Single-walled carbon nanotubes and their composites with polyaniline. Structure, catalytic and capacitive properties as applied to fuel cells and supercapacitors

Abstract

The structure and hydrophilic–hydrophobic properties of SWCNTs before and after oxidative functionalization were studied by standard porosimetry method. The correlation between the values of specific surface of hydrophilic and hydrophobic pores for the two types of SWCNTs is discussed. The capacity properties of SWCNTs and their composites with polyaniline were also investigated. The composite layer is shown to have exceptionally high capacitance that is due to the large surface area of the former, as well as to the proceeding of the reversible faradaic reaction of counter ions intercalation into PANI. The structure and electrocatalytic properties of platinum metals incorporated by various methods into support of SWCNTs and their composites with PANI were studied. Kinetics of the reactions proceeding in DMFC and the mechanism of catalytic influence of the support are discussed. The structure of the catalytic layer is shown to be the main factor that determines the overall catalytic activity.

نانولوله های کربنی تک جداره و ترکیبات آنها با پلی آنیلین. خواص ساختاری کاتالیستی و خازنی به کار گرفته شده در سلول های سوختی و ابر خازنها

چکیده
خواص ساختاری و خواص آب دوست-آب گریز نانولوله های کربنی تک جداره قبل و بعد از عاملدار کردن اکسیداتیو به روش تخلخل سنجی استاندارد مورد بررسی قرار گرفتند. همبستگی بین مقادیر سطح ویژه منافذ آب دوست و آب گریز برای دو نوع از نانولوله های کربنی تک جداره مورد بحث قرار می­گیرد. خواص خازنی از نانولوله های کربنی تک جداره و ترکیبات آنها با پلی آنیلین نیز بررسی شد. نشان داده شده است که لایه ترکیبی دارای ظرفیت خازنی فوق العاده بالایی ناشی از سطح بزرگ تشکیل دهنده، و همچنین پیشرفت واکنش فارادی برگشت پذیر جاسازی یونهای شمارشگر در پلی آنیلین است. خواص ساختاری و الکترو کاتالیستی فلزات پلاتین ادغام شده با روش های مختلف برای پشتیبانی از نانولوله های کربنی تک جداره و مواد مرکب آنها با پلی آنیلین مورد مطالعه قرار گرفتند. سینتیک پیشرفت واکنشها در DMFC و مکانیسم اثر کاتالیزوری این پشتیبانی بحث می­شوند. نشان داده می­شود که ساختار لایه کاتالیستی عامل اصلی است که فعالیت کاتالیزوری کل را تعیین می­کند.

Abstract
Drainoni M-L, Houlihan B, Williams S, Vedrani M, Esch D, Lee-Hood E, Weiner C. Patterns of Internet use by persons with spinal cord injuries and relationship to health-related quality of life. Arch Phys Med Rehabil 2004;85:1872–9.
Objectives
To examine patterns of computer and Internet use among persons with spinal cord injuries (SCI) and to assess the relationship between Internet use and health-related quality of life (HRQOL).
Design
Cross-sectional survey design.
Setting
National Model Spinal Cord Injury Systems.
Participants
People with SCI enrolled in a national database.
Interventions
Not applicable.
Main outcome measures
Patterns of Internet use and relationship to HRQOL indicators: self-perceived health status, health status compared with 1 year ago, severity of depression, social integration score, occupation score, contacts with friends, business contacts, and satisfaction with life.
Results
Most subjects owned computers, had Internet access, and used the Internet regularly—primarily for email, disability and health information, and shopping. Bivariate analysis revealed significant differences in Internet access based on sociodemographics, particularly among subjects with less education and among African Americans and Hispanics. In initial univariate analysis, most HRQOL indicators were significantly better for Internet users; once sociodemographic factors were included, 4 indicators remained significant.
Conclusions
Complex factors contribute to Internet access among people with SCI, with more barriers among specific subgroups. A significant HRQOL benefit from Internet use is suggested. Targeted interventions and studies of usage patterns are recommended.
