Synthesis and dissipative particle dynamics simulation of cross-linkable fluorinated diblock copolymers: self-assembly aggregation behavior in different solvents

Abstract

Developing microstructures, such as low molecular aggregates, spherical micelles and multi-compartment micelles, is an expanding area of research in Materials Science. By applying an atom transfer radical polymerization (ATRP) process to cross-linkable fluorinated diblock copolymers and analyzing the data we are able to demonstrate the potential for developing films with different micro-structures for additional biological research. Applying the Dissipative Particle Dynamic (DPD) Method, Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) techniques to cross-linkable fluorinated diblock copolymers of (methyl methacrylate-co-hydroxyethyl methacrylate-co-butyl methacrylate)-b-2-(perfluoroalkyl)ethyl methacrylate (MMA-co-HEMA-co-BMA-b-FMA) we were able to analyze the structures and their relationships to the aggregation of various microstructure formations through the use of various solvents in the process. For the self-assembly of the cross-linkable diblock copolymer in solutions, the DPD simulation results are only in qualitative agreement with experimental data of aggregate morphologies and sizes. This suggests an improved approach to creating materials and methods necessary for studying microstructures in films used in other research areas. Our work examines whether using selective solvents can be easily extended to prepare aggregates with different morphologies, which is an effective shortcut to obtain films with different microstructures. DPD simulation can be considered as an adjunct to experiments and provides other valuable information for the experiment.

Preparation of New Anti-Slip Flooring Coatings: Hydrophobic MMA Floor Coatings

“…There are two medium bands at 654 and 708 cm -1 , resulting from a combination of rocking and wagging vibrations of -CF 2group. Moreover the peak at 750 cm -1 is due to the vibrations of -CF 3 group [12]. Accordingly, the FT-IR spectrum in Fig.…”

“…2) of the fluorine-containing methacrylic ester copolymers was recorded for confirmation of the structure of the copolymers. The peak of -OCH 3 at 3.56 ppm is due to the MMA units in the polymer chain and the wide band at 4.4 ppm is attributed to the -OCH 2 -group of Zonyl® TM [12]. Accordingly, the copolymer beads produced were made up of all the components viz.…”
