Highly hydrophobic flax fabrics with durable properties were prepared using the “dip-coating” method for self-cleaning application. Flax coated a polysiloxane coating via hydrosilylation reaction Karstedt catalyst at room temperature. The displayed highly and (contact angle sliding of about 145° 23°, respectively) good ability certain pollutants excellent durability. Moreover, influence process on mechanical was investigated. A decrease in E modulus an increase tensile stress maximum force...

Flame-retardant flax fabrics were developed using the grafting of phytic acid (PA) through a two-step process. First, functionalized with glycidyl groups employing polymerization methacrylate (GMA) via simultaneous e-beam irradiation procedure. Subsequently, modified treated PA two different techniques: first method involved direct approach, where phosphonic functions reacted groups. The second technique employed coating process, which was based on combination and ethylene glycol diglycidyl...

Abstract Summary: Atom Transfer Radical Polymerization (ATRP) of styrene was carried out at 110 °C using various substituted 2‐bromoisobutyrates as initiators and the homogeneous catalyst CuBr/1,1,4,7,10,10‐hexamethyltriethylenetetramine (HMTETA). Telechelic oligomers were obtained by coupling bromo terminated polymers Cu(0)/PMDETA 90 °C. The products characterized 1 H NMR MALDI‐TOF some unsaturated polymer chains observed. They could originate from either disproportionation reaction or...

Abstract The asymmetry of halloysite surface chemistry was used to perform a selective modification its inner via grafting synthesized styrene/(methacryloyloxy)methyl phosphonic acid copolymer. Fourier transform infrared spectroscopy, thermogravimetric analysis ( TGA ) and pyrolysis gas chromatography/mass spectrometry were evidence quantify the grafting. Then, raw hybrid nanoparticles incorporated in polystyrene PS )/polyamide‐11 PA11 blends (80/20 60/40 wt%). Scanning electron micrographs...

Cellulose from cotton fibers was functionalized through a dissolution–regeneration process with phosphonate-based ionic liquids (ILs): 1,3-dimethylimidazolium methylphosphonate [DIMIM][(MeO)(H)PO2] and 1-ethyl-3-methylimidazolium methylphoshonate [EMIM][(MeO)(H)PO2]. The chemical modification of cellulose occurred transesterification reaction between the methyl phosphonate function ILs primary alcohol functions cellulose. resulting structure amount grafted phosphorus were then investigated...
