- Abstract
- Glycidyl-functional polymer nanoparticles [poly(glycidyl methacrylate)
(PGMA)] were fabricated with microemulsion polymerization. The successful fabrication
of PGMA nanoparticles was confirmed by Fourier transform infrared spectroscopy
and transmission electron microscopy (TEM). A TEM image showed that the
average diameter of the PGMA nanoparticles was approximately 10–28 nm and was
fairly monodisperse. As the surfactant concentration increased, the average size of
the nanoparticles decreased and approached an asymptotic value. A significant reduction
of the nanoparticle size to the nanometer scale led to an enhanced number of
surface functionalities, which played an important role in the curing reaction. The
PGMA nanoparticles were cured with a low-temperature curing agent, diethylene
triamine, to produce ultrafine thermoset nanoparticles. The low-temperature curing
process was performed below the glass-transition temperature of PGMA to prevent
the coagulation and deformation of the nanoparticles. A TEM image indicated that
the cured PGMA nanoparticles did not exhibit interparticle aggregation and morphological
transformation during curing. The average size of the cured PGMA nanoparticles
was consistent with that of the pristine PGMA nanoparticles
