In the present study, a high performance, tough, antimicrobial, hyperbranched epoxy nanocomposite is fabricated by the incorporation of neem oil-immobilized organo-modified montmorillonite nanoclay. The immobilization of neem oil with organo-modified montmorillonite nanoclay is performed by the combined effect of mechanical and ultrasonic forces under ambient conditions. This immobilization is confirmed by FTIR and XRD studies. FTIR, XRD, SEM and TEM analyses also confirm the formation of the exfoliated nanocomposite. The dose-dependent enhancements of tensile strength (50%), elongation at break (3-fold), toughness (5.5-fold) and thermal stability (20 1C) of the pristine epoxy thermoset are observed for the nanocomposite. Antimicrobial studies are performed by growth curve and zone-ofinhibition analyses against different bacteria and a fungus at different doses of neem oil-immobilized organo-modified montmorillonite nanoclay. The nanocomposite with 50 wt% neem oil-immobilized organo...

Dendritic polymers (dendrimers and hyperbranched polymers) are becoming increasingly popular due to their vast range of uses. Due to their distinctive and novel qualities, they have demonstrated a strong interest. Since its discovery, dendritic polymers have become a potential material for many research applications, ranging from biomedical and tissue engineering to catalytic and energy applications. Since then, dendritic polymers’ unique features have become a promising platform for a variety of uses. Dendritic polymers have made great progress in overcoming basic and technological problems related to their biomedical and energy applications. This review summarizes the strategies of synthesizing dendrimers and hyperbranched polymers. Further, the review highlights the applications of dendrimers and hyperbranched polymers in many study fields such as drug delivery, gene delivery, tissue engineering, catalysis, and energy storage. This review concludes with future avenues to be explored for the applications of dendritic polymers.
