In high‐frequency printed circuit boards (PCBs), there is an inherent contradiction between minimizing signal loss and maximizing adhesion strength. To tackle this issue, this work presents a simple approach by developing an enhanced interlayer through a two‐step process involving anodization/APTES (3‐aminopropyltriethoxysilane) treatment. The anodization yields micro/nano oxide structures with low surface roughness, thereby reducing the skin effect. One side of the enhanced interlayer is mechanically anchored and chemically bonded to copper foils, while the other side is coupled with bismaleimide/triazine‐based resins (BT resins), significantly augmenting the adhesion strength. Eight‐layer PCBs manufactured employing this method exhibit an insertion loss of −1.3553 dB in−1 at 32 GHz. Compared to two conventional brown oxide methods, the insertion loss is reduced by 7.80% and 3.24%, respectively, with a more substantial reduction observed at higher frequencies. The peel strength of samples ranges from 0.554 to 0.589 N mm−1, demonstrating maximum enhancements of 34.78% and 164.13% in comparison to the two brown oxide methods, respectively. Moreover, eight‐layer PCBs undergo lead‐free reflow soldering tests, solder float tests, and thermal fatigue tests without encountering any failures. Consequently, the proposed method holds significant practical significance in addressing the challenge associated with low signal loss and high adhesion strength in high‐frequency PCBs.

“…Another research by Xiaonan Zhao et al looked at how well MMMs with various filler contents separated pure gases from a CO 2 /CH 4 gas mixture 11 . Comparing MMMs based on Pebax and MMMs based on APDS‐modified SAPO‐34, those containing 8 wt% of the modified SAPO‐34 showed the highest CO 2 /CH 4 selectivity and CO 2 permeability of approximately 34.7 and 137 Barrer respectively.…”

Gas separation process is an effective method for capturing and removing CO2 from post‐combustion flue gases. Due to their various essential properties such as ability to improve process efficiency, polymeric membranes are known to dominate the market. Trade‐off between gas permeability and selectivity through membranes limits their separation performance. In this study, solution casting cum phase separation method was utilized to create polyethersulfone‐based composite membranes doped with carbon nanotubes (CNTs) and silico aluminophosphate (SAPO‐34) as nanofiller materials. Membrane properties were then examined by performing gas permeation test, chemical structural analysis and optical microscopy. While enhancing membranes CO2 permeance, SAPO‐34 and CNTs mixture improved their CO2/N2 selectivity. By carefully adjusting membrane casting factors such as filler loadings. Using Taguchi statistical analysis, their carbon capture efficiency was improved. The improved mixed‐matrix membrane with loading of 5 wt% CNTs and 10 wt% SAPO‐34 in PES showed highly promising separation performance with a CO2 permeability of 319 Barrer and an ideal CO2/N2 selectivity of 12, both of which are within the 2008 Robeson upper bound. A better mixed‐matrix membrane with outstanding CO2/N2 selectivity and CO2 permeability was produced as a result of the synergistic effect of adding two types of fillers in optimized loading.
