### Characterization  
Fourier-transformed infrared (FTIR) spectra were collected using a Thermo Nicolet Avatar 370-FTIR spectrometer (Thermo Scientific, Waltham, MA, USA) with an attenuated total reflectance (ATR) accessory. The spectra were obtained in the 400-4000 cm\({}^{-1}\) spectral region, with 64 scans, and 4 cm\({}^{-1}\) resolution. Proton nuclear magnetic resonance (\({}^{1}\)H NMR) spectra were obtained on an Agilent MR400 DD2 spectrometer (Santa Clara, CA, USA) operating at 400 MHz. Raman spectra were collected on a DXR Raman Microscope (Thermo Scientific, Waltham, MA, USA) at a laser power of 1 mW.  
Gas-chromatography/mass spectrometry (GC-MS) analyses were completed on a Shimadzu GC-17A gas chromatograph equipped with a mass spectrometer detector Shimadzu GCMS-QP5050A (Kyoto, Japan) using a 30 m Kxi-5 ms column (Restek, Bellefonte, PA, USA) with an internal diameter of 0.25 mm and a film thickness of 0.25 \(\upmu\)m. Samples were dissolved in acetone, leading to an approximate concentration of 5% (_v/v_). Helium was used as the carrier gas at a total (column + split) flow rate of 10 mL/min. The temperature was initially held at 70 \({}^{\circ}\)C for 2 min, then increased to 300 \({}^{\circ}\)C at a heating rate of 15 \({}^{\circ}\)C/min, and finally held at 300 \({}^{\circ}\)C for 13 min.  
Dielectric analysis (DEA) measurements were completed on an Epsilon DEA 230/1 cure monitor (Netzsch Instruments North America LLC, Burlington, MA, USA). Differential scanning calorimetry (DSC) studies were conducted on a Q250 DSC instrument from TA Instruments (New Castle, DE, USA). 5-10 mg of sample were heated from -30 to 200 \({}^{\circ}\)C at a rate of 10 \({}^{\circ}\)C/min under N\({}_{2}\) atmosphere in aluminum hermetic pans.  
Static and dynamic contact angles were measured using a goniometer (Rame-hart, Succasunna, NJ, USA) equipped with an automatic drop dispenser. For the static contact angle measurements, 2.0 \(\upmu\)L of water were dispensed onto a flat surface of the sample and the contact angle was measured every 30 s for a total of 10 measurements, and repeated for a total of three trials. The average angle from the three trials are reported. For the dynamic contact angle, measurements were generated by slowly enlarging the droplet size (advancing contact angle, \(\uptheta_{\mathrm{a}}\)) and then retracting it (receding contact angle, \(\uptheta_{\mathrm{r}}\)). For each expanding or retraction step, 0.25 \(\upmu\)L of water was used.  
Water absorption experiments were conducted by weighing fully cured samples at their dry state (\(W_{\mathrm{d}}\)), and then submerging them in water for 24 h. After 24 h, the samples were removed from water and their wet weight (\(W_{\mathrm{w}}\)) was recorded after gently drying the excess water with a kimwipe. The morphology analyses were completed on a JSM-760F field emission scanning electron microscope (SEM) (JEOL, Peabody, MA, USA), using an accelerating voltage of 1.0 kV, secondary electron imaging (SEI) and lower detector scanning (LEI) modes, and an emission current of approximately 81 mA. All samples were sputter-coated with gold prior to imaging.  
Thermal degradation profiles were obtained on a Q50 thermal gravimetric analyzer (TA Instruments) using samples of approximately 10 mg. The experiments were run under air, from 30 to 500 \({}^{\circ}\)C, with a heating rate of 10 \({}^{\circ}\)C/min. Thermo-mechanical properties were assessed on a Q800 DMA (TA Instruments) using a three-point bending fixture with 15 mm gap. Rectangular samples (1.5 mm \(\times\) 10.0 mm \(\times\) 17.0 mm--thickness \(\times\) width \(\times\) length) were cut and subjected to an iso-strain experiment with an amplitude of 14 \(\upmu\)m. The temperature was increased from -60 to 150 \({}^{\circ}\)C at a heating rate of 3 \({}^{\circ}\)C/min.
