Abstract

Carbon allotropes such as graphene and multiwalled carbon nanotube (MWCNT) are studied for an extensive range of applications. Various exfoliation techniques were employed to yield the best form of generated allotropes. Liquid phase exfoliation utilizes the technique of sonication of these allotropes in the solvent, results in the best desired form of the high quality, safe, simple and economically viable final product. This study discusses liquid-phase exfoliation of graphene and MWCNT in chloroform. Their absorbance intensity has shown a contrast solubility profile with respect to different weight percentages of each allotrope. The comparative study was further analyzed with modification of bioglass (BG) within the suspensions, of which hazards in agglomerations of allotropes’ particles as concentration increases could potentially give a prevention insight for better preparation and processing materials formulation. Hence the study aims in reporting UV absorbance intensity of various weight percentages of liquid exfoliated graphene and MWCNT particles, with the addition of BG in chloroform due to their unique structures and remarkable properties and their exploitation in diverse potential applications, including the biomedical engineering field especially in the field of bone tissue engineering.
