Drawing inspiration from the secretory tissues in plant bodies, here we present a facile strategy to prepare a stimuli-responsive organohydrogel with water-driven and thermally-driven oil-release functions, and the responsive wettability is achieved. In essence, the stimuli-responsive secretory function is inextricably linked to the infiltration and exfiltration behavior of different dispersion media between heterogeneous networks. The responsive deswelling of the dispersion medium can be induced by certain environmental factors, including changing the dispersion medium or environmental temperature, which further enables unique on-demand water-driven and thermally-driven oil-release properties. It is anticipated that such smart, self-secreting organohydrogel materials, featured with controllable liquid loading and releasing properties, have great potential in a variety of fields, such as drug delivery systems, self-lubrication and antifouling surfaces, and controlled embedding and release of bioactive molecules.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"719 ","pages":"Article 136982"},"PeriodicalIF":4.9,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the optimal dosages of CTAB and CPAM were 0.8 kg/t and 30 g/t, respectively. CTAB reduced the surface tension of the filtrate to 30.75 mN/m, while it increased the hydrophobic functional groups on the coal surface and the free water content in the filter cake 5.39 % and 7.17 %, respectively. Thus, CTAB increased the hydrophobicity of the pore walls and the flowability of the filtrate, and reduced the moisture binding of the pores. This promoted the moisture migration and caused part of the non-flowable capillary water in the filter cake to be transformed into flowable free water. However, CPAM reduced the absolute value of Zeta potential by 20.20 mV, decreasing the electrostatic repulsion between coal particles. Meanwhile, CPAM increased the floc size to 20–60 μm, which promoted floc formation and improved the pore structure, increasing the filter cake porosity by 5.19 %.

This synergistic approach enabled a controlled high-density distribution of Schiff base groups and functional adsorption sites (hydroxyl/mercapto/amino) within the UiO-66 framework in order to obtain HD-UiO-66-AHB/AMB/DB. Characterization techniques confirmed the successful integration of multiple active sites and uniform ligand distribution, which established a synergistic adsorption network that significantly enhanced heavy metal adsorption performance.

All adsorption processes followed pseudo second-order kinetics and the Langmuir model. Furthermore, the coordination of heavy metal ions with the nitrogen atoms in the bis-Schiff base and the doped O/S/N atoms forms bidentate and tridentate complexes, endowing the material with a highly selective adsorption capability for target metal ions under the coexistence conditions of ten coexisting cations.
