主 题：self-healing nanosilica hydrogels anisotropic conductivity
摘 要：Soft nano electronic materials based on conductive hydrogels have attracted considerable attention due to their exceptional *** deposition and poor interface compatibility often diminish the mechanical strength and electron transport capabilities of the conductive *** damage can severely impact the performance of the conductive hydrogel and can even damage electronic devices based on the conductive *** the current study,a transparent nano-silica hydrogel is prepared by employing an extremely easy-to-operate *** approach can preclude the deposition of particles via strong mechanical *** addition,controlling the concentration of the reaction interface makes the hydrogel grow along the mechanical force in the direction with a special directional hole structure *** hydrogel is transparent,showing excellent self-healing properties—it can self-heal within 15 ***,the hydrogel after self-healing maintains its ***,it has excellent mechanical properties and can be stretched in *** to 1,200%of the original length,the tensile strength of the gel spline can reach 7 *** viscosity of the hydrogel can reach 1.67×10^(8)(MPs).In addition,a large amount of Na+in this hydrogel endow it a conductivity of 389 ps/*** conductivity of this hydrogel is adjustable result from the special pore ***,the difference between the horizontal and vertical conductivity of the same sample can reach 3-4 times,thus this hydrogel can be used in the field of nano conductive materials.
