中文摘要 | 聲波感測器可對微量氣體作快速、靈敏、即時的偵檢。感測器偵檢氣體通常選用靈敏、快速可逆回應、且具有再現性的高分子吸收膜材。吸附效果影響感測器的靈敏度與選擇性,其參數是由膜材與氣體間的作用力(如凡德瓦爾力、極化、氫鍵)及膜材高分子的玻璃轉換溫度高低等決定。在本文中,同時也介紹膜材的種類、披覆方法及其在軍事用途上的應用實例。 |
英文摘要 | Acoustic wave sensors provide a convenient, sensitive and real-time method to detect and identify trace gases. The sorbent phases with sensitivity, rapid reversible responses, and reproducibility were potentially used for sensors and sensor arrays. The gas sorption by polymer films contributing to the sensitivity and selectivity of sensors would be not only related to fundamental interactions such as van der Waals interactions, polarity, and hydrogen bonding between the vapor molecules and the sorbent phase, but also to the physical properties of the sorbent polymers such as the glass transition temperature. This report reviews the kinds and coating methods of the SAW sorbents, additionally their practical application examples for military chemical detection. |
