Dispersion and functionalization of carbon nanotubes for polymer-based nanocomposites: a review

Abstract: Carbon nanotubes (CNTs) hold the promise of delivering exceptional mechanical properties and multi-functional characteristics. Ever-increasing interest in applying CNTs in many different fields has led to continued efforts to develop dispersion and functionalization techniques. To employ CNTs as effective reinforcement in polymer nanocomposites, proper dispersion and appropriate interfacial adhesion between the CNTs and polymer matrix have to be guaranteed. This paper reviews the current understanding of CNTs and CNT/polymer nanocomposites with two particular topics: (i) the principles and techniques for CNT dispersion and functionalization and (ii) the effects of CNT dispersion and functionalization on the properties of CNT/polymer nanocomposites. The fabrication techniques and potential applications of CNT/polymer nanocomposites are also highlighted.

Aggregation and morphology control enables multiple cases of high-efficiency polymer solar cells.

Abstract: Although the field of polymer solar cell has seen much progress in device performance in the past few years, several limitations are holding back its further development For instance, current high-efficiency (>90%) cells are restricted to material combinations that are based on limited donor polymers and only one specific fullerene acceptor Here we report the achievement of high-performance (efficiencies up to 108%, fill factors up to 77%) thick-film polymer solar cells for multiple polymer:fullerene combinations via the formation of a near-ideal polymer:fullerene morphology that contains highly crystalline yet reasonably small polymer domains This morphology is controlled by the temperature-dependent aggregation behaviour of the donor polymers and is insensitive to the choice of fullerenes The uncovered aggregation and design rules yield three high-efficiency (>10%) donor polymers and will allow further synthetic advances and matching of both the polymer and fullerene materials, potentially leading to significantly improved performance and increased design flexibility

The effects of leader and follower emotional intelligence on performance and attitude: An exploratory study

Abstract: Recently, increasing numbers of scholars have argued that emotional intelligence (EI) is a core variable that affects the performance of leaders. In this study, we develop a psychometrically sound and practically short EI measure that can be used in leadership and management studies. We also provide exploratory evidence for the effects of the EI of both leaders and followers on job outcomes. Applying Gross' emotion regulation model, we argue that the EI of leaders and followers should have positive effects on job performance and attitudes. We also propose that the emotional labor of the job moderates the EI–job outcome relationship. Our results show that the EI of followers affects job performance and job satisfaction, while the EI of leaders affects their satisfaction and extra-role behavior. For followers, the proposed interaction effects between EI and emotional labor on job performance, organizational commitment, and turnover intention are also supported.
