Personal review record, as a form of personally identifiable information, refers to the past review information of a reviewer. The disclosure of reviewers’ personal information on electronic commerce websites has been found to substantially impact consumers’ perception regarding the credibility of online reviews. However, personal review record has received little attention in prior research. The current study investigated whether the disclosure of personal review record influenced consumers’ information processing and decision making by adopting event-related potentials (ERPs) measures, as ERPs allow for a nuanced examination of the neural mechanisms that underlie cognitive processes. At the behavioral level, we found that the purchase rate was higher and that the reaction time was shorter when the review record was disclosed (vs. when it was not), indicating that the disclosed condition was more favorable to the participants. Moreover, ERPs data showed that the disclosed condition induced an attenuated N400 component and an increased LPP component relative to the undisclosed condition, suggesting that the former condition gave rise to less cognitive and emotional conflict and to more positive evaluations. Thus, by elucidating potential cognitive and neural underpinnings, this study demonstrates the positive impact of reviewers’ disclosure of personal review record on consumers’ purchase decisions.

Electromagnetic interference (EMI) shielding materials with low thickness and improved EMI shielding performance are highly required. Herein, by utilizing the plasma-enhanced chemical vapor deposition (PECVD) method with the optimized source power of the plasma generator, vertical graphene nanowalls (VGNs) with a relatively rapid growth rate of ∼5 μm•h −1 were prepared on substrates. The porous conductive VGNs exhibited preferable EMI shielding performance. In a frequency range of 8.2−12.4 GHz, the EMI shielding effectiveness (SE) value of VGNs with a thickness of 47.5 μm could reach 26.2 dB. In addition, VGNs with controllable thickness were also synthesized on Cu foam substrates. The combination of VGNs and Cu foam significantly improved the porosity and interfacial coupling effect of the composites. By growing VGNs with a thickness of ∼20 μm on the Cu foam, their absorption efficiency got largely enhanced by 13.8 dB (32.2%) compared with the pristine Cu foam. Subsequently, the total EMI SE of the VGNs/Cu foam composite films got enhanced by 13.5 dB (20.8%) compared with the pristine Cu foam. The VGNs and their composites with preferable EMI shielding performance establish potential for practical applications in EMI shielding.
