Polyethylenimine (PEI) or polyaziridine is a polymer with repeating units composed of the amine group and two carbon aliphatic CH2CH2 spacers. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. Totally … See more The linear PEI is a semi-crystalline solid at room temperature while branched PEI is a fully amorphous polymer existing as a liquid at all molecular weights. Linear polyethyleneimine is soluble in hot water, at low pH, in See more Branched PEI can be synthesized by the ring opening polymerization of aziridine. Depending on the reaction conditions different degree of branching can be achieved. Linear PEI is available by post-modification of other polymers like poly(2-oxazolines) or N … See more Polyethyleneimine finds many applications in products like: detergents, adhesives, water treatment agents and cosmetics. Owing to its ability … See more • Tetraethylenepentamine • Ethylenediamine • Polyetherimide (Also goes by PEI) See more WebDec 12, 2024 · X-ray diffraction (XRD) was performed to obtain the crystalline structure of the synthesized nanoparticles. The XRD pattern for PEI functionalized iron oxide nanoparticles is given in figure 2 . The six characteristic peaks for Fe 3 O 4 at 2 θ = 30.1 ° , 35.5 ° , 43.1 ° , 53.4 ° , 57.0 ° and 62.6 ° indicated that the synthesized particles are Fe 3 O …
