General description
微粒或乳胶珠，通常称为聚苯乙烯微粒，是带负电的胶体颗粒。微粒是通过苯乙烯在受控条件下的聚合反应制备的。反应的有利环境诱导自发聚结珠的形成。微粒或乳胶珠以由聚合物颗粒与水组成的水溶液提供。聚苯乙烯′在 589 nm 处的折射率为 1.5905，在 486 nm 处为 1.602。

Hollow silica and silica-polymer spheres with diameters between 720 and 1000 nanometers were fabricated by consecutively assembling silica nanoparticles and polymer onto colloids and subsequently removing the templated colloid either by calcination or decomposition upon exposure to solvents.

The unusual properties of nanocomposites are commonly explained by the structure of their interphase. Therefore, these nanoscale interphase regions need to be precisely characterized; however, the existing high resolution experimental methods have not been reliably adapted to this purpose. Electrostatic
