There is a great deal of interest in the study of the morphology of cured epoxy resin. Generally the surfaces of the cured samples or fracture surfaces, unetched or suitably etched, are examined on the transmission electron microscope using the two-stage replica method. The replicating fluid commonly used is 25% polyacrylic acid (MW ∼ 250,000) solution in water. It dries to a brittle replica which is removed by mechanical prying with the help of tweezers; extreme caution is required to ensure that it is not damaged. It has been shown that for fractographic studies of epoxy resin, replication based on PAA can give rise to artifacts and hence it is necessary to back it uo with other evidence, e.g. from the SEM. The standard replicating fluid, containing 10% cellulose acetate in acetone, gives a softer and easily removable replica but the acetone can affect the surface of epoxy resin. To circumvent the latter problem, a modified replication method was developed and is described here.
