Master's Theses and Doctoral Dissertations
Amphiphilic diblock copolymers are composed of hydrophilic and hydrophobic regions. When they are exposed to water, the hydrophobic blocks aggregate to form a hydrophobic core surrounded by hydrophilic regions outside to give a core-shell micelle. These micelles have many potential applications, such as a drug delivery system, surfactants, or nanoreactor. Many studies have been done to optimize the performance of these copolymers. In this thesis work, nine dual temperature- and pH-responsive poly(acrylic acid-block-N-isopropylacrylamide) (PAA-b-PNIPAM) diblock copolymers with different relative chain lengths of the hydrophobic and hydrophilic blocks were synthesized by reversible addition fragmentation chain transfer polymerization. The preliminary results showed …
