Influence of the Species of Mold Fungi and the Roughness of Varnished Cambric on Their Adhesive Interaction

The influence of the species affiliation of mold spores and the surface roughness of varnished cloth on the process of their adhesive interaction is studied. The possibility of carrying out an assessment using a quantitative parameter of the process, i.e., the maximum number of spore adhesion to polymeric materials, is shown. The obtained values of the adhesion parameters are compared with the spore radii and surface roughness, which is characterized by the distance between the tops of its irregularities. It is established that on a smooth surface the adhesion parameter increases with increasing radius. On a rough surface, it can both decrease and increase. The results should be taken into account when developing methods for the rapid assessment and prediction of the resistance of materials to infection with spores of biodestructor fungi.
