The increasingly serious environmental pollution caused by petroleum-based nondegradable plastics has evoked intense research interest in the development of sustainable and degradable bioplastics. Starch is one of the most promising biopolymers for the preparation of bioplastic. However, it is still a great challenge to develop starch bioplastics with high strength, low water sensitivity, and excellent water resistance. Herein, we reported a facile chemical modification method for the synthesis of a novel starch bioplastic. In this process, an easily available starch derivate, dialdehyde starch (DAS), is cross-linked using diamine based on dynamic imine chemistry to prepare DAS-based polyimine (DAS-PI). This DAS-PI exhibits excellent thermal malleability, and it can be easily thermoformed into novel starch bioplastic without using any plasticizer. The resulting starch bioplastic shows high mechanical strength (40.6 MPa), high thermal stability, and excellent water/chemical resistance, as well as heat-induced self-healing ability. Moreover, it can be easily chemically degraded and recycled. This work provides a novel method of producing high-performance starch bioplastics without using plasticizers.

“…Similarly, there were huge amount of efficient flame-retardant nanocomposites fabricated by dual-phase free-radical capturers successfully. [140][141][142][143][144][145][146][147][148][149] Therefore, these dual-phase hybrid free-radical capturers often possess a higher fire-retardant efficiency than the condensed-phase ones.…”

“…However, at high loading levels of IFR, the presence of PMGO does not contribute to the thermal stability of PP in air condition. Similarly, there were huge amount of efficient flame‐retardant nanocomposites fabricated by dual‐phase free‐radical capturers successfully 140–149 . Therefore, these dual‐phase hybrid free‐radical capturers often possess a higher fire‐retardant efficiency than the condensed‐phase ones.…”

Polymeric materials are ubiquitously utilized in modern society and continuously improve quality of life. Unfortunately, most of them suffer from intrinsic flammability, significantly limiting their practical applications. Fundamentally, free-radical reaction is a critical "trigger" for their thermal pyrolysis and following combustion process regardless of the anaerobic thermal pyrolysis in the condensed phase or aerobic combustion of polymers in the gaseous phase. The addition of free radical scavengers represents a promising and effective means to enhance the fire safety of polymeric materials. This review aims to offer a state-ofthe-art overview on the creation of fire-retardant polymeric nanocomposites by adding fire retardants with an ability to trap free radicals. Their specific modes of action (condensed-phase action, gaseous-phase action, and dual-phases action) and performances in some typical polymers are reviewed and discussed in detail.Following this, some key challenges associated with these free-radical capturers are discussed, and design strategies are also proposed. This review provides some insights into the modes of action of free radical capturing agents and paves the avenue for the design of advanced fire-retardant polymeric nanocomposites for expanded real-world applications in industries.

“…Furfurylamine, an aromatic amine obtained from the reductive amination of furfural can also be, mixed with PA in order to manufacture organic FR for different polymeric materials. 83 In a recent study by Ye et al, 84 biobased FR consisted of furfurylamine (FA) and PA was synthesized by using the one-step green synthesis technique to endow PLA flame retardancy. In this case, amino group from FA interacted with phosphate groups from PA.…”

The article reviews the different methods of which, phytic acid (PA) can be employed as a flame retardant (FR) filler for different polymeric materials. The methods are critically discussed, based on the available literature and patents. Depending on the method used and the addition of FRs into a PA flame retarded system, different flame retarding modes of action and fire resistance performances are attained. The mechanism of action for PA‐based system remains similar to those observed in other phosphorus‐based FRs, namely, condensed and gas‐phase mechanisms.
