“…Figure 6 (a), (b), and (c) show that each material had light-trapping structures in the form of crack gaps, pores, and rough surfaces. Several studies have confirmed that holes [54], rough surfaces [55], and pores [56] can improve the light absorbance of photothermal absorbers. Figure 6 also shows that there were crack gaps in the materials, which can be classified as light-trapping structures.…”

The development of cost-effective and environmentally friendly solar thermal technologies that deliver high performance poses several challenges, where the collector and absorber components play a pivotal role. This research addresses these issues by investigating enhanced temperature generation using a 30 cm × 30 cm Fresnel lens collector under solar illumination from a xenon lamp. Natural stone materials (andesite, coal, and pumice), characterized by granular structures with an average diameter of 1.68–2.00 mm, were selected because of their abundance and eco-friendliness. This research is focused on evaluating the effect of Fresnel lens on temperature generation performance. Two types of temperature generation tests were carried out: wet tests (where the natural stone materials were immersed in distilled water) and dry tests (where the natural stone materials were used in dry conditions). The morphologies of the natural stone materials were examined using an optical microscope and scanning electron microscope. Furthermore, the optical properties of the natural stone materials were analyzed using an ultraviolet–visible (UV–VIS) spectrophotometer. The findings revealed that there were significant improvements in the photothermal absorber performance with the use of a Fresnel lens in dry tests, where the highest temperature was achieved for coal (103.25 °C), followed by andesite (89.00 °C) and pumice (73.00 °C). The impurities varied between the materials, where the impurities were most dominant for pumice while coal was more uniform. Further examination using scanning electron microscope showed that all materials had light-trapping structures in the form of rough surfaces, pores, and crack gaps. Andesite was dominated by rough surfaces, while coal and pumice were dominated by crack gaps and pores, respectively. However, based on the UV–VIS spectrophotometric results, there were no correlations between the optical properties (absorbance, reflectance, and transmittance) and temperature achieved by the photothermal absorber materials. This research demonstrates the potential of using natural stone materials as photothermal absorbers in combination with a Fresnel lens collector for low-to-medium temperature solar thermal applications.

Nano‐injection molding technology is an important method for large‐scale production of metal‐polymer composites of various shapes. The mechanical properties of these materials are closely related to the interfacial process. In this work, polyphenylene sulfide (PPS) and copper (Cu) were selected as candidate polymer and metal materials, and constructed four different polydopamine (PDA) coatings, including monomer, dimer, linear tetramer, and cyclic tetramer, to modify metal surfaces. The molecular dynamics simulations were launched to investigate the interaction behavior of heterogeneous interfaces during nano‐injection molding and the mechanism by which polydopamine affects the adhesion behavior at the copper‐polyphenylene sulfide interface. Results showed that the addition of polydopamine caused the polymer chains to form many anchor points on the contact surface, which inhibited the wall‐slip behavior of the polymer and led to a mushroom‐like movement of the polymer on the wall surface. The interfacial energy, filling rate data revealed that polydopamine contributes to the enhancement of interfacial adhesion properties, and the polydopamine dimer structure is the most effective of the four configurations. The enhancement of interfacial adhesion mainly originates from the enhancement of non‐bonding interactions and entanglement anchoring between PPS‐PDA.Highlights Polydopamine coating inhibits polymer slip behavior in nano‐injection molding. Polydopamine enhances bond strength of metal‐polymer composites effectively. Dopamine dimers have better adhesion properties than other structural dopamine. Polydopamine coating alters the adhesion mechanism at heterogeneous interfaces. The interface failure mode was closely related to the stress loading mode.
