Summary: In this article, the tensile modulus of a polymeric system containing dispersed halloysite nanotubes (HNT) and adjacent interphase section is investigated using the Kolarik model. The model considers factors such as HNT concentration, the extents of HNT and nearby interphase section, and the densities of polymer medium and HNT. The results show that the modulus of the system decreases with increasing HNT radius, while HNT weight percentage directly controls the nanocomposite's modulus. Furthermore, the experimental data matches the calculations, validating the accuracy of the model.

Summary: In the field of cultural heritage conservation, traditional products have been widely used for the plastic reintegration of wooden artifacts, although not specifically designed for this purpose. This study explores the use of cellulose pulp, obtained from softwood almond shells, as the most suitable material for wood restoration due to its material compatibility and potential for waste reuse. The cellulose pulp was combined with different binders to manufacture stuccos for wood consolidants, and also combined with the essential oil of Thymus capitaus to create stuccos with biocidal properties against fungal colonization or insect infestation. The physical flexion properties of the new materials were tested.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
