Porous polymeric materials, such as textile fabrics, are elastic and widely used in our daily life for garment and household products. The mechanical and dynamic heat transfer properties of porous polymeric materials, which describe the sensations during the contact process between porous polymeric materials and parts of the human body, such as the hand, primarily influence comfort sensations a...

Condensation of 2,5-diethoxyterephthalohydrazide with 1,3,5-triformylbenzene or 1,3,5-tris(4-formylphenyl)benzene yields two new covalent organic frameworks, COF-42 and COF-43, in which the organic building units are linked through hydrazone bonds to form extended two-dimensional porous frameworks. Both materials are highly crystalline, display excellent chemical and thermal stability, and are ...

Zeolites are crystalline microporous materials with well-defined and uniform pore structure that find extensive industrial uses as adsorbents, catalysts and ion exchangers [1-2]. Zeolite films supported on different materials have been successfully prepared and have potential applications as highly selective membrane separators, membrane reactors, chemical sensor and microdevices [3-10]. Most o...

Bombyx mori silk fibroin (SF) is one of the most important fibers among biomedical porous materials due to its superior machinability, and biocompatibility. It is also chosen for its biodegradability and bioresorbability. It is a protein-based fiber. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing and biocompatibility of SF ...

Porous carbon materials with high specific surface areas and superhydrophobicity have attracted much research interest due to their potential application in the areas of water filtration, water/oil separation, and oil-spill cleanup. Most reported superhydrophobic porous carbon materials are fabricated by complex processes involving the use of catalysts and high temperatures but with low through...

Porous carbon materials have numerous applications due to their thermal and chemical stability, high surface area and low densities. However, conventional preparing porous carbon through zeolite or silica templates casting has been criticized by the costly and/or toxic procedure. Creating three-dimensional (3D) carbon products is another challenge. Here, we report a facile way to prepare porous...

Hierarchically porous materials displaying multimodal pore sizes are desirable for their improved flow performance coupled with high surface areas. In the last five years, a tremendous amount of research has focused upon the synthesis and applications of hierarchically porous materials. This review aims to open up a new avenue of research in this exciting field. At first, recent progress in the...

We report on the preparation of hybrid, organic-inorganic porous materials derived from polyhedral oligomeric vinylsilsesquioxanes (vinylPOSS) via a single-step molding process. The monolithic, large surface area materials are studied with a particular focus on morphology and porous properties. Radical vinyl polymerization of the nanometer-sized POSS building blocks is therefore utilized via a ...

We investigate the gas flow behavior of unidirectional porous ceramics processed by ice-templating. The pore volume ranged between 54% and 72% and pore size between 2.9 [Formula: see text]m and 19.1 [Formula: see text]m. The maximum permeability ([Formula: see text] [Formula: see text] m[Formula: see text]) was measured in samples with the highest total pore volume (72%) and pore size (19.1 [Fo...

Balloting on a new test method for use in the ranking of porous packaging materials used in sterile packaging applications by their ability to provide bacterial holdout was completed in July 2007 by ASTM International Committee F02 Flexible Barrier Packaging. As a result of this balloting, there is a new test method available for evaluating the barrier capabilities of porous materials intended ...
