Abstract Developing superwetting coatings with environmental adaptability is critical for sustainable industrial applications. However, traditional anti‐wetting often fall short due to their susceptibility factors (UV light, temperature, mold growth, and abrasion) inadequate stain resistance in complex media. Herein, a durable ex situ pH‐responsive coating reversible wettability switching, engineered by integrating hydrophobic polydimethylsiloxane tertiary amine structures presented. The resulting hierarchical micro‐nano surface structure, combined trapped air cushion, ensures low water adhesion stable superhydrophobicity. Notably, after pH treatment, the modulation of N + content synergistically interacts chains, enabling controlled transition from 150° 68.5°, which can spontaneously revert state upon heating drying. This enhances both underwater environments, 17.2% increase detergency compared superhydrophobic controls. Moreover, demonstrates remarkable durability, no staining, peeling, or mildew growth (grade 0) even 1500 h UV radiation 28 days testing. work offers highly adaptable stain‐resistant applications building infrastructure protection, as well smart textiles designed multi‐media decontamination.

A knitted aryl network polymer (KAP) containing triptycene and triphenylphosphine was synthesized by a simple Friedel–Crafts reaction. The (Tp_PPh3) exhibits good physicochemical stability with high BET surface area (>960 m2/g). groups were incorporated in order to anchor palladium species on the pristine KAP backbone (Tp_PPh3). Consequently, metalation of Tp_PPh3 yielded Pd@Tp_PPh3, which showed catalytic behavior Suzuki–Miyaura cross-coupling reactions yield targeted products an aerobic environment, using water ethanol as green solvents. This polymer-based heterogeneous catalyst is air/moisture stable can be easily dispersed reused for several cycles without any significant loss activity. Even at low loadings (13.8 wt %), Pd@Tp_PPh3 catalyzed rapid conversions. equally useful gram-scale reactions. strategy avoids aggregation precipitation Pd simultaneously ensures more sustainable use Suzuki application may extended other Pd-catalyzed
