Mixed phenolic-polyurethane-type rigid foams were developed using tannin-furfuryl alcohol natural materials co-reacted with polymeric isocyanate in the proportions imposed by limitations inherent to continuous industrial plants for polyurethane foams. A variety of different copolymerization oligomers formed. Urethanes appeared have been formed two flavonoid tannin sites, mainly at hydroxyl group C3, but also, although less, on phenolic groups oligomers. are also (i) glyoxal formulation, be...
SUMMARY There is a need for ground‐breaking technologies to boost crop yield, both grains and biomass, their processing into economically competitive materials. Novel cereals with enhanced photosynthesis assimilation of greenhouse gasses, such as carbon dioxide ozone, tailored straw suitable industrial manufacturing, open new perspective the circular economy. Here we describe vision, strategies, objectives BEST‐CROP, Horizon‐Europe United Kingdom Research Innovation (UKRI) funded project...
ABSTRACT The main objective of this study is devoted to the development new insulating and ignifuged miscanthus fibers (Mf)/recycled textile (RTf) reinforced biocomposites (BCs) using chitosan as polysaccharide‐based binder aluminum trihydroxide (ATH) fillers while focusing on fire behavior. To achieve goal, a preliminary was carried out flame retarded chitosan‐based films with various ATH‐filler ratios (20, 33, 50, 60 wt %). ATG pyrolysis‐combustion flow calorimeter analysis showed...
Tannin/furanic rigid foam made from raw materials of natural origin could be used to replace polyurethane and phenolic foams in many future applications. In this study, diethyl ether, pentane, a mixture the two were prepare tannin/furanic having different microstructures. It was found that bulk density significantly extended, up 180 kg/m3. The cell size pentane larger than ether with comparable density; however, both presented sudden increase when decreased. thermal conductivity mechanical...
The objective of this work was to compare the material recovered from different chemical recycling methodologies for thermoplastic acrylate-based composites reinforced by basalt fabrics and manufactured vacuum infusion. Recycling done via dissolution with a preselected adapted solvent. main goal study recover undamaged in order reuse them as reinforcements “second-generation” composites. Two protocols were compared. first one is based on an ultrasound technique, second mechanical stirring....
The aim of this work was an investigation the ability gallic (GA) and ellagic (EA) acids, which are phenolic compounds encountered in various plants, to act as flame retardants (FRs) for epoxy resins. In order improve their fireproofing properties, GA EA were treated with boric acid (to obtain derivatives (GAD) (EAD)) introduce borate ester moieties. Thermogravimetric analysis (TGA) highlighted good charring EA, enhanced by boration. grafting groups also shown increase thermal stability that...
In view of their use as source material for new biobased flame retardants, chestnut wood extracts were prepared using different solvent systems and compared to an industrial extract. The mainly composed hydrolyzed products ellagitannins (castalin, vescalin, ellagic acid) along with saccharides. proportions components strongly depended on the system used extraction. Water-based solvents promoted recovery (up 15 wt % dry raw matter), while alcohol-based extracted more selectively acid 47...
