Porefree
Porefree (often written as pore-free or porefree) is a descriptor used in materials science to denote materials or surfaces with negligible porosity. A porefree material has a density approaching the theoretical maximum and contains few, if any, interconnected voids that would permit fluid or gas transport. The term is typically applied to dense ceramics, metals, polymers, and coatings where impermeability and barrier properties are essential.
Key properties of porefree materials include high density, very low permeability to liquids and gases, and
Producing porefree materials involves techniques aimed at eliminating or sealing voids. In metals and ceramics, processes
Applications of porefree materials occur where impermeability and strength are critical. Examples include aerospace components and
Measurement and verification of porefreeness rely on density assessments, porosimetry, X-ray computed tomography, and surface or
