Graphene (AIGO) has few layers of carbon arranged in hexagonal rings with oxygen
atoms.
AIGO is a most attractive filler for making composite materials like particle/fiber boards
due to its ease of addition, environmental friendliness, low cost, safety, excellent
bonding etc.
Addition of AIGO graphene substantially enhances physical & mechanical properties
of MDF panels.
AIGO is added to the urea-formaldehyde resin at levels of 2 to 6% & then mixed with
wood or other fibers followed by the usual manufacturing process of MDF boards.
Thickness swelling: is decreased by about 45% due to the blockade of pores of the wood fibers as well as allows better curing of the Urea-formaldehyde resin.
Water absorption: is improved by about 20%. By adding AIGO, the pores get covered & produce a superficial layer which reduces the water absorption by the MDF panels.
Thermal conductivity: improved by up to 40%. AIGO augments heat transfer throughout the hot processing of MDF.
Tensile Strength: increased by about 28%.
Modulus of Elasticity (MOE): increased by about 19%. Due to the high thermal
conductivity, early & fast curing of the Urea-formaldehyde resin occurs & thus only optimum quantity of AIGO must be used (to get better MOE).
Modulus of Rupture (MOR): increased by about 38%. Enhanced MOR of the MDF panels is due to better curing of the resin during pressing & better density of the urea-formaldehyde resin.
