Polyimide (PI) nanocomposites with both enhanced thermal conductivity and dimensional stability were achieved by incorporating glycidyl methacrylate‐grafted graphene oxide (g‐GO) in the PI matrix. The PI/g‐GO nanocomposites exhibited linear enhancement in thermal conductivity when the amount of incorporated g‐GO was less than 10 wt%. With the addition of 10 wt% of g‐GO to PI (PI/g‐GO‐10), the thermal conductivity increased to 0.81 W m−1 K−1 compared to 0.13 W m−1 K−1 for pure PI. Moreover, the PI/g‐GO‐10 composite exhibited a low coefficient of thermal expansion (CTE) of 29 ppm °C−1. The values of CTE and thermal conductivity continuously decreased and increased, respectively, as the g‐GO content increased to 20 wt%. Combined with excellent thermal stability and high mechanical strength, the highly thermally conducting PI/g‐GO‐10 nanocomposite is a potential substrate material for modern flexible printed circuits requiring efficient heat transfer capability.
The global online shopping market has exhibited consistent growth, exceeding an annual average growth rate of 10% from 2006 to 2010; however, the online shopping market in Taiwan demonstrated an astounding growth rate, surpassing 35% during the same period. In the current competitive and rapidly expanding market environment, shopping website providers must establish effective methods for measuring and improving service quality to increase customer satisfaction levels. In this study, four service quality dimensions of the e-core service quality scale (E-S-QUAL; efficiency, system availability, fulfillment, and privacy) were used to measure the service quality of shopping websites. Subsequently, the simultaneous importance-performance analysis (SIPA) method and analytical Kano model were integrated to analyze the market competition strategies adopted among members of the shopping website industry. Finally, suggestions are provided regarding potential management methods for the case companies.
