“…The suitable size matching might lead to alumina NPs filling in the interspace between the packed superhydrophobic particles according to the particle packing theory, which increases the hard particle packing efficiency and facilitates adhesiveness between solid particles and resin. [30,31] Apart from sandpaper abrasion, particle collision cannot be ignored when assessing the durability of the coatings. [32] Here, the sand impact was carried out to evaluate the tolerance of the fabricated coatings to normal impacts.…”

The development of materials that repel water, known as superhydrophobic materials, has been hindered by their vulnerability to mechanical abrasion. This issue is particularly pronounced for superhydrophobic nanocomposite coatings fabricated using a simple blend of resin and nanoparticles through uncomplicated methods such as spraying or brushing, where an excessive amount of nanoparticles can deteriorate the mechanical property. Moreover, the limitation of thickness put forward a request of a high retention rate of the coatings. In response to these challenges, this study presents an innovative approach aimed at enhancing the robustness of superhydrophobic nanocomposite coatings through the utilization of a straightforward dual spraying technique. The results demonstrated that the particles with hierarchical micro/nanostructures fabricated by the primary spraying process provided abundant roughness feedstocks for the secondary‐sprayed coatings, in which superhydrophobicity properties could be achieved with less nanoparticle content. Additionally, the mechanical durability of the coatings can be reinforced by the addition of appropriate amounts of aluminum oxide (Al2O3) nanoparticles and the continuous‐distributed particles fabricated by the primary‐spraying process, exhibiting a longer abrasion distance and a higher retention rate. Also, the prepared sample shows comprehensive robustness in adhesion, abrasion and dynamic impact tests. By offering insights into material selection and process optimization, this study paves the way for creating resilient superhydrophobic coatings using a streamlined and convenient approach.This article is protected by copyright.

“…[13,14] Self-healing is one of the repair techniques that has been proposed to address this issue. [15][16][17] However, these approaches are not applicable for chemically impaired or compressed aerogels. Apart from recycling and repairing, the capacity to precisely adjust or reprogram the properties of aerogels is also highly appealing.…”

With rising energy demands and costs, the significance of thermally insulating materials is on a constant upward trajectory. While they offer impressive performance, their sustainability is increasingly becoming an essential design feature. The study thus develops an unprecedented strategy that enables recycling, repairing, and reprogramming of superinsulating polyimine aerogels. The principle at play involves the decomposition of polyimine aerogels into a solution of oligomers through transimination reactions with additional amines. This solution can be utilized to create new aerogels with virtually identical properties to the original ones. This aerogel‐to‐sol‐to‐aerogel (ASA) process is also applicable to mixed waste streams and damaged aerogels. Moreover, this method allows to alter the aerogel properties post‐synthetically through careful selection of amines. Since the ASA process is highly reproducible and selective, omits purification steps, and conserves 100% of the initially embedded chemical resources, it presents an innovative tool for the sustainable management of superinsulating aerogels.
