Thermosensitive star-shaped eight-arm poly-2-alkyl-2-oxazolines (M = 21,000 g mol−1) was synthesized. The arms were gradient copolymers of 2-ethyl-2-oxazoline (EtOx) and 2-isopropyl-2-oxazoline (iPrOx). The more hydrophilic EtOx units prevailed near the calix[8]arene core. For comparison, model linear gradient copolymer (M = 3800 g mol−1) was inves...

The significant developments in the field of polymer have advanced the synthesis of polymer-based materials and have expanded their use in a wide variety of applications. Today, polymers can be designed to change their properties in response to a single stimulus or multiple stimuli. Such types of polymers are called stimuli-sensitive or stimuli-res...

In this study synthesis of a drug delivery system (DDS) is described which has several merits over its counterparts. In order to synthesize this nano-carrier, graphene oxide nano-sheets are used to accommodate MCM-41 nanoparticles. Furthermore Fe3O4 nanoparticles are introduced to this nano-material to produce a traceable nanoparticle. Since cancer...

The field of thermo- and pH-sensitive copolymers, with applications in controlled drug delivery, is enriched with the copolymer based on N-vinylcaprolactam and maleic acid (VCL–MAc) that is synthesized and characterized in this paper. Cloud point measurements and dynamic light scattering are used to characterize the phase transition of VCL–MAc copo...

CaCO3/aliphatic poly(urethane-amine) (PUA)/sodium polystyrene sulfonate (PSS) hybrid composites with dual-responsive controlled drug delivery property had been prepared via electrostatic interaction. Aliphatic PUA and PSS were employed as smart polyelectrolytes. PSS was also served as crystal growth additive to control the morphology of CaCO3 micro...

Nanocomposite hydrogels of poly(2-acrylamido-2-methyl-1-propanesulfonic acid) containing graphene were prepared by radical polymerization. Their swelling properties in response to ionic strength and electrical stimuli were assessed. Graphene was obtained through an easy and convenient method lately developed by our research group, which consists in...

Novel of temperature and pH sensitive hydrogels composed of polyampholyte (casein) and poly(N-isopropylacrylamide) were successfully synthesized via free radical polymerization. The swelling behavior of the obtained hydrogel was investigated and it was found that the synthesized hydrogel has a sensitivity to temperature, pH, and the crosslinker con...

This manuscript describes the formation of spherical nanostructures on surfaces by interfacial migration of amphiphilic block copolymer micelles. The micelles are formed by macrophase separation of a polymer blend composed of polystyrene-b-poly(acrylic acid) (PS-b-PAA) block copolymers and a high molecular weight polystyrene matrix. The micelles fo...
