    Abstract: Polyethylenimine (PEI) is a cationic polymer widely used in non-viral gene delivery systems and other polymer technologies. PEI with a MW of 25 kD was cross-linked in aqueous solution by the aromatic di-aldehyde isophthalaldehyde. This di-aldehyde cross-links PEI by forming stable imines with the primary amine groups in branched PEI. Cross-linking ... Show More

    Abstract: Polymers contain extraordinary qualities, such as self-healing. Research and development of this form of polymer, which regenerates after injury, is an essential asset for artificial material lifetime and environmental sustainability. These polymers produced through polar interactions, hydrogen bonds, disulfide bonds, Diels Alders reactions and oth... Show More

    Abstract: Natural fiber-reinforced nanocomposites (NFRCs) are proved as the best alternative for synthetic composites in view of cost and environmental effects. NFRCs have been produced from agro-waste such as banana tree fiber (BFs), because BF are strong, light-weight, and have smaller elongation. To improve the quality of BF, multiwall carbon nanotubes (M... Show More
