With growing demand for medical information and health applications in pregnancy, the potential of electronic (eHealth) mobile (mHealth) solutions clinical care is increasingly unfolding. However, we still do not know how pregnant women engage with apps, such apps impact routine care, whether benefit expectations are met. Whereas recent research has raised subject user distribution analyzed content pregnancy applications, there a significant knowledge gap regarding what like dislike about...
For biomedical applications, superparamagnetic nanoparticles (MNPs) have to be coated with a stealth layer that provides colloidal stability in biological media, long enough persistence and circulation times for reaching the expected medical aims, anchor sites further attachment of bioactive agents. One such molecules designed synthesized by us, poly(polyethylene glycol methacrylate-co-acrylic acid) referred as P(PEGMA-AA), was demonstrated make MNPs reasonably resistant cell...
The precise molecular engineering of amphiphilic diblock copolymers as thermoresponsive polymer ionic liquids (PILs) couples polyisobutylene (PIB) and poly(2-ethyl-2-oxazoline) (PEtOx) blocks via an imidazolium cation. It enables thermal switching micellar self-assembly yields nanostructured hydrogels. Just one liquid (IL)-type cation is readily incorporated into the backbone PIB–IL–PEtOx block by terminating cationic 2-ethyl-2-oxazoline (EtOx) ring-opening polymerization alkylation...
Polyelectrolyte hydrogels have the advantage of a high swelling ratio and to respond changes in pH ionic strength which gives them useful characteristics for biomedical applications. To investigate possibility synthesize from vinylphosphonic acid (VPA), first free radical copolymerization VPA methyl acrylate (MA) was investigated at temperatures between 60 80 °C. Second with ethylene glycol diacrylate (EGDA) °C studied obtain hydrogel. These copolymerizations were successful. For...
Systematic investigations are carried out on the synthesis of a series new, unique ABA‐type triblock copolymers consisting hydrophobic and chemically inert polyisobutylene (PIB) inner hydrophilic comb‐shaped poly(poly(ethylene glycol) methacrylate) (PPEGMA) polymacromonomer as an outer block. Telechelic PIB macroinitiators with narrow molecular weight distributions (MWD) synthesized by quasiliving carbocationic polymerization isobutylene bifunctional initiator followed quantitative chain end...
AbstractNovel, unique amphiphilic pentablock terpolymers consisting of the highly hydrophobic polyisobutylene (PIB) mid-segment attached to hydrophilic combshaped poly(poly(ethylene glycol) methacrylate) (PPEGMA) polymacromonomer chains, which are coupled poly(methyl (PMMA) outer segments were synthesized by combination quasiliving carbocationic polymerization and atom transfer radical (ATRP). First, a bifunctional PIB macroinitiator was prepared subsequent quantitative chain end...
Novel poly(dithiophosphate)s (PDTPs) were successfully synthesized under mild conditions without any additive in the presence of THF or toluene diluents at 60 °C by a direct, catalyst-free reaction between abundant phosphorus pentasulfide (P4S10) and glycols such as ethylene glycol (EG), 1,6-hexanediol (HD) poly(ethylene glycol) (PEG). GPC, FTIR, 1H 31P NMR analyses proved formation macromolecules with dithiophosphate coupling groups having P=S P-SH pendant functionalities. Surprisingly,...
Upper critical solution temperature (UCST)‐type thermoresponsive behavior of poly(ethylene glycol)–poly(acrylic acid) (PEG–PAA) and poly(poly(ethylene glycol) methacrylate)–poly(acrylic (PPEGMA–PAA) interpolymer complexes has been observed in isopropanol. For these investigations, PPEGMA PAA with various average molecular weights have synthesized by atom transfer radical polymerization. It found that both the PEG lower cloud point temperatures ( T cp ) than its mixed polymer solutions PAA,...
Polymers based on renewable monomers are projected to have a significant role in the sustainable economy, even near future. Undoubtedly, cationically polymerizable β-pinene, available considerable quantities, is one of most promising bio-based for such purposes. In course our systematic investigations related catalytic activity TiCl4 cationic polymerization this natural olefin, it was found that 2-chloro-2,4,4-trimethylpentane (TMPCl)/TiCl4/N,N,N',N'-tetramethylethylenediamine (TMEDA)...
The lithium-sulfur batteries (LISB) possess issues, such as insulating nature of sulfur, polysulfide shuttle, volume expansion and self-discharge, which impede its widespread commercialization. To address the carbon-based materials were utilised. However, increasing amount carbon content in cathode matrix reduces specific capacity gravimetric energy density. above-mentioned we believe that these can be overcome by developing or utilising sulfur confining materials, favourably macromolecules,...
Endfunctional polymers possess significant industrial and scientific importance. Sulfonyl endgroups, such as tosyl nosyl endfunctionalities, due their ease of substitution are highly desired for a variety polymer structures. The sulfonylation hydroxyl-terminated polyisobutylene (PIB-OH), chemically thermally stable, biocompatible, fully saturated polymer, with chloride (TsCl) (NsCl) is presented in this study.
