We report on the synthesis and the mechanical characterization of an alginate-collagen fibril composite hydrogel. Native type I collagen fibrils were used to synthesize the fibrous composite hydrogel. We characterized the mechanical properties of the fabricated fibrous hydrogel using tensile testing; rheometry and atomic force microscope (AFM)-based nanoindentation experiments. The results show that addition of type I collagen fibrils improves the rheological and indentation properties of the hydrogel.
我们报道了一种藻酸盐-胶原纤维复合水凝胶的合成及力学特性。使用天然I型胶原纤维来合成纤维复合水凝胶。我们通过拉伸测试、流变学测量以及基于原子力显微镜（AFM）的纳米压痕实验对制备的纤维水凝胶的力学性能进行了表征。结果表明，添加I型胶原纤维可改善水凝胶的流变学和压痕性能。
