Design, characterization and applications of nanocolloidal hydrogels

“…2, left panel)) include carbon-based NPs such as graphene carbon dots 50 or silane functionalized carbon dots, 51 metal oxide NPs, e.g., TiO 2 52 or Co-dopped Fe 3 O 4 , 53 non-metal oxide, e.g., SiO 2 , 54,55 semiconductor NP such as perovskite nanocrystals CsPbBr 3 , 56 and noble metal NPs such as Au 57,58 or Ag NPs. 38 Organic NPs can be assembled from synthetic polymers or synthesized, e.g., poly(N-isopropylacrylamide) (pNIPAm) 59 or polystyrene, 60 NPs respectively. These NPs are represented by e.g., latexes 6 or nanogels.…”

Electrostatic Heteroaggregation: Fundamentals and Applications in Interfacial Engineering

“…In spite of the enormous potential, the principles of heteroaggregation have not been adequately utilized, especially in porous material development. Nonetheless, some studies have focused on the fabrication of highly macroporous ceramic using a heteroaggregation-based dispersion processing route. , Another approach to producing porous materials is by using gels formed by exploiting heteroaggregation. , We have introduced a new processing method which involves the incorporation of oil drops into colloidal gels formed via the electrostatic heteroaggregation of particles that enables the development of ceramics with pores in the 20–60 μm size range . The porous material is obtained by the removal of oil drops and water trapped in the particle network via controlled drying followed by sintering.…”

Controlled Sequential Assembly of Metal–Organic Polyhedra into Colloidal Gels with High Chemical Complexity

“…To tackle these issues, one can consider using a colloidal gel system, in which chemically different mesoscale colloidal particles can be interconnected through electrostatic interaction [21] or chemical bonding [22][23][24][25] to form multicomponent colloidal networks. Interestingly, depending on the interaction between particles, the assembled structures of two chemically distinct colloids can either 1) be self-sorted into a network and form double interpenetrated colloidal networks, or 2) be led to the preferential interaction between two different colloids (e.g., electrostatic interaction) yielding to the formation of a mixed colloidal network.…”
