title: Data from: Electrostatic complexation of conjugated and bottlebrush polyelectrolytes forms printable conductive inks

description: Electrostatic complexation enables blending of otherwise immiscible
 polymers by liquid–liquid phase separation, forming a polymer-rich phase
 suitable for processing. We explored design rules for processable
 complexes using electrically conductive conjugated polyelectrolytes (CPEs)
 and mechanically tunable bottlebrush polyelectrolytes (BPEs). Sulfonated
 polythiophene and self-doped sulfonated PEDOT were examined to study how
 charge fraction influences compatibilization, printability, and
 properties. The resulting CPE: BPE complexes exhibited rheology suitable
 for direct ink writing into thick patterned structures. Upon drying, they
 combined electrical conductivity with elasticity and adhesiveness,
 enabling applications in soft, thick, semiconducting materials.

 methods accompanied to this dataset** **Nuclear magnetic resonance (NMR)**
 All bottlebrush polymer ^1^H NMR spectra were collected using a Varian
 Unity Inova AS600 600 MHz equipped with a 5 mm Varian triple resonance
 ^1^H/^13^C/^15^N inverse detection probe with *z*-axis pulsed field
 gradient (PFG). All linear polymer ^1^H NMR spectra were collected using a
 600MHz SB Varian VNMRS equipped with a double resonance Broadband Probe
 Head 600 DB Auto X. Small molecule ^1^H, ^13^C NMR, and 2D-NMR were
 collected using a **Bruker Avance NEO 500 MHz** equipped with a CryoProbe
 Prodigy BBO probe with *z*-axis PFG. **UV-Vis spectroscopy**
 **Solutions:** The targeted concentrations of polyelectrolytes were
 prepared using molarity defined by mols of charged repeating units (Q =
 0.8 for SPEDOT and 0.6 for SP3HT and BPE). Absorbance of the solutions
 were measured through a Cary UV-Vis spectrophotometer (Agilent). **Solid
 samples for spectroscopy:** PEDOT-3S-Na:BPE was extruded and smeared on
 top of a quartz substrate. The reflectance of the dried solid was measured
 through an UV3600 UV-Vis-NIR spectrometer (Shimadzu). The absorbance was
 calculated by the Kubelka-Munk transformation function of the diffuse
 reflectance spectra. **Rheology** A strain-controlled ARES-G2 rheometer
 equipped with an Advanced Peltier System (APS) and a solvent trap from TA
 Instruments was used to investigate the shear stress relaxation and linear
 viscoelastic properties of the blend. 8-mm stainless steel plates were
 used for all measurements. Pieces of paper soaked with water and THF were
 carefully placed inside the solvent trap to provide a saturated solvent
 environment to the material during testing to best minimize solvent
 evaporation. All measurements were done at room temperature using the same
 geometry and setup. **Grazing-incident wide angle X-ray scattering
 (GIWAXS)** Identical films for UV-Vis-NIR measurements were brought on
 beamline 11–3 at the Stanford Synchrotron Radiation Lightsource (SSRL).
 LaB6 was used as the calibrant for the beam center and a
 sample-to-detector distance of 315 mm was used. 2-D GIWAXS scattering
 images were collected using 2D Rayonix MX225 CCD area detector at an
 incidence angle of 0.10° with 30 s exposure times. The samples were kept
 under helium during X-ray exposure to minimize sample degradation and
 scattering from oxygen. The collected data was processed using Nika, a 2-D
 data reduction macro on Igor Pro using established procedures. ### Files
