Composite colloidal gels are formed by the pH-induced electrostatic assembly of silica and gelatin nanoparticles. These injectable and moldable colloidal gels are able to withstand substantial compressive and tensile loads, and exhibit a remarkable self-healing efficiency. This study provides new, critical insight into the structural and mechanical properties of composite colloidal gels and opens up new avenues for practical application of colloidal gels.
复合胶体凝胶是通过 pH 诱导的二氧化硅和明胶纳米粒子的静电组装形成的。这些可注射和可模塑的胶体凝胶能够承受很大的压缩和拉伸载荷，并表现出显著的自修复效率。本研究为复合胶体凝胶的结构和力学性能提供了新的、关键的见解，并为胶体凝胶的实际应用开辟了新的途径。
