Abstract: The present disclosure provides a stimuli responsive nanocomposite for selective adsorption, retention and controlled release of target chemical species. The nanocomposite consists of functionalised nanostructured adsorbents dispersed in the responsive polymeric, hydrogel-based porous or hybrid matrix. The adsorbents provide target-selective binding sites and the matrix undergoes a reversible physicochemical change in response to temperature, pH, light, humidity, ionic strength, electric fields, magnetic fields, chemical signals or combinations thereof. Under a first condition, the target species diffuse through the matrix and are captured by the functionalised adsorption sites. A pre-defined stimulus triggers regulated desorption and release through changes in porosity, permeability, surface charge, molecular conformation or binding affinity. The nanocomposite can be in the form of particles, beads, membranes, films, fibres, coatings, capsules, scaffolds or monoliths. The nanocomposite disclosed herein provides improved adsorption capacity, selectivity, stability, recoverability, reduced premature desorption and repeatable regeneration for environmental remediation, chemical separation, resource recovery, sensing, catalysis and controlled-delivery applications.
