Research by Kuutti (2013) demonstrated that controlled solution precipitation of starch polymers can yield spherical particles with diameters around 0.5 µm, suitable for enhancing paper coating applications. This method leverages the spontaneous self-assembly of solvated starch chains upon introduction of a non-solvent, offering a pathway to engineer particle morphology for improved material performance and affinity to substrates.
