Description
Technical field
The invention belongs to layer assembly self-supporting membrane technology field, be specifically related to a kind of based on laminated assembling technology preparation polymer double-decker self-supporting film and this film in the application that is used to prepare aspect the actuator.
Background technology
Through people's effort of more than ten years, the layer assembly film has been realized function and the potential application at aspects such as separation, catalysis, photoelectricity and surface modifications.But owing to the layer assembly film is deposited on the solid substrate usually, so the performance of layer assembly film is subjected to the influence of the substrate of depending on to a great extent.It is more convenient that the performance that the appearance of layer assembly self-supporting film is then studied multilayer film for people provides, and also widened the application of layer assembly film at aspects such as separation, catalysis, photoelectricity and sensors simultaneously.
The layer assembly polymer film can perception environmental stimuli generation volume variation, but owing to the layer assembly polymer film is deposited on the non deformable solid substrate usually, so the layer assembly polymer film never is subject to people's attention in the function aspect the actuator (actuators).The layer assembly polymer film is peeled off from substrate, just make the layer assembly polymer film not be subjected to the constraint of substrate for the response of environmental stimuli, can realize that assembling film produces the motion in two and three dimensions space for environmental stimuli, thereby carry out of the application of layer assembly polymer film at aspects such as actuator, micro-mechanical device even biologic-organs.
At present, although people prepared can perception various stimulations actuator, but can realize quick response, and the preparation of the physics that environmental stimuli is produced or the chemical energy actuator that is converted into mechanical movement efficiently but faces great challenge to stimulating.
