Abstract
The emerging areas of polymer nanocomposites, as some are already in use in industrial applications and daily commodities, have the potential of offering new technologies with all manner of prominent capabilities. The incorporation of nanomaterials into polymeric matrix provides significant improvements, such as higher mechanical, thermal or electrical properties. In these materials, interface/interphase of components play a crucial role bringing additional features on the resulting nanocomposites. Among the various preparation strategies of such materials, an appealing strategy relies on the use of click chemistry concept as a multi-purpose toolbox for both fabrication and modulation of the material characteristics. This review aims to deliver new insights to the researchers of the field by noticing effective click chemistry-based methodologies on the preparation of polymer nanocomposites and their key applications such as optic, biomedical, coatings and sensor.
Highlights
Dispersing nano-sized reinforcing agents in the polymeric matrix yields polymer nanocomposites, and such materials exhibit superior physical, mechanical and thermal properties compared to their parent components
A novel strategy was employed as chemically stitched graphene oxide (GO) sheets were fabricated by covalent click coupling of bare azide and alkyne functional GOs
In a subsequent initiator was attached onto the nanoparticle surface, SI-atomnanocomposite transfer radicalformation polymerization (ATRP) was conducted by using butyl study of the same group, the role of polymer matrix in self-healing abilities of silica NPs methacrylate along with maleimide- or furan-functionalized methacrylate monomers
Summary
Dispersing nano-sized reinforcing agents in the polymeric matrix yields polymer nanocomposites, and such materials exhibit superior physical, mechanical and thermal properties compared to their parent components. Despite the fact that polymer nanocomposites exhibit great promise for development of potentially useful materials, the fabrication and processing of these materials is usually not straightforward Important parameters, such as careful selection of polymer matrix, choosing appropriate nanofiller by considering entire nanocomposite system, the interactions between the components and their morphology as well as interfacial characteristics must be undertaken to achieve desirable end-goals of materials. The interfacing between the polymer matrix and the nanofiller and the interaction of individual components with themselves often necessitate careful analysis of the system and may require organic treatment and chemical modification of components and post-fabrication modification to impart desired properties [5] In this sense, recently developed click chemistry reactions always have great relevance to enhance the properties of polymer nanocomposites.
