The Material Science of Biomimetic Soft Network Composites

大自然将硬而强的胶原蛋白纤维交织在蛋白多糖的弱聚合物基质中，形成软组织，具有出色的机械耐用性和生物特性。我们融合了源于天然软组织结构的仿生设计策略和一种名为熔融电写(MEW)的新型添加剂制造技术，以制造先进的仿生软网络复合材料(BSNC)。SNCs由弱聚合物基质和纳米级印刷的MEW增强纤维相组成，包含模拟自然组织结构的图案。先进的计算工具被应用于SNC的合理设计，同时减少了与实验工作相关的成本和时间。

Nature combines stiff and strong collagen fibres intertwined within a weak polymer matrix of proteoglycans into soft tissues with outstanding mechanical durability and biological properties. We converge a biomimetic design strategy inspired in the architecture of natural soft tissues and a novel additive manufacturing technology termed melt electrowriting (MEW) to manufacture advanced biomimetic soft network composites (BSNC). The SNCs are composed of a weak polymer matrix and a MEW reinforcing fibrous phase printed at the nanometre scale, containing patterns mimicking the natural tissue architectures. Advanced computational tools are applied for the rational design of the SNC while reducing costs and times associated to experimental work.
