AFM picture of the nanoparticle sample functionalized with MHDA showing different sizes of agglomerated particles.
A comparison between (a) the topographical picture and (b) the phase picture for the sample containing MHDA functionalized particle illustrating that covered or exposed particles can be distinguished in the phase picture.
The liquid crystal with an APTS functionalized particle, showing different sizes and exposed particles.
The drawing illustrates how the liquid crystal molecules cover the particles when (a) the functionalization forces the molecules to align perpendicular to the particles; (b) the functionalization forces the liquid crystal molecules to align parallel to the particles. The first half layer (see Ref. 20) is not shown for clarity.
Size ranges of covered and uncovered nanoparticles for the MHDA and APTS functionalized nanoparticles compared to Roiter’s uncovered nanoparticle.
