Summary: Initiated chemical vapor deposition (iCVD) is a dry method for designing organic and hybrid polymers, which provides conformal surface modification over intricate geometries. iCVD films can be grown with uniformity, high-purity, and pinhole-free properties, and can be applied onto flexible substrates, 2D materials, and liquids. The functional groups in iCVD polymers offer fine-tuning of surface energy, surface charge, and responsive behavior. iCVD polymers have various morphologies, such as nanostructured surfaces, nanoporosity, and shaped particles, and they are widely used in sensing, electronics, optics, electrochemical energy storage, and biotechnology applications.

Summary: This review focuses on the controlled release of pharmaceuticals and organic molecules using polymeric nanolayers grown by initiated chemical vapor deposition (iCVD). The technology allows for customization of reactors for various substrate geometries and can scale to large dimensions. iCVD layers can provide pinhole-free and ultrathin films, with rapid drug transport and mild conditions that avoid drug damage. Additionally, smart release is enabled by iCVD hydrogels responsive to pH, temperature, or light, and biodegradable iCVD layers have been demonstrated for drug release.

Summary: The demand for high-speed communication at high frequency has led to the development of low-dielectric polymer films. Aromatic polyimide (PI) is commonly used in flexible circuit boards due to its excellent properties, but its dielectric constant is relatively high for high-frequency communication. To address this, a hyper-crosslinked polymer (HCP) was synthesized and blended with PI to form all-organic HCP/PI composite films. The porous structure of HCP helps to reduce the dielectric constant of the PI matrix. By adjusting the HCP content, the dielectric constant of the composite films can be effectively lowered in the desired frequency range. This method is simple and can be applied to other organic component-filled PI systems.

Summary: This article discusses the issue of longitudinal decreasing film thickness and its solution, providing a theoretical model and experimental verification. By predicting the sticking coefficient curve, the actual homogeneous film thickness can be obtained and shown to be in good agreement with the prediction. Additionally, it is found that there is a maximum achievable homogeneous film thickness in the tube, which can be understood as the coating efficiency.

Summary: Combining chemical vapor deposition (CVD) with electrochemical polish (EP) operation is a promising method for producing performance-capable superconducting films. This study investigated the surface characteristics of CVD-grown and EP-polished niobium (Nb) films and found that EP effectively reduces surface roughness. The results suggest a dependence of EP on crystal orientation, providing insights for further optimization of film-based applications.

Summary: To achieve high-performance printed electronic devices, scalable and cost-effective printing of high-quality metallic electrodes with narrow gaps is desirable. This study demonstrates short channel transistors (<10 μm) with thin electrodes (<100-200 nm) fabricated by flexographic printing with nanoporous stamps, using single-wall carbon nanotubes as the network semiconductor. The measured performance of these transistors meets or exceeds those of previously reported SWCNT network transistors fabricated by alternative printing methods.
