adhesieve

Adhesieve refers to a conceptual class of materials that combine adhesive properties with porous, sieve-like structure, enabling simultaneous adhesion to substrates and selective molecular transport or capture. In this framework, an adhesieve material can bond to a surface while presenting a network of pores or channels that permit the passage or binding of target species based on size, shape, or chemical affinity.

Design and mechanisms: The functional porosity can be created by templating, phase separation, or grafting porous inorganic or polymer domains into an adhesive matrix. Alternatively, porous substrates can be coated with adhesive layers that preserve porosity and introduce surface functional groups to achieve selective interactions.

Applications: Potential uses include filtration membranes that adhere to industrial surfaces, catalyst supports that anchor reagents while allowing diffusion, wound dressings that adhere to tissue yet permit fluid exchange, and composite laminates where interfacial bonding and porosity aid interlayer communication.

Advantages and limitations: By combining adhesion and porosity, adhesieve materials can simplify assemblies and enable multifunctionality, but balancing adhesive strength with pore connectivity can be challenging; curing processes may block pores; long-term stability and scalability are concerns.
