Natural dye modification of polyethylene oxide: optical characterization and dielectric enhancement

open access: yesJournal of Materials Science: Materials in Engineering
This study explores the optical properties of polyethylene oxide (PEO) modified with natural dye extracted from hollyhock (HH) flowers. This study is a green chemistry approach to reduce the optical band gap of PEO polymer.

PEO-PPO-PEO triblock copolymers and their biomedical applications

open access: yes, 2006
Thermoreversible polymeric systems represent an interesting class of materials that can be tailored for a wide range of application. PEO-PPO-PEO copolymer systems show thermoreversible gelation around body temperature and therefore are of particular ...

PEO and PEO-heparin modified surfaces for blood contacting applications

open access: yes, 2001
The synthesis and characterization of various thiolated polyethylene oxide (PEO) polymers constitute a significant part of the work, from linear PEOs with different molecular weights, and different end groups, to star-type, multiarmed PEOs, to linear ...
