Unfortunately, due to inconsistent nanotube quality, weak interfacial bonding and poor dispersion, current nanotube-based composites fail to realise their anticipated potential. In this study consistent quality nanotubes have been deposited onto preformed substrates of mesh and wire using an optimised large scale catalytic chemical vapour phase deposition apparatus. The bi-directional planar system of nanotubes has then been integrated into an epoxy matrix. This study investigates the interfacial shear strength between aligned carbon nanotubes and epoxy resin. Optimisation of this interfacial region influences the mechanical behaviour of composite materials and has considerable industrial applications in the aerospace and manufacturing industries. The surface chemistry of nanotubes was modified by plasma treatment and monitored using X-ray photoelectron spectroscopy. Mechanical testing with a custom designed adhesiometer suggested a possible improvement in interfacial shear strength. Optical microscopy was used to determine the failure mechanisms between the carbon nanotube and epoxy resin.","PeriodicalId":192889,"journal":{"name":"2008 International Conference on Nanoscience and Nanotechnology","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122959984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrical and optical characteristics are significantly influenced by the thickness of the emissive layer. When the thickness of composite film is thinned to about 103 nm, the maximum luminance of 4100 cd/m2 as well as maximum luminous efficiency of 1.35 cd/A can be achieved at 9.6 V and 7.6 V, respectively. However, the electroluminescence spectra reveal that the emission contribution is dominated by the emission from DBPPV. A maximum ratio of emission intensity of QDs to that of DBPPV is about 38 %, which indicates the contribution of QDs is minor. In addition, the post- annealing effect on device performance was also investigated. In contrast to previous reports, no obvious improvement can be observed by post-annealing.","PeriodicalId":192889,"journal":{"name":"2008 International Conference on Nanoscience and Nanotechnology","volume":"1329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115651953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
