Abstract
This work describes the TEM morphology analysis of amphiphilic alternating copolymers of maleic anhydride MA with different αolefins 1hexene 1octene 1dodecene synthesized by radicalinitiated intercalative copolymerization of preintercalated MA···organoclay complexes in the presence of two types of organoclay such as reactive octadecyl aminemontmorillonite ODAMMT and nonreactive dimethyldidodecyl ammoniumMMT DMDAMMT TEM analyses of all the nanocomposites indicate the formation of symmetric or nonsymmetric coreshell morphologies Energy dispersive Xray spectroscopy analyses were used to study the occurrence of the element in the polyMAaltαolefin/organomontmorillonite nanocomposites A role of surfactant in these nanosystems insists on alternating copolymer segments with given hydrophobic/hydrophilic balance and surface organomodifiers of MMT clays Highly organized selfassembly with symmetric coreshell morphology were formed in nanosystems prepared in the presence of DMDAMMT clay as compared with ODAMMT claycontaining nanosystems The relatively long branched olefin fragments significantly improve image parameters of coreshell morphology where some of the core structures contain accumulated and finely dispersed silicate particles at nano level around 2–25 nm This observed phenomenon has brought a new approach for future utilization of these nanosystems in controlled drug delivery and anticancer applications with essentially prolonged activity
