“… 49 After the grafting of the cationic polymer, the characteristic peak of the quaternized ammonium group at 1580 cm −1 newly appeared and the peaks corresponding to carbon–nitrogen and carbon–oxygen bonds in the grafted cationic polymer at 1220 and 1150 cm −1 , respectively, became very intense. 50 In the XRD patterns of GO and CPGO in Fig. S6, † the characteristic peak of GO (001) at 10° was not observed in CPGO, indicating that the amorphous structure was formed by grafting the cationic polymer.…”

Low dielectric constant (k) polymers with excellent comprehensive properties are useful materials in the microelectronics industry as matrix resins or encapsulation layers. With the inherent low polarization, high reactivity, good processability, and low cost, poly(dicyclopentadiene) (PDCPD) has received considerable attention as low‐k materials. However, its practical application is limited by the relatively high thermal expansion and k value. Herein, three norbornene‐functionalized polyhedral oligomeric silsesquioxanes (POSSs) with T8, T10, and T12 polyhedral cores are synthesized and employed for enhancing the dielectric and comprehensive properties of PDCPD via reactive blending. The results show that these POSSs have good compatibility with PDCPD matrix and nano‐dispersed POSSs particles could be obtained. As a result, the materials’ properties can be largely enhanced by varying the POSS content and POSS size. Especially, PT12N12‐40 (40 wt% of T12N12) shows the lowest k value (2.1) and coefficient of thermal expansion (63.4 ppm°C−1), highest glass transition temperature (202.5 °C), yield strength (78.0 MPa), and elastic modulus (2.36 GPa), along with excellent hydrophobicity. This study highlights a useful strategy to fabricate high‐performance low‐k polymer nanocomposites by using larger POSS and reactive blending, which provides useful materials for the future microelectronic industry and high frequency communication.

Siloxane coatings, characterized by their low surface energy and low elastic modulus, exhibit promising fouling-release properties. However, siloxane antifouling coatings still have certain limitations, which include low adhesion strength, poor antifouling performance, and weak mechanical properties. This review summarizes the modification methods of siloxane coatings, and focuses on three modification strategies: improving coating adhesion, static antifouling performance, and self-healing capabilities. This review provides insight into the preparation methods, enhancement mechanism and key critical issues of the three strategies. Additionally, potential research methods and materials that can further augment siloxane coating performance in the future were evaluated. Computational techniques such as molecular dynamics can aid researchers in understanding structural modification strategies at the molecular level. Photocatalytic antifouling agents are more suitable for future scientific and environmentally friendly design concepts. It is hope that this contribution provides valuable insights for researchers seeking a better understanding of advancements in siloxane antifouling coatings research and aids in developing novel solutions to address marine fouling issues.
