In the current study, nerve guide conduits based on a 3D graphene were synthesized by induction heating chemical vapor deposition (ICVD). Graphene was synthesized on Ni foam template at 1080 Cͦ. Fabricated samples were characterized by Raman analysis and Scanning Electron Microscopy. Raman analysis showed that the synthesized graphene is in the form of a turbostratic multilayered graphene with little defects. Cyclododecane (CD) as a temporary protective layer was used to remove nickel. After removing nickel, the free-standing 3Dgraphene structure was coated with a polymer (PCL) by drop and dip coating methods to obtain the composite conduit. A comparison of the electromechanical results of the 3D-graphene/PCL conduit and PCL conduit indicated that firstly, grapheme increased the electrical conductivity of the composite conduit which will help promote nerve regeneration and axon growth. Secondly, tensile strength and flexibility of the 3D-graphene/PCL conduit was improved compared to the PCL conduit. .","PeriodicalId":30992,"journal":{"name":"Journal of Advanced Materials in Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70773644","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 microstructural and protective properties of PEO coatings were studied by SEM, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The results showed that the coating formed at frequency of 3000 Hz had smaller pore size and better protection properties. EIS test in 3.5 Wt.% NaCl solution was also used to investigate the protective behavior of the two-layered coatings. The results showed that PEO process had a favorable effect on the protective behavior of the polymer layers.

For this purpose, HfO 2 , H 3 BO 3 , carbon active or phenolic resin were used as raw materials for carbothermal reaction. After 2-4 hours of milling the raw materials by a planetary ball in an ethanol media, the mixture was heat dried and pressed in to disks under pressure of 20-30 bar. The disks were then placed in a graphite crucible and heat-treated at 1500–1600 °C for 1 hour under flowing Ar atmosphere. The powder product was analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and backscattered electron (BSE) imaging. The heat treatment temperature, amount of boric acid, milling and heat treatment time were recognized as four factors influencing synthesis and size of HfB 2 powder particles. SEM images reported irregular morphologies with a particle size of about 2-4 µm for HfB2 powder. The best sample was obtained at a molar ratio of HfO 2 : phenolic resin carbon: boric acid = 1:5:5 at 1600 °C after 1 hour of heat treatment. XRD results confirmed synthesis of pure HfB 2 with a crystallite size of about 60 nm.","PeriodicalId":30992,"journal":{"name":"Journal of Advanced Materials in Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46413376","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}
