新型CNT-PDMS光声换能器的制备及其声学性能与溶栓应用研究
Preparation of a novel CNT-PDMS photoacoustic transducer and study on its acoustic performance and thrombolysis application
摘要
Abstract
In response to the problem of uncontrollable thickness of the photoacoustic conversion layer and complex preparation process of traditional photoacoustic transducers,we proposed a preparation method of a novel carbon nanotube polydimethylsiloxane(CNT-PDMS)photoacoustic transducers.By systematically studying the relationship between the thickness of the CNT-PDMS trans-ducer photoacoustic conversion layer and the sound pressure intensity,the structural parameters of the conversion layer were optimized.The test result of acoustic performance showed that the sound pressure intensity increased with the increase of the conversion layer thickness,and reached peak at a laser pulse repetition frequency of 4 Hz and a conversion layer thickness of 83.4 μm.The result of the ultrasound thrombolysis experiment showed that under the action of ultrasound generated by the photoacoustic transducer,the rate of blood clot dissolution increased initially and then decreased with time.Thrombolysis of 5 min could reduce the weight of blood clots by about 40%.This study provides a new technological approach for the application of photoacoustic transducers in the medical field.关键词
