Abstract

A novel nanocomposite having graphene sheets is described. The nanocomposite may be used for medical devices such as bone cement, dentures, paper, paint and automotive industries. A novel Microwave irradiation (MWI) was used to obtain R-(GO-(STY-co-MMA)). The results indicate that the nanocomposite obtained using the MWI had a better morphology and dispersion with enhanced thermal stability compared with the nanocomposite prepared without MWI. An average increase of 136% in hardness and 76% in elastic modulus were achieved through the addition of only 2.0 wt % of RGO nanocomposite obtained via the MWI method.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A nanocomposite composition, comprising:
 a styrene added using a specific weight ratio;   a methyl methacrylate equal to the ratio of the specific ratio of the styrene; and   a graphene powder added using a weight/weight % of the styrene and methyl methacrylate ratio.   
     
     
         2 . The composition of  claim 1 , wherein the specific weight ratio for the styrene is 1. 
     
     
         3 . The composition of  claim 1 , wherein the specific weight ratio of the methyl methacrylate is 1. 
     
     
         4 . The composition of  claim 1 , wherein the weight/weight % for the graphene powder is 2. 
     
     
         5 . A nanocomposite composition, comprising:
 a graphene powder added using a weight/weight % of a styrene and methyl methacrylate ratio to be used for a specific article.   
     
     
         6 . The nanocomposite of  claim 5 , further comprising:
 the styrene added using a specific weight ratio, wherein the specific weight ratio for the styrene is 1; and   the methyl methacrylate equal to the ratio of the specific ratio of the styrene.   
     
     
         7 . The composition of  claim 6 , wherein the specific weight ratio of the methyl methacrylate is 1. 
     
     
         8 . The composition of  claim 5 , wherein the weight/weight % for the graphene powder is 2. 
     
     
         9 . The composition of  claim 5 , wherein the specific article is at least one of a bone cement, denture, paper, paint and automotive industry article.
