采用熔融共混法制备了热塑性木薯淀粉(TPS)/二氧化硅(SiO_2)复合材料,研究了不同粒径(20 nm、200 nm和23µm)的SiO_2对热塑性木薯淀粉/SiO_2复合材料结构、形态和性能的影响。含200 nm二氧化硅的TPS/二氧化硅复合材料的塑化时间和扭矩最小,拉伸和冲击强度最高。23µm的二氧化硅颗粒对淀粉的回生促进作用最强,而200 nm的二氧化硅颗粒对淀粉的回生有抑制作用。含200 nm二氧化硅的TPS/二氧化硅复合材料具有最高的热稳定性、抗吸水性和透光性。200 nm的二氧化硅颗粒在淀粉基质中分散均匀、细小,而20 nm的二氧化硅颗粒易在TPS中聚集。在含有200 nm SiO_2的TPS/SiO_2复合材料中,球晶尺寸均匀。TPS/SiO_2复合材料为A+V混合型晶体结构,其中含23µm SiO_2的TPS/SiO_2复合材料的晶体尺寸最大。
Thermoplastic cassava starch (TPS)/silica (SiO2) composites were prepared through melt-mixing, and the effect of different SiO2particle size (20 nm, 200 nm, and 23 µm) on the structure, morphology, and properties of TPS/SiO2composites was investigated. TPS/SiO2composite containing 200 nm SiO2has the lowest plasticizing time and torque, and the highest tensile and impact strength. The 23 µm SiO2particle has the strongest effect on promoting retrogradation of starch, while the 200 nm SiO2particle could inhibit the retrogradation of starch. TPS/SiO2composite containing 200 nm SiO2has the highest thermal stability, resistant water absorption, and light transmittance. The 200 nm SiO2particle could be uniformly and finely dispersed in the starch matrix, however 20 nm SiO2particle easily aggregated in TPS. The spherulites size was uniform in TPS/SiO2composite containing 200 nm SiO2. TPS/SiO2composite indicates the mixture of A + V types of crystalline structure, and TPS/SiO2composite containing 23 µm SiO2had the largest crystal size.
