“…Because of the property of sodium bicarbonate to release CO 2 gas after decomposition, it is used as the most common chemical blowing agent to produce polymeric foams [ 34 , 35 ], and it can be used as a flame retardant additive in polymers and paints [ 36 ].…”

Epoxy composites filled with 0.5 wt% of multi-walled carbon nanotubes (MWCNTs), 10 and 15 wt% of boric acid and sodium bicarbonate separately, as well as composites filled with a combination of MWCNTs-boric acid and MWCNTs-sodium bicarbonate were prepared. The thermal behavior of the prepared samples was investigated under heating in oxidative environment using thermogravimetric analysis. The hardness was measured using the Shore D hardness test. To evaluate the flammability of the samples, the ignition temperature and time-to-ignition were determined. It was concluded that sodium bicarbonate in the studied concentrations (10 and 15 wt%) is not appropriate for use as a filler capable of improving the thermooxidative stability and reducing the flammability of epoxy polymers. The improvement in the thermal properties can be achieved by using the combination of boric acid and multi-walled carbon nanotubes as fillers. The thermooxidative destruction of the samples filled with boric acid passes more slowly and more evenly via the formation of B2O3 as a result of its decomposition.

Natural fiber is gaining more interest in these days due to its low cost, less weight and density that is make the natural fiber more attractive. Present work demonstrates jute fiber is used as reinforcement material and epoxy is used as a matrix material. And cenosphere is used as filler or secondary reinforcing material which will add better properties the jute fiber/epoxy composite. Various proportions of cenosphere is added in the composite to characterize the water and chemical absorption behavior and thickness swelling behavior of the composites. Water absorption tests was carried out for three different water medium and chemical absorption test was performed for two different chemicals. The composite samples were kept for long interval of time to analyze the absorption behavior.

“…At the further heating above 800 °C Na 2 CO 3 gradually decomposes into sodium oxide and carbon dioxide. Due to the property of releasing CO 2 gas upon heating and decomposition, sodium bicarbonate is widely used in fire extinguishers as a fire-suppression agent [21,22] and can be used as well as flame retardant additive to polymers and paints [23][24][25]. Therefore, it is of interest to study sodium bicarbonate as epoxy polymer filler.…”

The epoxy composites filled with 5 and 10 mass % of sodium bicarbonate were prepared. Sodium bicarbonate at the heating decomposes into sodium carbonate, carbon dioxide and water. As a result, sodium bicarbonate is able to slow down the combustion process when it used as polymer filler. The thermal stability of the prepared samples was investigated at the heating in air using thermal analysis. The mechanical characteristics of epoxy composites were also studied. The gaseous products of thermal oxidative degradation were studied using mass spectrometric analysis. It was found that sodium bicarbonate accelerates the process of thermal oxidative degradation of the epoxy composites in the initial stage, but enhances thermal stability in the final stage. The addition of boric acid to sodium bicarbonate as filler is recommended to improve the thermal stability of the epoxy polymer.
