Iongels have attracted much attention over the years as ion-conducting soft materials for applications in several technologies including stimuli-responsive drug release and flexible (bio)electronics. Nowadays, iongels with additional functionalities such as electronic conductivity, self-healing, thermo-responsiveness or biocompatibility are actively being searched for high demanding applications. In this work, we present a simple and rapid synthetic pathway to prepare hyperelastic and thermoreversible iongels. These iongels were prepared by supramolecular crosslinking between polyphenols biomolecules with a hydroxyl-rich biocompatible polymer such as poly(vinyl alcohol) (PVA) in the presence of ionic liquids. Using this strategy, a variety of iongels were obtained by combining different plant-derived polyphenol compounds such as gallic acid, pyrogallol, and tannic acid with imidazolium-based ionic liquids, namely [C 2 mim][N(CN) 2 ] and [C 2 mim][Br]. A suite of characterization tools was used to study the structural, morphological, mechanical, rheological and thermal properties of the supramolecular iongels. These iongels can withstand large deformations (40 % under compression) with full recovery, revealing reversible transitions from solid to liquid state between 87 to 125 °C. Finally, the polyphenol-based thermoreversible iongels shows appropriated properties for their potential application as printable electrolytes for bioelectronics.

“…In our previous study [3], a nonformaldehyde P-N synergetic FR system, PVP (PR)-P-DCDA was synthesized by polyvinyl alcohol, hydrophilic polyester resin, phosphoric acid, and dicyandiamide and applied to 100% polyester, 100% cotton, and 50/50% cotton/polyester (Co/PET) fabrics by conventional padding method.…”

“…Compared to untreated and Fire-off/CA treated fabrics, Fireoff/CA treated fabrics showed a reducing of OH density peak, quite likely because of the chemical reaction between cellulose and citric acid. For treated CO/PET blends with Fire-off/CA and Fire-off/PA/CA characteristics IR absorptions of Fire-off (PVP(PR)-P-DCDA) are easily identified at around 3333 (-NH 2 ), 1235 (P=O), 904 (P-O-H), 825 (P-N) and 460 cm -1 (P) [3]. However, Fire-off/PA/CA treated fabrics have larger and sharper peaks 1235, 1015, 904, 825 and 460 cm -1 (which are in silica region) than Fireoff/CA treated fabrics.…”

In the present study, a new flame retardancy and non-slip finishing system in one step was developed for cotton/polyester (Co/PET) fabrics. Recipes including P-N synergetic FR agent, PVP (PR)-P-DCDA (Fire-off), polysilicic acid and citric acid combinations were developed and applied to cotton and Co/PET fabrics by impregnation method. Flame retardancy (FR) properties and seam slippage resistance of treated fabrics with Fire-off/polysilicic acid systems were investigated. In addition, characterization analysis such as Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC) were performed and tensile properties of treated fabrics were tested in order to detect any changes on mechanical properties of fabrics after treatment. Results demonstrated that Fire-off/ polysilicic acid treatment leads good FR properties (LOI ˃27) and seam slippage resistance (warp: 2.2 mm, weft 1.2 mm) with superior ease of application in one-step process.

The present paper investigates the capability of MCC and TGA methods by testing the thermal performance of commercially available flame-retardant chemical called Fire-off on polyethylene terephthalate (PET) and cotton (Co) fabrics and their corresponding blends (Co/PET). Fire-off was applied to the fabric through impregnation method and the resulting properties of these fabrics were assessed in terms of combustion behavior by use of micro combustion calorimeter (MCC) and thermogravimetric analysis (TGA). TGA results revealed that Fire-off could greatly enhance char residues of cotton, PET and Co/PET fabrics at high temperature region. MCC results indicated that Fire-off treatment could significantly decrease the heat release capacity (HRC), heat release rate (HRR), total heat release rate (THR) and peak heat release rate (pHRR) of cotton, PET and Co/PET fabrics. According to comparison results, a near-perfect agreement between MCC and TGA data were found in terms of degradation temperatures and mass loss rates of fabric samples ARTICLE HISTORY
