The internal structure of PMETAC brush/gold nanoparticle
The particle number density as well as the particle distribution depend strongly on the pH value of the incubation medium: a rather non-homogeneous assembly (2D assembly) is found when the PMETAC brush is incubated in AuNP suspension at pH 4, while a …

Conformational Dynamics and Responsiveness of Weak …
PDMAEMA and PMETAC have been selected as canonical models for weak and strong polyelectrolytes whose complex conformational behavior is particularly challenging for the development and validation of atomistic models. The GROMOS-derived atomic parameters reproduce the experimental swelling coefficients obtained from ellipsometry measurements for ...

Interactions between Polyelectrolyte Brushes and
We have investigated the interactions between the positively charged poly[2-(methacryloyloxy)ethyltrimethylammonium chloride] (PMETAC) brushes and the Hofmeister anions and the interactions between the negatively charged poly(3-sulfopropyl methacrylate potassium) (PSPMA) brushes and the Hofmeister cations using a combination of quartz crystal microbalance with …

Synthesis of polyampholytic diblock copolymers via RAFT
A PMETAC 60 precursor was prepared at 30% w/w solids via RAFT aqueous solution polymerization of METAC at 44 °C using a CECPA RAFT agent and VA-044 initiator at pH 6, see Scheme 1.In this case, the solution pH had little effect on the polymerization, since the METAC monomer possesses no basic character – it retains its permanent cationic charge regardless of the solution pH.

Continuously Variable Regulation of the Speed of Bubble
Dec 17, 2018 · A micromotor with a gearbox: The continuously variable speed regulation of micromotors has been achieved by grafting salt-responsive poly[2-(methacryloyloxy)ethyltrimethylammonium chloride] (PMETAC) brushes onto bubble-propelled Janus microcapsule motors.Adjustment of the wetting properties of PMETAC brushes by counterion exchange modulates the speed in an accurate and …

Nov 24, 2021 · The samples with PAA and PMETAC degraded more, and in the end, they lost more of their mass . At 800 °C, the GCe lost 22.6%, the GCePN lost 24.6%, the GCePM lost 33.7% and the GCePA lost the most of its mass (45.1%). Small mass losses could be seen at around 100 °C, which were attributed to the water absorbed in the monolithic mass.
