PEI coated Fe3O4 nanoparticlesProduct Name Name: a>PEI coated Fe3O4 nanoparticles Product Overview Magnetic Fe3O4 nanoparticles modified with polyethyleneimine (PEI) are a composite nanomaterial that combines the characteristics of magnetic nanoparticles and polyethyleneimine. Polyethyleneimine is a highly branched polymer with a high density of amino groups. These amino groups can stabilize Fe3O4 nanoparticles and provide further functional modification sites. The amino group of

it has good conductivity

fuel cells

and low-temperature curing

Because of their special orientation

Tap density: 0

2) Repeated freezing and thawing should be avoided during the use and storage of beads

and this pore structure gives it good selectivity

even exhibiting certain conductivity under certain conditions

Light emitting devices: Used as a light emitting layer or auxiliary layer in LEDs to improve device performance

for early diagnosis of tumors

Rutile and anatase belong to the tetragonal crystal system

their local surface plasmon resonance (LSPR) can be adjusted
