the hybrid organic-inorganic materials (HOIMs) [8,9,14] show the properties of both the phases. Th erefore, the thermal stability at high temperatures, proper of inorganic constituents, can be combined with the fl ame retardancy provided by organic phosphorusbased compounds.…”

This work investigates the use of organic-inorganic sol-gel coatings based on silica and phosphorous compounds for providing cotton fabrics with fl ame retardant features. To this aim, diethylphosphatoethyltriethoxysilane precursor was employed for the synthesis of several sols in combination with diff erent chemical additives. Sols were reacted with azo-based compounds and repeatedly applied onto the cellulosic substrate in a multilayer assembly, aiming at assessing the eff ect of the concurrent presence of Si, P and N on the overall fi re behaviour of the fabric. In order to evaluate the fl ame retardancy of treated cellulosic fabrics, fl ammability tests were carried out. The obtained results showed that the phosphorus-silica coating is able to promote the formation of a stable char that acts as insulator barrier. Finally, an additive P-N eff ect of the ceramic oxide coating in terms of increased residue and decreased heat release rate and total burning time was observed in cone calorimetry tests.

“…It is elucidated that these compounds produce siliceous char layer which delays the spread of fire and causes a remarkably larger reduction in materials' flammability during combustion [19,20], especially coupled with other flame-retardant elements [18,[21][22][23][24]. Therefore, silicone-based compounds have great potential as flame inhibitors for cotton fabrics, and it is of interest to develop eco-friendly new flame retardants containing Si, P, and N elements [25,26].…”

A novel flame-retardant agent, nitrogenand phosphorus-containing polysiloxane [(IB-co-N-MDPA)PDMS] was synthesized, and it was employed on cotton fabrics. Cone calorimeter testing showed that the treated cotton fabric with (IB-co-N-MDPA)PDMS became less flammable with longer time to ignition and lower value of HRR, THR, EHC and mass loss. Thermogravimetric analysis demonstrated that (IB-co-N-MDPA)PDMS improved the thermal and thermo-oxidative stability of cotton fabric with fewer flammable volatiles, and more char is produced during combustion. Scanning electron microscopy showed that the surface of treated cotton fabric after combustion was covered by a compact char layer which indicated that (IB-co-N-MDPA)PDMS favored the formation of char as evidenced by the FTIR of residues. Furthermore, EDS analysis results demonstrated that the concurrent presence of Si and P in flame retardant effectively enhance the flame retardancy of cotton fabric with the remarkable amount of Si and P elements that were still present on the surface of fibers after combustion.
