Data for Heterotelechelic homopolymers mimicking high χ – ultralow N block copolymers with sub-2 nm domain size
Listed in figshare
Three fluorinated, hydrophobic initiators have been utilised for the synthesis of low molecular mass fluoro-poly(acrylic acid) heterotelechelic homopolymers to mimic high chi (χ)–low N diblock copolymers with ultrafine domains of sub-2 nm length scale.
Description
Polymers were obtained by a simple photoinduced copper(II)-mediated reversible-deactivation radical polymerisation (Cu-RDRP) affording low molecular mass (<3 kDa) and low dispersity (Đ = 1.04 – 1.21) homopolymers.
Heating/cooling ramps were performed on bulk samples (ca. 250 µm thick) to obtain thermodynamically stable nanomorpologies of lamellar (LAM) or hexagonally packed cylinders (HEX), as deduced by small-angle X-ray scattering (SAXS). Construction of the experimental phase diagram alongside a detailed theoretical model demonstrated typical rod-coil block copolymer phase behaviour for these fluoro-poly(acrylic acid) homopolymers, where the fluorinated initiator-derived segment acts as a rod and the poly(acrylic acid) as a coil.

This work reveals that these telechelic homopolymers mimic high χ-ultralow N diblock copolymers and enables reproducible targeting of nanomorphologies with incredibly small, tunable domain size.<br><br>--> Folder Structure: The files are organised by technique used for the characterisation of the final products. --> Software needed to open files according to technique used: for NMR files: ACD-LABS for MALDI-ToF files: Origin for GPC: Origin for SAXS: Origin for DSC: Origin See Readme file for protocols, parameters, details of equipment.
