Abstract

The invention discloses oil/water double-layer gel with a high interfacial effect and a preparation method of the oil/water double-layer gel. The preparation method comprises the steps that (1) a water-soluble polymerizable monomer, an initiator I and a crosslinking agent I are dissolved into water to obtain a water phase reaction solution; (2) an oil-soluble polymerizable monomer, an initiator II, micro-nano particles modified by a silane coupling agent and a crosslinking agent are mixed to obtain an oil phase reaction solution; and (3) the water phase reaction solution and the oil phase reaction solution are sequentially injected into a mold, and statically placed for 2-24 h to obtain the oil/water double-layer gel. The invention further discloses application of the oil/water double-layer gel to the preparation of intelligent actuators and petroleum/natural gas pipelines. According to the oil/water double-layer gel, a 'one-pot method' is adopted to prepare the oil/water double-layergel with the high interfacial effect and high mechanical strength, multiple stimuli responsive properties can further be obtained by regulating the kinds of the water-soluble polymerizable monomer andthe oil-soluble polymerizable monomer, and the oil/water double-layer gel can be used for designing multiple stimuli responsive soft actuators and sensing elements.

Description

technical field [0001] The invention belongs to the technical field of polymer gel, and in particular relates to a preparation method and application of an oil / water double-layer gel with strong interfacial interaction. Background technique [0002] Stimuli-responsive hydrogels exhibit special shape or volume changes in response to external environmental changes (such as temperature, pH, light, electric field, humidity, and ions, etc.). Among them, stimuli-responsive hydrogels that can achieve bending deformation have great application prospects in the fields of intelligent actuators, sensors, and tissue engineering. There is a difference in swelling / shrinkage between the upper and lower layers of the hydrogel, thus exhibiting the overall bending deformation of the hydrogel. [0003] However, the low modulus of hydrogels makes the bilayer structure more limited in terms of deformation actuation (mainly reflected in mechanical properties). Combining mutually incompatible oi...
