Pollen from species such as cedar and ragweed can neg. affect human health, and this is a problem around the world. Various attempts were made to mitigate the effects of pollen on human health. This study was focused on removing pollen from air by efficiently collecting the pollen. To achieve that requires the phys. properties of the pollen surfaces to be understood. Hansen solubility parameters (HSPs) are useful for evaluating the surfaces of particles made of materials such as ZrO2, TiO2, and SiO2. However, it is difficult to evaluate the surfaces of particles made of biomaterials (e.g., pollen and mite and flea carcasses) because of the complex surface structures of such particles. In this paper, HSPs for pollen particle surfaces were measured using the capillary permeation method, which can be used to evaluate even particles with complicated shapes. The chem. structures of the pollen surfaces were then investigated to provide data to validate the measured HSPs. The measured cedar pollen HSPs were (δd, δp, δh) = (15.8, 5.4, 11.7), and the measured cypress pollen HSPs were (δd, δp, δh) = (16.0, 4.7, 11.3). A liquid mixture designed to be compatible with the HSPs was also developed.
