Special Issue Information

Dear Colleagues,

Porous polymer materials play a significant role in industry and our daily lives. The properties of porous polymer materials (especially mechanical ones) have been continuously improved in different ways. One of the methods to improve the mechanical and physical properties of polymers is their combination with different micro- and nanoscale materials. Customization of the initial porous polymer matrix with various materials helps to not only improve some of the already known and outstanding properties of the given polymer, but it also adds new ones (e.g., combination polyurethane foams with different nanofillers, such as carbon nanotubes or aluminosilicates, can give flame-retardant properties to polymer foams). Evidently, structural investigation of polymer composites is of great importance since the filler’s size, texture, charge, as well as its distribution in the polymer matrix can change the polymerization process and polymer microstructure, and hence, dramatically influence the properties of the composite material.

This Special Issue aims to provide a forum for the discussion of recent advances in the investigation of the structure of porous polymer composites and structure–properties correlations. Authors are encouraged to submit contributions on synthetic polymer and biopolymer composites, as well as natural or mineral micro- and/or nanofillers. The scope of this Special Issue ranges from basic research on composites’ structures to comprehensive research on structure–properties correlations. This issue also includes studies on the life cycle assessment or environmental impact of polymer composites, as well as possible uses of these materials.

A new para-aramid aerogel based on a polymer made by the reaction of terephthaloyl dichloride with 2-(4-aminophenyl)-1H-benzimidazol-5-amine (PABI) is introduced. The aerogel readily bound Pd (+2) ions and was used as a hydrogenation catalyst in some industrially actual reactions. The new material, which did not contain p-phenylenediamine moieties, was prepared in two form factors: bulk samples and spherical pellets of 700–900 μm in diameter. Aerogels were synthesized from 1% or 5% solutions of PABI in N,N-dimethylacetamide via gelation with acetone or isopropanol and had a density of 0.057 or 0.375 g/cm3 depending on the concentration of the starting PABI solution. The specific surface area of the obtained samples was 470 or 320 m2/g. Spherical pellets containing Pd were prepared from a solution of PdCl2 in PABI and were used as heterogeneous catalysts for the gas-phase hydrogenation of unsaturated organic compounds presenting the main types of industrially important substrates: olefins, acetylenes, aromatics, carbonyls, and nitriles. Catalytic hydrogenation of gaseous hexene-1, hexyne-3, cyclohexene, and acrylonitrile C=C bond proceeded with a 99% conversion at ambient pressure, but the catalyst failed to reduce acetone at 150 °C and benzene and ethyl acetate even at 200 °C. The only product of acrylonitrile hydrogenation was propionitrile. The prepared catalysts showed high selectivity, which is important for the chemistry of complex organic compounds. Full article

First introduced in 1954, polyurethane foams rapidly became popular because of light weight, high chemical stability, and outstanding sound and thermal insulation properties. Currently, polyurethane foam is widely applied in industrial and household products. Despite tremendous progress in the development of various formulations of versatile foams, their use is hindered due to high flammability. Fire retardant additives can be introduced into polyurethane foams to enhance their fireproof properties. Nanoscale materials employed as fire-retardant components of polyurethane foams have the potential to overcome this problem. Here, we review the recent (last 5 years) progress that has been made in polyurethane foam modification using nanomaterials to enhance its flame retardance. Different groups of nanomaterials and approaches for incorporating them into foam structures are covered. Special attention is given to the synergetic effects of nanomaterials with other flame-retardant additives. Full article
