Nicolet 5700

The latex particles size data of latex particles were obtained from dynamic light scattering on a Malvern particle size (PSD; Nano-ZS90, Malvern Panalytical, Almelo, The Netherlands).
GPC (gel permeation chromatography) analysis was performed in THF (tetrahydrofuran) (1.0 mL/min, 30 °C) while using a Viscotek TDA302 (GPC; Viscotek TDA302, Malvern Panalytical, Almelo, The Netherlands) with a WL. M GPC solvent/sample module.
FTIR (Fourier transform infrared spectroscopy) analyses were obtained from Nicolet 5700 (FTIR; Nicolet 5700, Thermo Electron Co., Waltham, MA, USA) within the frequency range of 650–4000 cm⁻¹ by KBr pellets technique and a resolution of 4 cm⁻¹ was used to analyze the chemical structure of the dried latex particles.

UV-1800 (SHIMADZU Co., Japan) was used to measure the UV-vis absorbance of TFB films, and Nicolet5700 (Thermo electron Co., USA) was used to measure the FT-IR absorbance peaks of TFB films. M6100 OLED I-V-L Test System (McScience Co., Korea) was used to measure the current - voltage - luminance (IVL) and current density - voltage (CD - V) characteristics of QLEDs and HODs, respectively. Agilent 4284a Precision LCR meter (Agilent technologies, USA) was used to measure the capacitance - frequency (C-f) and capacitance - voltage (C-V) characteristics of the HODs.

The morphologies of bare 316L SS, PTMC and PTMC-E5 samples were observed by scanning electron microscopy (SEM, JSM-7001F, Japan Electron Optics Laboratory Co., Ltd., Tokyo, Japan), and the surface chemical composition of PTMC-E5 was examined using Fourier transform infrared spectrometry (FTIR, NICOLET 5700, Thermo Electron Corporation, Waltham, MA, USA) with reflectance mode and X-ray photoelectron spectroscopy (XPS, K-Alpha, Thermo Electron Limited, Winsford, UK) [29 (link),30 (link),31 (link)]. The wettability of the bare 316L SS, PTMC and PTMC-E5 sample surfaces was assessed by water and blood contact angle measurement (DSA 100, Krüss GmbH, Hamburg, Germany) [32 (link)]: the samples were first dried and then fixed to a glass slide. A droplet of dH₂O was added to the surface to detect contact angle using a horizontal microscope. For each sample, the mean value of the contact angle was calculated from at least three individual measurements taken at different locations on the samples examined. The drug-eluting portion of the estradiol was also investigated, as described elsewhere [16 (link)].
