Synthesis and characterization of a new fluorinated macroinitiator and its diblock copolymer by AGET ATRP

Synthesis and properties of cross-linkable block copolymer end-capped with 2, 2, 3, 4, 4, 4-hexafluorobutyl methacrylate

“…Firstly, during the film formation process (for the measurement of surface properties) the fluorinated segments in the systems were very easy to enrich on the surface of the coated film. The enrichment of fluorine had been reported in our previous study [4], and similar conclusion had also been mentioned in other literatures [31,32].The second can be due to the structure of the HFMA-PIBMA-b-PTMSPMA. It was found that the polymer end-capped fluorinated group had the special push-me/pull-you architectures, the lowenergy functional groups in the polymer could be pulled to the air-polymer interface and the high-energy functional groups could be pulled to the glass-polymer interface [22,33].Thus, the efficiency of fluorine could be maximized by anchoring the fluorinated group at the end of the molecular chain.…”

“…Block copolymers have unique microphase separation, which make them have broad application including dispersants, compatibilizers, surfactants, emulsifiers, foam stabilizers and templates for functional materials [1][2][3][4][5]. Besides the common properties of block copolymers, cross-linkable block copolymers presented more advantages.…”

Synthesis and comparison of two poly (methyl methacrylate-b-3-(trimethoxysilyl)propyl methacrylate)/SiO 2 hybrids by “grafting-to” approach

“…It is found that the migrating of F-Br onto the film could exhibit the film with low wettability and high stable surface. This is also proved by other fluorinated initiators such as poly 2,2,3,4,4,4-hexafluorobutyl methacrylate-Br (PHFMA-Br) [33], 1,1-dihydroperfluorooctyl methacrylate-Br (FOMA-Br) [34], 2,2,2-trifluoroethyl methacrylate-Br (TFEMA-Br) [35], and 2,3,5,6-tetrafluorophenyl methacrylate-Br (TFPM-Br) [36]. Actually, the fluorinated initiators could perform dual-function for initiating effectively ATRP and introducing the fluorine-containing group into the block polymers.…”

Methods of controlled radical polymerization for the synthesis of polymer brushes

“…However, such proce dures are successfully used in the methodology of heterophase ATRP; that is, when polymerization is conducted in a miniemulsion [77,78]. Note that the modifications of ATRP based on the use of electron transfer to regenerate the activator have an impor tant advantage because initiators introduced into the system cannot initiate polymerization by them selves; therefore, they are suitable for the synthesis of linear block copolymers [89,90] and copolymers with complex architectures, such as polymer brushes [91], and for controlled synthesis in organic media and heterogeneous systems, e.g., in miniemulsions [91][92][93][94].…”
