Special Issue Information

Dear Colleagues,

A semiconductive pure silicon is used as a basic electronic material for production of computer chips and other electronic devices.

Many functional silanes of different chemical structures containing reactive groups, mostly bound to silicon atom, but also quite often attached to carbon atom are applied for modification of surface properties of different polymeric and inorganic materials, e.g., fillers.

Silicones (polysiloxanes), containing silicon and oxygen atoms in their main chains and organic substituents bound to silicon, are a large and most important group of various inorganic-organic (hybrid) compounds and materials. Mainly poly(dimethylsiloxanes) (PDMS) are used. Silicones are applied as oils, rubbers, and resins (W. Noll, 1968; M.A. Brook, 2000). They have many unusual features - they exhibit excellent chemical, physical, and electrical properties. Even an addition of  a very small amount of silicones causes a crucial improvement of properties of modified materials. Silicones increase hydrophobicity and improve water resistance and thermal stability of many materials.

Other organosilicon polymers, and especially, polysilanes, polycarbosilanes, and polysilazanes, are raw materials for fabrication of polymer-derived high-tech ceramic materials. Silicon-based polymers and polymeric materials as well as reactive silane coupling agents are used in many fields – from industry, through everyday life commodity goods and cosmetics, to medicine. Their universal properties decide that they are very useful and attractive materials and components in a very wide range of products.

A continuously growing interest in applications of reactive silanes, all kinds of silicones, chemically modified nanosilica, different composites, silicon photovoltaic cells, and silicon nanowires has been still observed in many different fields of science, the chemical technology, and especially in materials science. Original contributions and reviews are welcome.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short 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 thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly 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 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The article describes new silicone self-adhesive adhesives modified with the addition of talc. The obtained self-adhesive materials were characterized to determine their adhesive properties (adhesion, cohesion, and adhesion) and functional properties (pot life of the composition, shrinkage, and thermal properties of adhesives). Novel materials exhibited high thermal resistance above 225 °C while maintaining or slightly reducing other values (adhesion, cohesion, shrinkage, and tack). Selected composition: T 0.1 was used to prepare self-adhesives in industrial-scale production. Moreover, conducted test results revealed that the addition of talc delayed the thermal decomposition of the adhesive and provided reduced intensity of smoke emissions during combustion as well as the flammability of the adhesive layer.
