本研究針對聚苯胺(PANI)導電態變化進行近一步的探討，由於聚苯胺在酸性環境下因為氫離子的摻雜效應進一步改變其導電態，以此原理發想，在過去已成功得到質子射束對聚苯胺進行相似的摻雜效應，並透過光譜檢測等方式來說明質子摻雜與酸性摻雜的相似性，此結論打開了聚苯胺在不同產業的發展淺力。
質子射束在進入材料後隨著動能損失到一定程度，會發生「布拉格峰效應」釋放其剩餘的動量並停留在材料內，利用此特性使質子與EB態聚苯胺接觸並摻雜。但質子射束與聚苯胺的交互作用除了摻雜效應還伴隨著熱交聯與炭化等因素，這些因素對聚苯胺的導電率也具有一定程度的影響。
質子射束的通量率與照射時間也在本次研究中進行探討，為找到較有效率的質子射束摻雜條件，設計不同的變因進行實驗，且透過光譜分析來確定摻雜效應的發生，並將質子摻雜所需的照射時間由50分鐘減少至15分鐘，提高質子摻雜效率。
為了瞭解聚苯胺在質子射束照射下的導電率的變化，我們設計以矽基材為主的聚苯胺質子感測器，以智慧型歐姆計去紀錄聚苯胺與質子射束作用下的電阻變化圖，透過電阻的變化曲線可得到質子摻雜對聚苯胺的導電率影響。
為近一步的了解質子射束對聚苯胺的影響，使用XPS、AFM、SEM、SIMS、四點探針、UV-vis等儀器來分析照射前與照射後樣品的變化，並且分析其中的物理機制。從XPS N1s的分析中近一步解釋帶電官能基在比例變化上與樣品摻雜程度的關聯。

In this research we further study on the change of the conductivity of polyaniline (PANI). Because polyaniline changes its conductive state due to the doping effect of hydrogen ions in an acidic environment, based on this principle, it has successfully obtained the proton beam performs a similar doping effect on polyaniline and demonstrates the similarity between proton doping and acid doping through spectroscopic detection. This conclusion opens up the development of polyaniline in different industries.
After the proton beam enters the material, the kinetic energy is lost to a certain extent, and the "Bragg peak effect" will occur to release all its energy and stay in the material. This feature makes the protons contact and dope with the EB state polyaniline. However, the interaction between the proton beam and polyaniline is accompanied by factors such as thermal crosslinking and carbonization in addition to the doping effect. These factors also have a certain degree of influence on the conductivity of polyaniline.
The energy, flux rate and irradiation time of the proton beam are also discussed in this study. In order to find more efficient proton beam doping conditions, different variables are designed to conduct experiments, and the doping effect is determined through spectral analysis. The irradiation time required for proton doping is reduced by 70%, and the efficiency is improved.
In order to understand the changes in the conductivity of polyaniline under the irradiation of proton beams, we designed a polyaniline proton sensor based on glass, use a smart ohmmeter to record the resistance change graph under the action of polyaniline and proton beams. Through the resistance change curve, the effect of proton doping on the conductivity of polyaniline can be obtained.
In order to further understand the effect of proton beam on polyaniline, XPS, AFM, SEM, SIMS, four-point probe, UV-vis and other instruments are used to analyze the changes of samples before and after irradiation, and analyze the physical mechanism. . From the analysis of XPS N1s, explain the relationship between the ratio of imine and imine ions and the conductivity of the sample.
