Description
技术领域technical field
本发明涉及基于声音控制的形状记忆聚合物的驱动方法。The present invention relates to the actuation method of shape memory polymer based on sound control.
背景技术Background technique
形状记忆聚合物材料在一定条件作用下能够主动产生高达100％的大回复变形，因此在智能主动变形结构研究领域显示出巨大的应用潜力。同时，形状记忆聚合物在医学、航天、智能控制等领域广泛的应用前景，使得其受到了越来越多的重视。形状记忆聚合物按激励形式的不同可分为热致、电致、光致和溶液驱动等类型。在外界刺激下，可以从暂时的形状、颜色、尺寸、刚度或者应变回到初始的状态。Shape memory polymer materials can actively produce large recovery deformations up to 100% under certain conditions, so they show great application potential in the field of intelligent active deformation structure research. At the same time, the wide application prospects of shape memory polymers in medicine, aerospace, intelligent control and other fields have attracted more and more attention. Shape memory polymers can be divided into thermotropic, electrotropic, phototropic and solution-driven types according to different excitation forms. Under external stimuli, it can return to the initial state from a temporary shape, color, size, stiffness or strain.
合理的驱动方法对智能材料与结构的广泛应用起到了关键作用，不同的应用环境可以选择设计合理的方法进行有效的驱动。驱动方法的发展创新进一步拓宽了形状记忆聚合物材料的应用。由于激励形式简单、可回复形变量大和响应速度快等优点，使得热致型形状记忆聚合物是目前研究最为广泛和深入的。热致形状记忆聚合物的热--机械变形过程：在玻璃化转变温度Tg以上，对形状记忆聚合物(起始态)施加外力使其变形；在保持外界约束的前提下，使其降温至Tg以下一定温度，撤去外界约束，所赋变形能被长期保持下来(变形态)；当再次加热至玻璃化转变温度以上时，形状记忆聚合物能自动发生形状回复(回复态)。至此，完成“记忆起始态--固定变形态--恢复起始态”的变形循环。现有形状记忆聚合物驱动方法形式单调及操作复杂，驱动源要与形状记忆聚合物接触刺激，这些都限制了形状记忆聚合物的进一步应用；Reasonable driving methods play a key role in the wide application of smart materials and structures, and different application environments can choose rationally designed methods for effective driving. Innovations in the development of actuation methods have further broadened the applications of shape memory polymer materials. Due to the advantages of simple excitation form, large recoverable deformation and fast response speed, thermotropic shape memory polymers are currently the most widely and deeply researched. Thermal-mechanical deformation process of thermally induced shape memory polymer: Above the glass transition temperature Tg, an external force is applied to the shape memory polymer (initial state) to deform it; under the premise of maintaining external constraints, it is cooled to At a certain temperature below Tg, when the external constraints are removed, the endowed deformation can be maintained for a long time (deformation); when heated again above the glass transition temperature, the shape memory polymer can automatically undergo shape recovery (recovery state). So far, the transformation cycle of "memorizing the initial state--fixing the deformed form--recovering the initial state" is completed. The existing shape memory polymer driving methods are monotonous and complex in operation, and the driving source needs to be in contact with the shape memory polymer to stimulate, which limits the further application of shape memory polymers;

It is widely used in corridors, building corridors, courtyards and other places, and is an ideal novel green lighting switch in modern times. The sound-activated switch is generally composed of a microphone, sound signal amplification, half-wave rectification, light control, electronic switch, delay and AC switch circuit.

在传统声控开关的基础上对电路进行改进优化，得到与形状记忆聚合物材料变形回复相适应的声音控制系统。即一定的声音刺激后，电路接通，延时一定时间或者再次施加一定的声音刺激后电路断开。此过程中，形状记忆聚合物被加热至玻璃化转变温度以上，自动发生形状回复。实现了由声音控制驱动形状记忆聚合物材料变形回复过程。The circuit is improved and optimized on the basis of the traditional sound-activated switch, and the sound control system adapted to the deformation recovery of the shape-memory polymer material is obtained. That is, after a certain sound stimulation, the circuit is connected, and after a certain time delay or a certain sound stimulation is applied again, the circuit is disconnected. In this process, the shape memory polymer is heated above the glass transition temperature, and the shape recovery occurs automatically. The deformation recovery process of the shape memory polymer material driven by sound control is realized.

Based on this characteristic, the system can be used in various lock release mechanisms and other sound control or sound actuation devices.
