Swelling Deswelling Behavior of PS‐PNIPAAM Copolymer Particles and PNIPAAM Brushes Grafted from Polystyrene Particles & Monoliths

open access: yesMacromolecular Materials and Engineering, 2008
AbstractTwo sets of emulsion particles have been synthesized. In the first set, surfactant free emulsion was used to directly synthesize PS‐PNIPAAM copolymer particles. In the second set, polystyrene particles with an ATRP initiator shell were first synthesized and subsequently grafted with PNIPAAM brushes.

Characterization of PNIPAAm photografted on PET and PS surfaces

Applied Surface Science, 2005
Abstract Aqueous solution of poly(N-isopropylacrylamide), or PNIPAAm, possess lower critical solution temperature (LCST) around 32–33 °C. Below this temperature the PNIPAAm is hydrophilic and above presents hydrophobic characteristics. In this work, virgin or oxidized films of PET and PS were submitted to surface modification by grafting of PNIPAAm ...

Biocompatibility of thermo‐responsive PNIPAAm‐PLLA‐PNIPAAm triblock copolymer as potential drug carrier

Polymers for Advanced Technologies, 2015
This work aims to evaluate the cytocompatibility and hemocompatibility of thermo‐responsive polymers as potential drug carrier. Thermo‐responsive poly(N‐isopropyl acrylamide) (PNIPAAm) and poly(N‐isopropyl acrylamide)‐poly(l‐lactide)‐poly(N‐isopropyl acrylamide) (PNIPAAm‐PLLA‐PNIPAAm) triblock copolymer were synthesized by atom transfer radical ...
