Polymer particles in the submicrometer size range arouse interest in the field of materials science. This is primarily due to the versatility of properties that can be easily adapted to polymer microbeads. Polymer microbeads are easily synthesized from a variety of materials and the surface charge of the particles is easily functionalized using either during synthesis or post-synthesis modification. There are a number of techniques that yield particles of a predetermined size and a very narrow size distribution.
Generally, the polymer particles have spherical shapes. However, other conventional shapes can be produced by thermodynamic and kinetic methods. Using these methods, core-shell and multilayer particles are easily produced. In macroscopic polymer-based materials, polymer microbeads offer an additional scale of length determined by the particle diameter. Thus, polymer particles are used as building blocks of materials with periodic composition, structure and function.
Polymer particles in the size range from about 100 nm to 1 µm are temporarily separated into latexes and microgels. Latex particles have a dense structure while microgels have an open polymer network structure. At appropriate pH values and suitable solvents, latex beads swell and turn into microgel particles. Thanks to the open structure of the microgels, with this application, the polymer network separates and releases small molecules or nanoparticles or changes its volume in response to external stimuli such as pH value, temperature or ionic strength.
Polymer particle sizes are determined in advanced laboratories by automated optical or electron microscopy or laser scattering. These analyzes are performed wet or dry. In the analysis, image acquisition and particle detection methods are applied, large particles are detected automatically and bubbles are detected automatically. The result is a real-time trend graph and histogram with simultaneous circular diameter. This histogram uses optional advanced software and includes shape distribution, ie aspect ratio, roundness, length and width values.
