Special Issue Information

Dear Colleagues,

Polymer-inorganic hybrid materials include a broad variety of systems. For instance, a polymer can act as a matrix for dispersed inorganic nanoparticles thus constituting what is known by the name of nanocomposites. A special case of nanocomposites comprises inorganic particles which are linked by covalent bonds with the polymer matrix. Also, materials with a tightly bound interconnected network of inorganic and organic species have been prepared. Besides other preparation methods, processes based on in situ particle synthesis including sol-gel processes have frequently been applied. Such methods can prevent agglomeration of inorganic species in the final products, which is often a problem when preformed nanoparticles and polymers are mixed, unless the particles are modified with an organic surface layer. Importantly, polymer-inorganic hybrids can exhibit materials properties which are more pronounced or even differ from those of comparable polymer composites with larger inorganic particles, such as optical properties (e.g., transparency and color, including dichroism), magnetic properties (superparamagnetism), mechanical properties, chemical properties (catalytic or sensory activity), and gas barrier properties. Thus, polymer-inorganic hybrid materials are considered to find application in various areas, for example in optics, catalysis, sensor technology, electronics, magnetism, mechanics, and food and beverage packaging.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed Open Access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs).

Abstract
In this study, we prepared a mesoporous carbon with hexagonally packed mesopores through evaporation-induced self-assembly (EISA)—with the diblock copolymer poly(ethylene oxide-b-ε-caprolactone) (PEO-b-PCL) as the template (EO114CL84), phenolic resin as the carbon precursor, hexamethylenetetramine (HMTA) as

In this study, we prepared a mesoporous carbon with hexagonally packed mesopores through evaporation-induced self-assembly (EISA)—with the diblock copolymer poly(ethylene oxide-b-ε-caprolactone) (PEO-b-PCL) as the template (EO114CL84), phenolic resin as the carbon precursor, hexamethylenetetramine (HMTA) as the curing agent, and star octakis-PEO-functionalized polyhedral oligomeric silsesquioxane (PEO–POSS) as the structure modifier—and subsequent carbonization. We then took the cylindrical mesoporous carbon as a loading matrix, with AgNO3 and Pd(NO3)2 as metal precursors, to fabricate Ag nanowire/mesoporous carbon and Pd nanoparticle/mesoporous carbon nanocomposites, respectively, through an incipient wetness impregnation method and subsequent reduction under H2. We used transmission electron microscopy, electron diffraction, small-angle X-ray scattering, N2 isotherm sorption experiment, Raman spectroscopy, and power X-ray diffraction to investigate the textural properties of these nanometal/carbon nanocomposites. Most notably, the Raman spectra of the cylindrical mesoporous carbon, Ag/mesoporous carbon, and Pd/mesoporous carbon revealed interesting phenomena in terms of the ratios of the intensities of the D and G bands (ID/IG), the absolute scattering intensities, and the positions of the D bands.
