Plasmachemical Amine Functionalization of Porous Polystyrene Spheres:  The Importance of Particle Size

Allylamine plasma functionalization of porous polystyrene spheres is found to depend on particle size. A combination of Fmoc derivatization and cross-sectional Raman microscopy has shown that an outer layer of approximately 3−4 μm can be selectively functionalized to yield relatively high amine grou...

Beschreibung
Zusammenfassung:Allylamine plasma functionalization of porous polystyrene spheres is found to depend on particle size. A combination of Fmoc derivatization and cross-sectional Raman microscopy has shown that an outer layer of approximately 3−4 μm can be selectively functionalized to yield relatively high amine group loadings.
