Special Issue Information

Dear Colleagues,

Composite materials can be defined as a matter made of two or more materials possessing different chemical or physical properties, where after merging, the resulting product shows disparate, often superior, characteristics. For the case of the nanocomposite, the constituent materials should have distinctive phases, and the dimension of at least one of them should be less than 100 nanometers. Sometimes, the structure of a nanocomposite has nano-scale repeat distances between the different phases that make up the material. One of the examples of nanocomposites can be host–guest systems. Here, silica seems to be an ideal matrix. Such silica-based nanocomposites are widely used in electronics, energy storage, sensing, catalysis, or even in antimicrobial systems. Their synthesis has become an important research field in recent years.

This Special Issue is devoted to silica-based nanocomposites. Its aim is to publish several high-quality original research articles along with reviews presenting advances in the preparation, characterization, and application of such materials, as well as the relevant prospects, opportunities, and challenges connected with such systems.

Potential topics include but are not limited to:

  • Synthesis of silica-based nanocomposite materials;
  • Functional silica-based materials;
  • Ordered porous functional thin films;
  • Methods of thin films functionalization;
  • Multifunctional and intelligent materials based on silica matrices;
  • Characterization methods of silica-based nanocomposites;
  • Porous silica-based nanocomposites;
  • Application of silica-based nanocomposites.

Functionalization of the NiTi Shape Memory Alloy Surface by HAp/SiO2/Ag Hybrid Coatings Formed on SiO2-TiO2 Glass Interlayer
Materials 2020, 13(7), 1648; https://doi.org/10.3390/ma13071648 - 02 Apr 2020

The surface modification of NiTi shape memory alloys is a method for increasing their multi-functionalities. In our solution, hydroxyapatite powder was mixed with a chemically synthesized silicon dioxide/silver (nSiO2/Ag) nanocomposite in a different weight ratio between components (1:1, 5:1, and 10:1) and then electrophoretically deposited on the surface of the NiTi alloy, under various time and voltage conditions. Subsequently, uniform layers were subjected to heat treatment at 700 °C for 2 h in an argon atmosphere to improve the strength of their adhesion to the NiTi substrate. A change in linear dimensions of the co-deposited materials during the sintering process was also analyzed. After the heat treatment, XRD, Raman, and Scanning Electron Microscopy (SEM) + Energy Dispersive Spectrometer (EDS) studies revealed the formation of completely new composite coatings, which consisted of rutile and TiO2-SiO2 glass with silver oxide and HAp particles that were embedded into such coatings. It was found that spalling characterized the 1:1 ratio coating, while the others were crack-free, well-adhered, and capable of deformation to 3.5%. Coatings with a higher concentration of nanocomposite were rougher. Electrochemical impedance spectroscopy (EIS) tests in Ringer’s solution revealed the capacitive behavior of the material with high corrosion resistance. The kinetics and susceptibility to pitting corrosion was the highest for the NiTi electrode that was coated with a 5:1 ratio HAp/nSiO2/Ag hybrid coating. Full article
