A review on new mesostructured composite materials: Part II. Characterization and properties

What is it about?

This overview tries by no means to be complete, containing all existing and important polymer–mesoporous silica nanocomposites that have been published from 2000 to 2017. This review will show characterization, crystallization behavior, materials properties, and rheology of polymer–mesoporous silica hybrid nanocomposites.

Why is it important?

This publication covers the recent developments on the preparation, characterization, and properties of this type of nanocomposite. As can be seen from the examples described, mesoporous silica–polymer nanocomposite presents several advantages: a. These mesostructured forms of silica provide enough intraparticle space for the polymer to impregnate the particles and form a unique composite structure. b. Mesoporous silica are effective reinforcement agents for several engineering polymer systems to improve strength, modulus, and toughness due to the high surface area and favorable interfacial interactions between the polymer and the silica surface. c. The physically confined polymer inside the mesopores shows excellent thermal stability due to the interpenetrating of organic polymer chain within the mesoporous channels. d. OMS provide favorable coefficient of thermal expansion (CTE) properties because the thermal expansion of the confined polymer is perfectly suppressed by the robust silica frameworks. e. The incorporation of the mesoporous silica is a promising approach to reduce the dielectric constant of the polymer due to the incorporation of air voids stored within the mesoporous silica.

Although a significant amount of work has already been done on various aspects of mesoporous silica polymer composite, more research is required in order to understand the exceptional properties observed at the nanoscale and utilize these properties at the macroscale. Recognition of the structure–property relations and proper understanding of the interfaces at the molecular scale will enable the nanoscale design of polymer–mesoporous silica hybrid materials with well-defined architecture that are unprecedented in materials science. Furthermore, polymer–mesoporous silica composite can be produced in large quantities through simple procedures such as mixing, casting, and spin-coating and can be easily scaled up to the large manufacturing processes. Therefore, polymer–mesoporous silica hybrid materials could become unique as bulk-scale mats having commercial applications. With regard to ease of processing, potentially low production costs, low thermal expansion, satisfactory translucencies, improved strength, and tunable properties, we suggest that these materials could become available in medical applications (e.g. orthopedic and dental), sustainable energy applications (e.g. retrofitted concrete slabs), advanced devices (e.g. photoelectronic materials), and fiber/mesoporous silica hybrid polymeric nanocomposites. Finally, we foresee a bright future for mesoporous silica–composite material both as bulk commodities and in fine nanotechnological ventures. The number of listed materials is by no means complete, nerveless, we hope to increase the interest and promote some discussion on this very important field which will attain further consideration in the future.
