In order to study the adhesion properties of fast-melting SBS-modified asphalt (SBS-T) at the interface with aggregates, the contact angles of three dosages of SBS-T asphalt with three liquids (distilled water, glycerol, and formamide) were determined by the sessile drop method based on surface free energy theory. The evaluation indexes such as cohesion, asphalt-aggregate adhesion, stripping work and energy ratio of the asphalt were analyzed and the adhesion properties of the asphalt-aggregate system were investigated with the help of micromechanical methods. The results indicate that SBS-T can improve the adhesion properties of the asphalt. Furthermore, as the dosage of the modifier increases, the cohesion work, adhesion work, and energy ratio of the SBS-T asphalt exhibit a similar rise. As the spalling work reduces and the adhesion between asphalt and aggregate improves, it is noteworthy that the SBS-T asphalt-aggregate system exhibits superior adhesion performance compared to the SBS-modified asphalt-aggregate system, despite the same dosage.

We report a controlled deposition process using atmospheric plasma to fabricate silver nanoparticle (AgNP) structures on polydimethylsiloxane (PDMS) substrates, essential for stretchable electronic circuits in wearable devices. This technique ensures precise printing of conductive structures using nanoparticles as precursors, while the relationship between crystallinity and plasma treatment is established through X-ray diffraction (XRD) analysis. The XRD studies provide insights into the effects of plasma parameters on the structural integrity and adhesion of AgNP patterns, enhancing our understanding of substrate stretchability and bendability.

Polylactic acid (PLA) composites with high straw content face several challenges, primarily due to the inherent brittleness of straw and its poor compatibility with the polymer matrix. In this study, scanning electron microscopy (SEM) was used to analyze the microscopic structure of wheat straw chemically modified by NaOH and the silane coupling agent, and it was concluded that both treatments effectively removed waxes and silica from the surface of the straw, enhanced fiber roughness, and improved interfacial adhesion. Notably, the silane coupling agent treatment not only facilitated the formation of chemical bonds between the straw fibers and the PLA matrix but also filled the interfiber pores, significantly increasing the structural density.

Despite the advances in the development of therapeutic wearable wound-healing patches, lack self-healing properties and strong adhesion to diabetic skin, hindering their effectiveness. We propose a unique, wearable patch made from a 3D organo-hydrogel nanocomposite containing polydopamine, titanium dioxide nanoparticles, and silver quantum dots (PDA-TiO@Ag). The designed patch exhibits ultra-stretchable, exceptional-self-healing, self-adhesive, ensuring conformal contact with the skin even during movement.
