dc.description.abstractThis experimental study is conducted to investigate the effects of boric acid additive into polypropylene in terms of microstructure formation and thermal properties. Boric acid granules are added into pure polypropylene at three mass rates of 0.5, 1.5, and 2.5% which are notated as PP/BA-0.5, PP/BA-1.5, and PP/BA-2.5, respectively. The pure polypropylene material (pure PP) and boric acid reinforced polypropylene composite materials (PP/BA) are manufactured in an injection molding machine. The microstructure of composite materials is examined with an SEM (scanning electron microscope) device. Thermal analyses are conducted by using a TGA (thermogravimetric analyzer) device. In addition, thermal conductivities of composite materials are measured between 10 and 50 degrees C temperatures. SEM images show that boric acid at 0.5% additive rate forms a homogeneous composite by uniformly spreading the polymer chains, while boric acid at high additive rates of 1.5% and 2.5% becomes agglomerated within the polymer. TGA analyses show that the initial evaluation degradation temperature (T-i) tends to decrease with the addition of boric acid. Thermal conductivity for all examined materials almost linearly increases with temperature at a slope of about 0.0004 [(W m(-1) K-1)/K]. Thermal conductivity is reversely proportional to the boric acid additive rate. The thermal conductivity for 2.5% boric acid added polypropylene is about 5% less than pure polypropylene.
