Synthesis and characterisation of polyamide dendrimers with systematically varying surface functionality.

Synthesis and Characterization of Polyamide-66/Calcium Carbonate Composites

Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...

Dendrimers: Nanopharmaceuticals for Drug Delivery

Dendrimers are new class of polymeric materials. It is generally described as a macromolecule, which is characterized by its extensively branched 3D structure that provides a high degree of surface functionality and versatility. Dendrimers are highly branched, globular macromolecules with many arms emanating from a central core. The unique properties associated with these dendrimers such as uni...

Synthesis and Characterisation of Silica/Polyamide-Imide Composite Film for Enamel Wire

Polyamide Forward Osmosis Membrane: Synthesis, Characterization and Its Performance for Humic Acid Removal

In this research, modification on the ultrafiltration (UF) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (FO) water treatment. Two monomers, m-Phenylenediamine (MPD) and Trimesoyl chloride (TMC) with different concentrations of MPD (2.0% w/v and 1.0% w/v) were reacted with TMC (0.15% w/v) for interfacial polymerization (...

Dendrimer - a Novel Scaffold for Drug Delivery

A dendrimer described as a macromolecule characterized by its highly branched 3D structure which provides a high degree of surface functionality and versatility. Dendrimers also referred to as the “Polymers of the 21 century.” Dendrimers components, namely (1) an initiator core (2) Interior layers (generations) composed of repeating units, radically attached to the interior core. (3) Exterior (...
