“…Among them, oxidized starch (OST) often exhibits excellent physicochemical properties including low viscosity, high stability, and excellent film-forming and binding properties which are markedly different from those of starch . To date, OST has been widely applied in fields such as food, paper coatings, , biomaterials, thermoplastic starch, and so on. ,, However, there are few reports of its new application in flame retardance of polymers.…”

Novel c-6 position oxidized corn starch (OST) with high carboxyl content (26.3–54.5%) was prepared by a green method, using hydrogen peroxide as the oxidant. The as-obtained OSTs were then used as flame-retardant carbon sources with microencapsulated ammonium polyphosphate (MFAPP) in epoxy resin (EP). Compared to EP, the obtained EP/MFAPP/OST composites exhibit significantly enhanced flame retardancy. The introduction of only 6.25 wt % OSTs and 6.25 wt % MFAPP results in remarkably increased limiting oxygen index and decreased heat release rate, and all composites can reach UL94 V-0 rating. Thermogravimetric analyses and cone calorimetry results suggest both OSTs and MFAPP have good catalytic charring effects, and the increased carboxyl content benefits the char formation of the composites. Because of the formation of compact char on the sample surface during combustion, the transfer of oxygen, heat, and flammable gas products is inhibited; the flame retardancy of EP/MFAPP/OST composites is thus remarkably enhanced.

A novel method of starch modification was developed to obtain thermoplastic starch plastics with improved comprehensive properties. Corn starch was oxidized under mild conditions using sodium periodate to prepare dialdehyde starch, which had an acceptable average molecular weight. The dialdehyde starch with 35.2% carbonyl content was reacted with different alcohols (methanol, ethanol, and glycol) to prepare a series of novel starch derivatives, whose structures were characterized by 1H‐NMR and FT‐IR. The thermogravimetric analysis showed that these starch derivatives had an improved thermal stability compared with dialdehyde starch. Thermoplastic starch and its derivatives were prepared when water and glycerol were added as plasticizers. The modified thermoplastic starch and its derivatives had better mechanical properties than other modified starches, and lower humidity absorption than conventional thermoplastic starches. The highest tensile strength and elongation at break reached 17.5 MPa and 149%, respectively, and the highest humidity absorption was about 37%.
