Abstract Starch-polyacrylic acid-polyvinylsulfonic acid (St-g-PAA-PVSA) graft copoymer was synthesized by gamma radiation as an initiator. The chemical structure, morphology, and thermal stability of the copolymer were investigated using FTIR, SEM, TGA. St-g-PAA-PVSA employed adsorbent for removal Co(II) Eu(III) radionuclides from their aqueous solutions batch adsorption method. Several experim...
ReceiVed January 17, 2008 ReVised Manuscript ReceiVed February 21, 2008 Introduction. In recent years, much attention is paid to the synthesis of copolymers with different compositions and chain architectures, such as linear, grafted, comb-shaped, star-shaped, hyperbranched, and dendrimeric chains with the purpose to establish architecture-property relationships in bulk and in solution. Of thes...
Tailor-made polymers are needed to fully exploit the possibilities of additive manufacturing, constructing complex, and functional devices in areas such as bioelectronics. In this paper, synthesis a conducting biocompatible graft copolymer which can be 3D printed using direct melting extrusion methods is shown. For purpose, copolymers composed by polymer poly(3,4-ethylenedioxythiophene) (PEDOT)...
The interaction between deuterium-labeled Aerosol OT surfactant (AOT-d34) and sterically stabilized poly(methyl methacrylate) (PMMA) latex particles dispersed in nonpolar solvents has been studied using contrast-variation small-angle neutron scattering (CV-SANS). The electrophoretic mobilities (μ) of the latexes have been measured by phase-analysis light scattering, indicating that μ is negativ...
An amphiphilic copolymer, folic acid (FA) modified poly(ethylene glycol)-poly(lactic-co-glycolic acid) (FA-PEG-PLGA) was prepared and explored as a nanometer carrier for the co-delivery of cisplatin (cis-diaminodichloroplatinum, CDDP) and paclitaxel (PTX). CDDP and PTX were encapsulated inside the hydrophobic inner core and chelated to the middle shell, respectively. PEG provided the outer coro...
