Concerns on the environment, health and safety issues posed by synthetic resins has amplified numerous efforts of producing resin from various renewable sources. The use of plant oil as potential source of resin has attracted interest from various researchers. Jatropha Oil is a competitive source to petroleum counterparts due to its availability, biodegradability, low eco-toxicity but exhibit poor mechanical properties among many. The objective of this study is to study the effect of adding nanoparticles as reinforcing fillers to bio-based resin from Epoxidized crude Jatropha Oil (ECJO) to improve its mechanical performance. Various loadings of 0% to 4% of Al2O3 nanoparticles was tested on epoxy bio-resin. Later the specimens fabricated were cured and characterized for its mechanical properties. Addition of 1 wt% of Al2O3 nanoparticles improved the tensile strength of a bio-based epoxy resin to tensile stress of 29.37±2.00 MPa, elastic with an elastic modulus of 840.80±124.53 MPa. Further characterization at optimum addition of nano-Al2O3 resulted a glass transition temperature of 37.95˚C. In overall, the inclusion of nano-Al2O3 has definitely improved the mechanical properties of the material which will be useful for further application material engineering.

Graphical Abstract


  • The production of green and renewable bioresin from jatropha oil decorated with Aluminium oxide nanoparticles
  • Epoxidized crude jatropha oil (ECJO) and nano-Al2O3 particles are being used to optimize the property of a cured ECJO based resin consisting of 25% ECJO and 75% synthetic polymer.
  • A range of 0% to 4% of nanoparticles was tested on epoxy bio-resin. Specimens fabricated were characterized for its mechanical properties.
  • Addition of nano-Al2O3 improved tensile strength of a ECJO resin with its optimum at 1 wt% addition reaching a tensile stress of 29.37±2.00 MPa and elastic modulus of 840.80±124.53 MPa.
