Although the large-scale graphene oxide material production via bulky routes, graphene oxide (GO)still represents less than half of the global market. The primary reason behind this trend is the limitation of reconducting a homogeneous thin-film from scattered nanosheets that are generated with robust methods to match the industrial facilities. In this paper, a large -scale graphene oxide (GO) layers were synthesized by a simple facile technique through merging approach between the layerby- layer assembled (LBL) and spin coating (S) techniques. The growth conditions were also correlated with optical performance for three different GO accumulations, which the thin-film with 8 layer (GO8) showed adequate optical performance corresponding toa successful building layer fromGO flakes with minor defects. The crystalline, electronic, and morphologystructure of prepared GO films are confirmed via XRD, FTIR, Raman spectroscopy, SEM and AFM respectively. Finally, these as-produced GO thin-films can increase the utility of GO usage in several applications.
