Abstract

Introduction

Procedures such as ligament reconstruction, tendon reinsertion and osteosynthesis are common in knee surgery, sports medicine and orthopedic surgery. In these possible surgical procedures, suture anchors, interference screws, synthesis materials and even prostheses if necessary are used. Materials that have a durability and biological interaction - absorbable or not -, therefore, increased durability, as well as improved biocompatibility, which includes suppression or even a possible bactericidal specificity, are properties of interest in implants . Thus, the carbonaceous, in this work the graphene and the carbon nanotubes emerge as the protagonists of carbon allotropes. The differential of this study is the synthesis and characterization of these carbonaceous not only in orthopedic materials, but also in the application in the surgical area.

Objective

to synthesize and characterize carbonaceous, mainly graphene and derivatives for biological and medical application studies. In this study we present the synthesis and characterization of carbonaceous with possible application in not only medical but also biological areas.

Methods

Graphene and the carbon nanotubes studied in this work were deposited by atmospheric pressure vapor-phase chemical deposition (APCVD) and plasma-assisted vapor-phase chemical deposition (PECVD) techniques. Raman microscopy is a technique that provided chemical and structural information on different materials.

Results

In the case of carbonaceous materials, this technique made it possible to identify the presence of carbon and the type of hybridization (sp, sp2, sp3), and thus the allotropic form of carbon in the material were characterized. Specifically, graphene and carbon nanotubes were configured by hexagonal lattices with strong covalent sp2. Thus, the characteristics of graphene's Raman spectrum were related to the presence of the D band, which appears at approximately 1350 cm-1 , the G band around 1582 cm-1 , and the 2D band around 2700 cm-1. Scanning electron microscopy contributed to the identification of both carbonaceous deposits and the total coverage of the cylinder.

Conclusion

The proposed method using the APCVD technique for the production of carbonaceous material and subsequent characterization using Raman Spectroscopy and Scanning Electron Microscopy showed satisfactory results for the possible application of carbonaceous material.
