Polymer nanoparticles (PNPs) were formed from amphiphilic diblock
copolymers consisting of a hydrophilic block with pendant polyethylene
glycol tosylate (PEG-OTs) groups and a hydrophobic block with pendant
terthiophene (TTT) groups. The resulting PNPs were characterized
using dynamic light scattering (DLS) and transmission electron
microscopy (TEM) to determine size, shape, and...
The formation of covalently grafted polymer brushes on silica (SiO2)
nanoparticles was achieved by surface-initiated reversible additionfragmentation
chain transfer (si-RAFT) polymerization. RAFT initiator
was first attached onto the surface of silica nanoparticles and then
examined by ultraviolet-visible spectroscopy (UV-vis) analysis. From the
resulting RAFT initiator-modified SiO2 nanoparticles, polymer chains
can...
