Case Study

Elastic Coating Of Exfoliated Graphite Nanosheets Of Poly(Butadiene-Co-Acrylonitrile), Amine Terminated

Cho, Donghwan, and Jeong Hyeon Hwang. Advances in polymer technology 32.4 (2013).

In this study, exfoliated graphite nanosheets (EGN) were prepared from graphite intercalation compounds by microwave and ultrasonic processes and coated with liquid rubber Poly(butadiene-co-acrylonitrile), amine terminated (ATBN) at room temperature. Different concentrations were formed by ultrasonic and deep freezing methods. The presence of ATBN coating on EGN particles was characterized by using multiple analytical tools such as X-ray photoelectron spectroscopy, energy dispersive X-ray spectroscopy, elemental analysis, X-ray diffractometer, thermogravimetric analyzer, and scanning electron microscopy. It was clearly demonstrated that the ATBN coating level of EGN particles strongly depends on the coating concentration. The characterization results are consistent with each other, indicating that the elastic coating of EGN with ATBN was successfully carried out. The incorporation of 1 wt% EGN with 10 wt% ATBN into epoxy resin increased the toughness of the epoxy by 18%. It was proved that the EGN elastomer coating containing ATBN can effectively toughen epoxy resin with only a very small amount of 0.1 wt% ATBN compared with epoxy resin.
ATBN with different ATBN concentrations (0, 3, 5 and 10 wt%) was uniformly coated on the EGN surface by deep coating and deep freezing. The coating process is shown in Figure 3. According to the given concentration, ATBN was mixed with 50 mL of chloroform in a 300 mL beaker. ATBN was fully dissolved in chloroform at 40 kHz for 3 min at ambient temperature using an ultrasonic bath, and then EGN particles were poured into the solution. By continuous ultrasonic treatment, EGN particles were uniformly dispersed in the solution. The EGN particles obtained after filtration were dried in a vacuum oven at 45 °C for 12 h and then mixed with distilled water under 40 kHz ultrasonic conditions for 30 min. After freeze drying at -70 °C for 72 h using a freeze dryer, EGN particles coated with ATBN were finely produced.
