**4.10 Dendrimer-reinforced polymeric matrix**

Dendrimer architectures via click chemistry and self-assembly have put forward major reinforced polymeric matrixes. Advanced nanotechnology has discovered new nanoperiodic system through dendrimeric reinforcements in the form of nanodevices, nanomaterials and nanomedicines. This decade has developed many scientific and commercial utilities focusing architecturally on drive characteristics through assorted dendrimeric reinforcements. Dendrimeric reinforcements convey highly defined and well-branched perfect nanostructures obtained through repetitive branched monomer iterative protection and deprotection in contrast to hyperbranch polymeric skeletons. Rationally reconfigured dendrimeric/dendritic polymers are used for drug delivery and catalysis and making light-emitting materials [1, 2]. Today, dendrimer chemistry and catalog of dendrimers offer templates for organic-inorganic hybrid nanomaterials imparting diversified and captivated utility in modern S&T. Hyperbranch polymers are 3D globular low viscous and highly soluble template used in making dendrimer-based organic/inorganic nanohybrids. Organic-inorganic nanohybrids are reconfigured through hyperbranched dendrimeric matrix to get mono-/bimetallic, bimetallic alloys and core/shells. Dendritic hyperbranch polymers and dendrimers with 3D globular arrangement and spherical outline are found to offer high branching density and branching at each repeating unit, which imparts exclusive features like lower viscosity and high solubility/functionality than linear counterparts. Advanced dendritic matrixes blend reconfigured organic/inorganic frameworks via good skeletal processing, thus offering special developed advantageous features like superior elasticity, light-weight, impassive resistance, robust strength, chemical resistance, and thermal stability. Reinforced hyperbranched dendritic matrixes own linear segments of globular end functionality valuable for making many organic-inorganic nanocomposites [2]. Assorted nanohyperbranched composites with unique globular contour with functional end groups are obtained through organic-inorganic dendrimeric templates like polyamidoamine-reinforced nanogold particles, nanocarbon hybrid sols and heterogeneous nanostructures [2]. Intrinsic void-reinforced nanoparticles and metal clusters with enhanced stability are exploited for catalysis, adsorptions and photodetection besides being used in developing antimicrobial sensors/agents [1]. Recent advancement in nanotechnology aids to induce "disordered-to crystalline" features and perform numerous structural reinforcements a way from metal aggregate to nano-crystals in the resultant clusters/matrixes that are especial for electro-catalytic usages [1, 2]. Reinforced carbon black matrix is used for air CO2 absorption/desorption better than Excellion™ ion-exchange membranes.
