Prevascularization of porous biodegradable polymers
Biotechnology and Bioengineering, 1993AbstractHighly porous biocompatible and biodegradable polymers in the form of cylindrical disks of 13.5 mm diameter were implanted in the mesentery of male syngeneic Fischer rats for a period of 35 days to study the dynamics of tissue ingrowth and the extent of tissue vascularity, and to explore their potential use as substrates for cell ...

Swelling of polymers in porous media
The Journal of Chemical Physics, 2009The swelling of polymers in random matrices is studied using computer simulations and percolation theory. The model system consists of freely jointed hard sphere chains in a matrix of hard spheres fixed in space. The average size of the polymer is a nonmonotonic function of the matrix volume fraction, ϕm. For low values of ϕm the polymer size decreases

Porous Polymers for Biological Fixation
Clinical Orthopaedics and Related Research, 1988Porous polymers are recommended as coatings for femoral stems on the basis of their low modulus, which allows uniform distribution of stress to surrounding bone and the fabrication of more flexible stems by reducing the metallic cross section. Application of the porous polymer coating to the metallic substrate reduces metal ion release; the polymer ...

Abstract Porous polymers offer considerable scope and opportunities for energy and environmental applications, attributable to their unique pore environments together with structural and chemical diversities. However, the application coverage is restricted by the lack of solution-processability of most porous polymers.

Porous Polymers by Emulsion Templating
Macromolecular Symposia, 2005AbstractHighly porous and permeable polymers are produced by polymerisation of the continuous phase of high internal phase emulsions (HIPEs). The morphology and properties of the resulting PolyHIPE materials can be varied, allowing the materials to be optimised for a variety of applications.

This study was designed to answer the question whether the chromatographic performance of porous polymers — serving here as a model system for pressure-sensitive separation media of relatively large mass transfer resistance — could be improved (a) by imposing on them a chromatographically favorable, extrinsic macrostructure and (b) by protecting that ...

Features of extrusion for mixtures of polyvinyl chloride and a pore-forming agent with the aim of preparing very porous materials are studied. It is shown that extrusion rate depends on the particle size of the pore-forming agent with the same volume content.
