Abstract: This article mainly Research of metal nanoparticles and precursor solution two-phase anisotropy of micro-nano structure thermal contraction.Here Is the starting point of this research : 1) Metal nanoparticles and precursor solution form of slurry at high temperature sintering due to evaporation of moisture in the pulp and the spread of the nanoparticles filled gap will make the slurry produces a certain percentage of the contract. 2)Electric and magnetic fields are the direction of the field, in particular the specific according to directional environment also have directional growth of crystals, electric field or magnetic field of metal nanoparticles and the influence of the direction of the thermal contraction of the precursor solution possible .
The article introduces the research progress of metal nanoparticles and discusses the forming of nano particles and precursor solution heat shrinkable properties of pulp.Electric field is put forward to form slurry heat shrinkable likely impact in one direction ,And use the multiphysics modeling software comsol simulation .
Keywords: Metal nanoparticles ; The precursor solution ;The electric field ; The anisotropic shrinkage .
