Secondary reactions induced by functional surface coating are of critical significance and have attracted substantial interest, as the can function a versatile platform for designing multifunctional coatings tailoring performance. The incorporated tannic acid, 3-aminopropyltriethoxysilane (TA-APTES) contains plentiful nanospheres with secondary reaction sites, which is favorable modification. In this research, TA-APTES unique hierarchical structure was grown in situ on skeleton porous melamine sponge under mild conditions. triggered were comprehensively employed to construct various applications. TA-APTES-coated first immersed silver ammonia solutions reduction ions. decoration Ag NPs endowed catalytic antibacterial activity, could be applied dye bacterial disinfection wastewater. energy subsequently decreased long-chain alkyl molecules. After condensation polymerization octadecyltrimethoxysilane, coated converted into superhydrophobic state, making it suitable efficient separation oil water mixtures. prepared demonstrated remarkable repellency strong affinity contact angle 156.5° 0°. Significantly, retained relatively stable absorption capacity efficiency after multiple recycling utilization. proposed routine fabrication design demonstrates potential develop solving pollution issues.
