本研究成功製備出多樣式高導電奈米複合薄膜，此薄膜是藉由塗佈有機/無機奈米銀混成材料而來，其中奈米銀粒子可經由有機高分子型分散劑、無機奈米黏土及石墨氧化烯以非共價作用力吸附而達到分散及穩定，並進一步將分散液塗佈及加熱程序，最終可以獲得高導電之薄膜材料。
本論文分成三部份去探討:
第一部份 設計合成親水性及親油性高分子型分散劑穩定奈米銀粒子。親水性分 散劑使用有機分散劑-聚氧乙烯-醯亞胺（POE-imide）是由聚氧乙烯二胺和4,4-鄰苯二甲酸酐在不同溫度下化學反應合成接枝的醯胺和醯亞胺。親油性分散劑使用聚異丁烯-醯亞胺(PIB-imide-PIB)是由聚異丁烯丁二酸酐和聚氧乙烯二胺分別在不同溫度下化學反應合成接枝成醯胺和醯亞胺。在二甲基甲醯胺(DMF)的溶液系統中與硝酸銀進行化學反應的還原及穩定，藉由UV-visible與TEM觀察銀粒子的生成與粒子的穩定性及大小。最後兩款分散劑所合成的奈米銀粒子的粒徑分佈約為25nm，是相當好的一個穩定性及合成，對於之後親水或親油系統有一個選擇性。
第二部分 親水性分散劑與奈米雲母矽片的有機/無機混成分散劑穩定奈米銀粒子。奈米雲母矽片是通過層狀結構的雲母與聚胺離子交換反應所製備成的較親水性的脫層雲母，每一片的尺寸寬度約300-1000nm，厚度為1nm，表面陽離子當量數為 120 mequiv/100 g，而表面離子≡SiO–Na+與硝酸銀產生原位還原反應，讓奈米雲母矽片因為比表面積大且附有表面帶電性的一個特點來穩定奈米銀粒子，再加入親水性的有機分散劑-聚氧乙烯-醯亞胺（POE-imide）的一個混成，讓奈米銀粒子的一個吸附及穩定於奈米雲母矽片的含量有所提升，而所合成的奈米銀粒子有較窄的粒徑分佈約為20nm。此外，使用奈米銀粒子/POE-imide/奈米雲母矽片在重量比20：20：1時來製備的複合薄膜，通過溫度的控制下電阻值可低至4.5×10-2 /sq。
第三部份 親油性分散劑與石墨烯的有機/無機混成分散劑來穩定奈米銀粒子。使用商業化的氧化石墨烯作為分散劑，因為石墨烯本身由多芳香族所組成，所以較為親油，有較佳的導電性，而石墨烯表面所帶有的羧酸等氧化官能基來產生離子間的吸引來穩定奈米銀粒子於石墨烯的表面，同樣的添加我們所設計的親油分散劑-聚異丁烯-醯亞胺(PIB-imide-PIB)的一個混成讓石墨烯中的奈米銀粒子的有較佳的含量提升，氧化數越高的石墨烯所合成的奈米銀粒子也較為穩定，最後在奈米銀粒子/PIB-imide-PIB/石墨烯重量比20:20:1下奈米銀粒子的粒徑分佈約為16nm，製備的複合薄膜，通過溫度的控制下電阻值可低至5.6×10-2 /sq。
本研究目的是藉有機/無機的混成來提升奈米銀粒子在無機材料作為分散劑時的一個穩定性及含量的提升，對於之後可將有機/無機混合分散溶液塗佈及導電應用，而因基材的不同，可應用於柔性電子產品，可增加撓曲性這些奈米複合薄膜在未來可用於各種導電性設備的使用。

In this thesis, there are three parts describing the highly electrically conductive films were prepared by coating organic/inorganic nanohybrid solutions.
Part1: Design and Synthesis of hydrophilicity and Hydrophobicity polymer-dispersed stabilized silver nanoparticles (AgNPs). The Hydrophilicity organic dispersant, a polyoxyethylene-segmented imide (POE-imide), was synthesized from polyoxyethylene diamine and 4,4-oxidiphthalic anhydride through continuous amidation and imidation reactions. The Hydrophobicity organic dispersant, a polyisobutylene imide (PIB-imide-PIB) as the organic dispersant was synthesized via an imidation reaction of polyisobutylene-g-succinic anhydride (PIB-SA) and poly(oxyethylene)-diamine. The synthesized AgNPs had a narrow size distribution and a diameter of approximately 25 nm.
Part2: The polymeric dispersant (POE-imide) and exfoliated mica nanosheets (Mica) on which AgNPs had been dispersed in various components. The high-aspect-ratio Mica was prepared previously by the exfoliation of mica clay with a layered structure through an ion-exchange reaction with polyamine. The Mica was polydispersed such that each platelet was 300–1000 nm in width and 1 nm in thickness. These inorganic nanosheets possessed ionic charges in the form of ≡SiO–Na+ at 120 mequiv/100 g and were suitable for supporting AgNPs, the synthesized AgNPs had a narrow size distribution and a diameter of approximately 20 nm. Furthermore, a film with a sheet resistance as low as 4.5 × 10-2 /sq could be prepared by controlling the heating temperature and by using AgNPs/POE-imide/Mica in a weight ratio of 20:20:1.
Part3: The polymeric surfactant (PIB-imide-PIB) and graphene oxide nanosheets (GON) at various weight ratios. These organic/inorganic nanohybrid dispersants supported AgNPs in the process of the in situ reduction of silver nitrate. AgNPs at a narrow size distribution of ~16 nm in diameter. Moreover, the film exhibiting sheet resistance as low as 5.6 × 10−2 Ω/sq was prepared by controlling heating treatment.
Overall, the goal of this study was to employ the nanohybrid surfactants to improve the dispersion of AgNPs. Furthermore the highly electrically conductive films have great potential in electrically conducting device applications.
