Abstract
Abstract The objective of this work is to develop graphene oxide (GO) incorporated butyl rubber (IIR) nanocomposites by three different methods: direct addition approach (DAAM), single step method (SSM) and two step method (TSM). Chlorobutyl rubber was used as a compatibilizer in SSM and TSM. Mechanical properties of developed nanocomposites was increased and gas permeability co-efficient was decreased up on addition of GO content in IIR matrix. Maximum technical properties was achieved for the nanocomposite with 1.6 wt.% of GO in all methods was achieved due to better interfacial bonding with IIR matrix. When GO content increases above 1.6 wt.% in IIR matrix leads to agglomeration which resulted in deterioration of mechanical properties. HR-TEM studies revealed that nanocomposites prepared by TSM shows exfoliated structure of GO in IIR matrix due to homogenous distribution when compared to the nanocomposites prepared with DAAM and SSM.
Highlights
Nanocomposites are currently used in several fields IIR nanocomposites by reinforcing graphene oxide (GO) in presence and and new applications are being continuously developed like absence of compatibilizer using DAAM, single step method (SSM) and two step method (TSM)[16].innerwalls of tires, thin film capacitors for computer chips, Mechanical and gas permeability properties of the preparedO-rings, ball bladders, fiber optic compounds, hand gloves, nanocomposites were evaluated and the properties of the impellers blades and food packaging, etc[1]
Nanocomposites containing IIR with GO content of 1.6 wt.% (D4, S4 and T4) exhibited higher tensile strength (TS), tear strength (TES) and modulus at 100 and 300% when compared to pure IIR in all three preparation methods (DAAM, SSM and TSM)
Graphene oxide nanocomposites was successfully developed in presence and absence of compatibilizer using three different methods (DAAM, SSM and TSM)

Nanocomposites are currently used in several fields IIR nanocomposites by reinforcing GO in presence and and new applications are being continuously developed like absence of compatibilizer using DAAM, SSM and TSM[16]. CIIR was used as a compatibilizer in this work matrix to increase the macroscopic properties. Of nanoscale, distribution of filler or measured nanostructures in the base matrix with high surface to volume ratio can enhance the physico-mechanical properties and unique 2. Rubber nanocomposites is one of the composites which were developed by several researchers around the world using different rubbers such as natural rubbe r(NR)[2,3,4], butadiene rubber (BR), butyl rubber (IIR)[5], chlorobutyl rubber (CIIR)[6,7], epoxidizednatural rubber (ENR)[8], styrene butadiene rubber (SBR), styrene butadiene styrene rubber (SBS) and nitrile butadiene rubber (NBR) for various applications.
