Chitosan-based biopolyelectrolyte composites intercalated montmorillonite : A strategy for green fire retardent and mechanical reinforcement of polypropylene composites.Due to dwindling oil resources and the need for environmental security , the development of bio-based fire retardents has incured much attention . In order to search the feasibleness of full biomass polyelectrolyte complexes ( PEC ) for polyolefin fire retardant applications , chitosan ( CS ) , sodium alginate ( SA ) , and Na phytate ( SP ) were used to train CS-based fully biomass PEC intercalated montmorillonite ( MMT ) hybrid biomaterials ( SA-CS @ MMT and SP-CS @ MMT ) . The effects of two hybrid biomaterials on the fire refuge and mechanical props of tumescent flameproof polypropylene ( PP ) composites were equated . The SP-CS @ MMT showed the best flaming retardancy and toughening upshot at the same addition sum . After appending 5 wt % SP-CS @ MMT , the specifying oxygen indicant ( LOI ) value of PP5 handed 30 % , and the peak heat release rate ( pHRR ) lessened from 1348 kW/m ( 2 ) to 163 kW/m ( 2 ) .
In addition , the H bonding between polyelectrolyte composites importantly amended the mechanical attributes of PP composites . Compared with PP2 , the ductile effectiveness of PP5 increased by 59 % . This field offered an efficient and eco-friendly strategy for the large-scale yield of renewable biomaterials with good caloric stability and expanded the coating of macromolecular biomaterials in the field of fire safety.New approach for working chitosan as low cost protective intercrossed coating for C-steel in acid media.The knickknack of this cogitation is that it the first time blend and formulation of chitosan as a new hybrid ( organometallic ) protective finishings for achieving synergistic auspex for carbon steel alloy during acid pickling . The role of coated silica ( by 0 wt % stearic acid lubricant ) in the advance of surfacing functioning was highlighted . Variable weight percentage of chitosan and silica in addition to a frozen weight percentage ( 35 % ) of guar gum instinctive plant rosin , 5 × 10 ( -6 ) mmol ( 2-Hydrazinyl-6-methyl ( or phenyl ) -4 , 5-di-H pyrimidinone ) as organic corrosion inhibitors were compounding as hot melt in the front of a low cost wetter as an emulsifying broker ameliorated compatibility between coating constituents .
Guar gum increased coating flow during application and ingrafted chitosan into high molecular copolymer resin indissoluble in acid media . Phosphorous acid improved coating flexibility during application by hot dipping . Hybrid caking decreased corrosion potential of C brand and retarded both redox reactions of corrosion moving as adsorbed mixed-type inhibitor . shares security ( % P ) approached 100 percentage as corroborated from the arrangement between impedance and polarization parameters . Guar gum plant resin and slice powder increased gloss of caking . The coated silica fulfiled the stomates and increased stiffness of caking . Super hydrophobicity of covering was affirmed by the quantified striking angle above 150 ( o ) C indicating good spreading of coating sample as isolating adherent aerofoil film .
Functional belongings and molecular dockage of unlike nanoparticles with ROS-sensitive phenylboronylated chitosan as the carrier.OBJECTIVE : To train chitosan-loaded nanoparticles ( NPs ) that enhance the oral bioavailability of puerarin ( Pur ) and render it responsive to reactive O species ( ROS ) This inquiry makes satisfying advancement towards the hypothesis of intelligent drug delivery , proffering a new reference for combining Pur with former natural medicinal active components The acylation reaction between chitosan and ROS-sensitive 3-carboxyphenylboronic acid ( PBA ) was used to synthesize ROS-sensitive phenylboronylated chitosan ( PBACS ) PBACS-PBA-Pur-NPs and PBACS-TPP-Pur-NPs were inclined via ion gelation after the addition of PBA and Na tripolyphosphate ( TPP ) , severally . The physicochemical and functional properties of both NPs were compared , and their disputes were preliminarily analysed through molecular bobing Reactive O species-sensitive PBACS was successfully synthesized .
