tinypore

Tinypore is a descriptor used in materials science to refer to pores on the micron- to nanometer-scale that are incorporated into membranes, filters, catalysts, and related materials. It is not a single material but a class of pore structures defined by size, shape, and distribution. The term emphasizes the small dimensions of the pores and their role in controlling transport.

Size and morphology: Tinypores typically range from a few nanometers up to about one micrometer in diameter. Pore shapes can be cylindrical, conical, or irregular, and their architecture can be highly tortuous depending on fabrication. The pore volume and surface area are critical design parameters affecting performance.

Fabrication: Tinypores are produced by templating methods (hard templates like silica spheres, soft templates like block copolymers), etching techniques (chemical or reactive ion etching), or self-assembly routes. Post-synthesis treatments such as pore widening or deposition of functional coatings adjust selectivity and stability. Materials include polymers, silica, carbon, and metal oxides.

Applications: They are used in water and gas separation, nanofiltration, biosensing, catalysis, energy storage membranes, and microfluidic devices. The ability to tailor pore size distribution enables selective transport of small molecules while rejecting larger ones.

Research and economics: Tinypore structures are an active area in academia and industry, with focus on scalable fabrication, fouling resistance, and integration into commercial membranes. The term appears in scientific literature as a descriptive category rather than a brand name.
