Although RFID systems have been successfully applied in our daily lives, but it’s limited range of applications. Some scholars used of polymer blending Method to Polyvinyl Alcohol (PVA) as a mixed-adhesive absorbent was prepared with the absorption of EMW performance of PVA composite films. The goal of this report is to examine and characterize the small world phenomenon in the patent citations network by analyzing the data of RFID patents. The results suggest that the patent citation network can indeed be characterized as “small world”. Additionally, the patent citation network resembles the power-law connectivity distribution and exhibits preferential connectivity behavior. In other words, a few key patents have a great many more connections than the majority of patents with few connections. Furthermore, the patents of high betweenness centrality were identified. It is found that eighty-one percent of the patent citation activities have relations with the patents of high betweenness centrality. The result of this analysis will provide a specific way for managers to identify key patents, to map their own patent deployment and to derive insight into the best ways to navigate within such networks. Keywords: small world network, radio frequency identification, patent citation, betweenness centrality
