Effect of different particle size of silica on structure, morphology, and properties of thermoplastic cassava starch

Abstract
Thermoplastic cassava starch (TPS)/silica (SiO 2 ) composites were prepared through melt-mixing, and the effect of different SiO 2 particle size (20 nm, 200 nm, and 23 µm) on the structure, morphology, and properties of TPS/SiO 2 composites was investigated. TPS/SiO 2 composite containing 200 nm SiO 2 has the lowest plasticizing time and torque, and the highest tensile and impact strength. The 23 µm SiO 2 particle has the strongest effect on promoting retrogradation of starch, while the 200 nm SiO 2 particle could inhibit the retrogradation of starch. TPS/SiO 2 composite containing 200 nm SiO 2 has the highest thermal stability, resistant water absorption, and light transmittance. The 200 nm SiO 2 particle could be uniformly and finely dispersed in the starch matrix, however 20 nm SiO 2 particle easily aggregated in TPS. The spherulites size was uniform in TPS/SiO 2 composite containing 200 nm SiO 2 . TPS/SiO 2 composite indicates the mixture of A + V types of crystalline structure, and TPS/SiO 2 composite containing 23 µm SiO 2 had the largest crystal size.
