“…As shown in Figure 6, four distinct and strong absorption peaks were observed for the DVS-BCB layer. The prominent features in the FT-IR spectra are Si-CH 3 stretch (≈1255 cm −1 ), Si-O-Si stretch (≈1040 cm −1 ), Si-O bending (≈830 cm −1 ), and Si-CH 3 bending (≈780 cm −1 ), which is consistent with the results of typical DVS-BCB bonding [36,37]. With these features, we can observe the degree of Si-O-Si bonding and Si-CH 3 bonding.…”

Divinylsiloxane-bis-benzocyclobutene (DVS-BCB) has attracted significant attention as an intermediate bonding material, owing to its excellent properties. However, its applications are limited, due to damage to peripheral devices at high curing temperatures and unoptimized compressive pressure. Therefore, it is necessary to explore the compressive pressure condition for DVS-BCB bonding. This study demonstrates an optimization process for void-free DVS-BCB bonding. The process for obtaining void-free DVS-BCB bonding is a vacuum condition of 0.03 Torr, compressive pressure of 0.6 N/mm2, and curing temperature of 250 °C for 1 h. Herein, we define two factors affecting the DVS-BCB bonding quality through the DVS-BCB bonding mechanism. For strong DVS-BCB bonding, void-free and high-density chemical bonds are required. Therefore, we observed the DVS-BCB bonding under various compressive pressure conditions at a relatively low temperature (250 °C). The presence of voids and high-density crosslinking density was examined through near-infrared confocal laser microscopy and Fourier-transform infrared microscopy. We also evaluated the adhesion of the DVS-BCB bonding, using a universal testing machine. The results suggest that the good adhesion with no voids and high crosslinking density was obtained at the compressive pressure condition of 0.6 N/mm2. We believe that the proposed process will be of great significance for applications in semiconductor and device packaging technologies.

“…To validate bonding structure changes with SiNPs and AgNWs, Fourier transform infrared (FTIR) spectroscopy for the Si/5-P electrode, Si/5-P/AgNW electrode, and AgNW is performed (Figure c). The peaks of the Si–O–Si bond of SiNP at 1030 cm –1 and the CC bond of the PEDOT chain at 1635 cm –1 are verified for both Si/5-P and Si/5-P/AgNW electrodes. , On the contrary, the characteristic peak of Ag–O at 582 cm –1 appears only for the Si/5-P/AgNW electrode, which reconfirms the existence of AgNW networks in the electrode …”

Silicon (Si) anodes in lithium-ion batteries (LIBs) suffer from huge volume changes that lead to a rapid capacity decrease and short cycle life. A conductive binder can be a key factor to overcome this issue, maintaining continuous electron paths under pulverization of Si. Herein, composites of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) and poly(vinyl alcohol) (PVA) are augmented with poly(ethylene glycol) (PEG) and poly(ethylene oxide) (PEO) as a binder for Si anodes, which forms hierarchical structures due to different chain lengths of PEG and PEO. The integration of PEG and PEO imparts higher electrical conductivity (∼40%) and stretchability (∼60%) through densely spread hydrogen bonding and crosslinking, compared to conductive polymer binders with PEO or PEG. Further, a silver nanowire (AgNW) network combined with the polymer binder supplies an effective three-dimensional (3D) electrical path, sufficient void space to buffer the volume changes, and highly adhesive interaction with the current collector. The fabricated Si anode demonstrates a higher specific capacity of 1066 mAh g −1 at 0.8 A g −1 after 100 cycles and improved rate capability.

“…Unlike the uncoated PET (control) spectra, the spectra of the Si-Al film showed major peaks corresponding to Si−CH 3 (1270 cm −1 ), Si−CH 2 (770 cm −1 ), and Si−O−Si (Si−O−Al) stretching (1040 cm −1 ), and OH (Si−OH, Al−OH) stretching (3200−3550 cm −1 ). 23,34 After CV modification, new peaks corresponding to the C−N stretching of aromatic tertiary amine (1361 cm −1 ), CV ring vibration (1590 cm −1 ), and C-benzene ring stretching (1170 cm −1 ) were observed, 35,36 indicating the presence of CV. In addition, a red shift occurred in the OH stretching band (Figure 2b).…”

Healthcare-associated infections can occur and spread through direct contact with contaminated fomites in a hospital, such as mobile phones, tablets, computer keyboards, doorknobs, and other surfaces. Herein, this study shows a transparent, robust, and visible light-activated antibacterial surface based on hydrogen bonds between a transparent silica-alumina (Si-Al) sol−gel and a visible light-activated photosensitizer, such as crystal violet (CV). The study of the bonding mechanisms revealed that hydrogen bonding predominantly occurs between the N of CV and Al-OH. Apart from CV, Si-Al can be combined with a variety of dyes, highlighting its potential for wide application. The Si-Al@CV film selectively generates singlet oxygen using ambient visible light, triggering potent photochemical antibacterial performance against Gram-positive and Gram-negative bacteria. Additionally, the Si-Al@CV film is stable even after mechanical stability tests such as tape adhesion, scratch, bending, and water immersion. In vitro cytotoxicity tests using C2C12 myoblast cells showed that the Si-Al@CV film is a biocompatible material. This work suggests a new approach for designing a transparent and robust touchscreen surface with photochemical antibacterial capability against healthcareassociated infections.
