Preparation of Porous Poly(ɛ-caprolactone) Structures
Macromolecular Rapid Communications, 2002Porous poly(ε-caprolactone) structures have been prepared by leaching of compression moulded salt-containing polymer precipitates. Coagulation takes place when a PCL solution containing dispersed water-soluble salt particles is precipitated into an excess of non-solvent.

Monodisperse porous polymer particles: Formation of the porous structure
Journal of Polymer Science Part A: Polymer Chemistry, 1992AbstractMonodisperse porous styrene‐divinylbenzene copolymer particles were prepared via seeded emulsion polymerization using a mixture of linear polymer (polystyrene seed) and non‐solvent as inert diluent. Experimental evidence was presented to describe the mechanism of formation of porous polymer particles during the copolymerization and solvent ...

Pore size and pore size distribution are defined, 1-D pore structure models are reviewed. Capillary pressure, relative permeability and hydrodynamic dispersion simulation with the help of network models of pore structure is discussed. Pore structure determination from serial sections is outlined.

Fractal porous media II: Geometry of porous geological structures
Transport in Porous Media, 1987Some geological structures are analysed and found to be fractal. An interesting feature is the very large range of scales involved; the spreading dimension is also measured for some of them. The consequences of these measurements on the analysis of transport processes in porous media are presented - the existence of fractal structures multiplies the ...

Structure-transport relationships in porous media
Magnetic Resonance Imaging, 1996An understanding of adsorption, transport, and reaction processes occurring within porous materials is central to the design and optimisation of chemical processing operations such as gas separations, catalysis, and soil remediation. To address many of the important questions in these areas the process engineer needs to characterise heterogeneities in ...

Hierarchically Structured Porous Materials
2015This chapter presents an overview of the synthesis strategies based on the sol-gel process for the preparation of multimodal porous networks of hierarchically structured functional materials and a brief introduction to their applications as photocatalysts, scaffold templates, and catalyst supports. Until now, many successful examples have been reported
