A side-on liquid crystalline monomer, 2,5-bis[(4-hexyloxyphenyl)oxycarbonyl]styrene) (HPCS), was successfully polymerized via atom transfer radical polymerization (ATRP). The polymerization was catalyzed by CuBr/PMDETA in chlorobenzene at 90°C with (1-bromoethyl)benzene as the initiator. The polymers have narrow MWD. It is the second example of mesogen-jacketed liquid crystalline polymer (MJLCP...

Abstract Traditional mechanochemically controlled reversible‐deactivation radical polymerization (RDRP) utilizes ultrasound or ball milling to regenerate activators, which induce side reactions because of the high‐energy and high‐frequency stimuli. Here, we propose a facile approach for tribochemically atom transfer (tribo‐ATRP) that relies on contact‐electro‐catalysis (CEC) between titanium ox...

A promising strategy for the controlled synthesis of inorganic/polymeric nanocomposites may be sustained by fabricating cross-linked PbS nanoparticles/polymer composite thin films through combining surface-initiated atom transfer radical polymerization (ATRP) and gas/solid reaction. The introduction of Pb ions through the extension of surface-initiated ATRP to the monomers containing metal ions...

This study reported the application of an interactive Open Education Resource, namely, open virtual experiment simulator education tool (OVESET), in teaching kinetics atom transfer radical polymerization (ATRP) a polymer science classroom. The OVESET ATRP kinetic aims at improving students’ inductive reasoning skills. Students were encouraged to perform experiments systematically examine influe...

Desorption of thiol-based self-assembled monolayers on gold surfaces makes surface-initiated atom transfer radical polymerization (SI-ATRP) challenging and results in reduced density “grafted from” polymer fi lm. In this work, in situ attenuated total refl ectance-Fourier transform infrared (ATR-FTIR) spectroscopy shows that copper-based catalysts typically used in SI-ATRP cause substantial des...

Abstract Atom-transfer radical polymerization (ATRP) is a well-known technique for controlled polymer synthesis. However, the ATRP usually employed toxic heavy metal ionas as catalyst and was susceptible to molecular oxygen, which made it should be conducted under strictly anoxic condition. Conducting ambient biocompatible conditions major challenge. In this study, cytochrome C explored an effi...

Herein we present a simple batch method to control polymer dispersity using mixture of two ATRP initiators with different reactivities.

Surface initiated atom transfer radical polymerization (SI-ATRP) is one of the most versatile technique to modify the surface properties of material. Recent developed metal free SIATRP makes such technique more widely applicable. Herein photo-induced metal-free SI-ATRP of methacrylates, such as methyl methacrylate, N-isopropanyl acrylamide, and N,Ndimethylaminoethyl methacrylate, on the surface...

To enhance the cytocompatibility of polycaprolactone (PCL), cell-adhesive gelatin is covalently immobilized onto the PCL film surface via two surface-modified approaches: a conventional chemical immobilization process and a surface-initiated atom transfer radical polymerization (ATRP) process. Kinetics studies reveal that the polymer chain growth from the PCL film using the ATRP process is form...

Cationic polymers with various structures have been widely investigated in the areas of medical diagnostics and molecular biology because of their unique binding properties and capability to interact with biological molecules in complex biological environments. In this work, we report the grafting of a linear cationic polymer from an atom transfer radical polymerization (ATRP) initiator bound t...
