Special Issue Information

Dear Colleagues,

Materials are vulnerable to severe aging, corrosion, cracking, and other deterioration phenomena, resulting in the weakening of mechanical and durability properties. Owing to the special core–shell structure and broad package capability of functional agents, polymeric microcapsules are widely explored and applied for the enhancement of the performance and service lifespan of materials.

 This Special Issue on “Advances in Polymeric Microcapsules for Improving Mechanical and Durability Properties” aims to compile and discuss the latest research on polymeric microcapsule-based materials, with special attention to their improved mechanical and durability properties. Its main scope includes but is not limited to the following topics:

  • Advances in the preparation and characterization of polymeric microcapsules;
  • Optimization of evaluation approaches to polymeric microcapsules;
  • Mechanical properties of microcapsule-incorporated materials;
  • Durability properties of microcapsule-incorporated materials;
  • Enhancement mechanisms of microcapsule-incorporated materials;
  • Applications of microcapsule-incorporated materials.

 It is my pleasure to invite you to submit original research articles or review articles to this Special Issue. Both experimental and theoretical works are also welcome.

A novel polymeric microcapsule was designed and synthesized using perfluoropolyether silane (PFPE-silane) as a superhydrophobic core material and ethyl cellulose (EC) as a shell material. The effects of the stirring rate and the core-to-shell ratio on the synthesized microcapsules were investigated. The physicochemical properties of the polymeric microcapsules were evaluated using scanning electron microscopy, fourier transform infrared spectroscopy, thermogravimetric analysis, laser particle size analysis, and wettability analysis. The results showed that when the stirring rate was 650 rpm and the core-to-shell ratio was 1:1, well-distributed and uniformly dispersed microcapsules could be obtained. The results also indicated that the prepared polymeric microcapsules were spherical particles with micropores on the surface, and they had an average particle size of 165.71 μm. The EC shells could effectively prevent the thermal decomposition of PFPE-silane during cement hydration, and the PFPE-silane also exhibited excellent hydrophobicity. The specially designed structure of this polymeric microcapsule suggests its potential for enhancing the corrosion resistance of reinforced concrete structures. Full article
