Sustainable Polymers Derived From Naturally Occurring Materials
Nearly 95% of monomers or chemical intermediates used today are based on fossilized carbon such as coal and petroleum. This has resulted in a high rate of depletion of fossilized reserves, continuous escalation in petroleum prices, environmental impact with the increase in emission of greenhouse gases, and accumulation of non-biodegradable waste on earth. Current global main challenges are movi...
متن کاملNanocomposites Derived from Polymers and Inorganic Nanoparticles
Polymers are considered to be good hosting matrices for composite materials because they can easily be tailored to yield a variety of bulk physical properties. Moreover, organic polymers generally have long-term stability and good processability. Inorganic nanoparticles possess outstanding optical, catalytic, electronic and magnetic properties, which are significantly different their bulk state...
متن کاملRenewable co‐polymers derived from castor oil and limonene*
Biobased monomers derived from castor oil as well as from limonene suitable for thiol–ene copolymerization were synthesized. Di‐10‐undecenylether 2 was obtained via GaBr3‐catalyzed reduction of 10‐undecenyl 10‐undecenoate 1. Diene ether 2 and (R)‐limonene 5 were reacted in two steps using radical thiol–ene addition reactions to dithiol ether 4 and dithiol 7, respectively. Diene ether 2 and dith...
متن کاملRobust antimicrobial compounds and polymers derived from natural resin acids.
We report novel robust resin acid-derived antimicrobial agents that exhibit excellent antimicrobial activities against a broad spectrum of bacteria (6 Gram-positive and 7 Gram-negative) with selective lysis of microbial membranes over mammalian membranes. Our results indicate that hydrophobicity and unique structures of resin acids can be determining factors in dictating the antimicrobial activ...
متن کاملAntimicrobial Activity of Some Schiff Bases Derived from Benzoin, Salicylaldehyde, Aminophenol and 2,4 Dinitrophenyl Hydrazine
The antibacterial and antifungal activities of three schiff bases were evaluated against some pathogenic bacteria and fungi. Parallel experiments were also carried out with standard drugs (Kanamycin for bacteria and Nystatin for fungi). Two compounds [N-(1-phenyl-2-hydroxy-2phenylethylidine)-2',4' dinitrophenyl hydrazine, abbreviated as PDH and N-(2-hydroxy benzylidine)-2'-hydroxy imine, abbrev...
