Combining Silk Sericin and Surface Micropatterns in Bacterial Cellulose Dressings to Control Fibrosis and Enhance Wound Healing

Abstract

Graphene has been hailed as a revolutionary membrane material because of its many alluring features and the ease in their tunability. In specific to gas separation industry, the exceptional molecular transport, the possibility of fabricating membranes having thickness at a nanoscale range and the robust lattice structure that can withstand to the rigorous perforation methods render graphene to stand ahead of its contemporary materials. Moreover, its broad chemical tolerance and high mechanical strength facilitate the mass-production of membranes possessing macroscopic dimensions and their subsequent long-term operation under harsh environments. In this concise review, we complied and discussed the progress of gas-separation performance of graphene-based membranes with a prime focus on recent advancements in scalability, functionalization/modification along with the new manufacturing processes including the budding approaches through synthetic chemistry. The strategies implemented, the factors that influenced the membranes'performance and the corresponding transport mechanisms were highlighted in detail. In the end, we outlined the daunting challenges facing by these graphene-based membranes in realization of their prospects as well as the proposed measures for alleviating them.

Promoting healing progress in polymer composites based on Diels‐Alder reaction by constructing silver bridges

“…Therefore, developing polymer materials with fast self‐healing ability is believed to be an efficiency way to address these issues. Inspired by nature, self‐healing polymer materials have been developed by various healing strategies and widely used in various fields to improve the safety, lifetime, energy efficiency, and environmental impact of artificial materials 30‐34 . However, at present, although self‐healing polymer materials can repair the damaged polymer materials, these self‐healing polymer composites still have faced a huge challenge that how to balance between high mechanical strength, healing efficiency and healing progress during the healing, especially by direct heating.…”
