Objective
Polymeric material products are ubiquitous in various fields in day-to-day life, while a key limitation is most of polymeric materials are flammable. Aim to improve the fire retardancy of polymeric materials, circumvent the drawback of traditional fire retardants (FRs), create novel functionality, in this project, new generation sustainable environment-friendly multifunctional FR and high performance polymer nanocomposites are developed via combination of innovative molecular design, sophisticated chemical synthesis and advanced processing. Layered double hydroxide (LDH), low-cost sustainable environment-friendly nanofiller with good fire retardance, is chosen as the main candidate for offering the fire retardant framework. The multifunctional biobased modifier, β-cyclodextrin(CD)-based (char agent), with high fire retardance, excellent anti-UV property (via combined with chalcone extracted from plant) functional group and strong ionic-exchange capability are designed, synthesized, characterized and used to modify LDH in order to develop multifunctional LDH with excellent fire retardance and anti-UV property. Phytic acid sodium salt derived from plants will be used as co-modifier for LDH in order to provide biobased phosphorus storage (acid source). This combination will form nanoscale biobased intumescent fire retardants in the interlayer of LDH, leading to the fire retardant efficiency is improved significantly compared with traditional organic surfactant (being flammable) modified LDH. To evaluate fire retardant efficiency, anti-UV property and other properties, two typical polymers, epoxy resin and PP, are chosen as polymer models. As novel sustainable multifunctional nanoscale fire retardant, it integrates the present advantages from inorganic-FR, intumescent-FR, nano-FR and reactive-FR in the state-of-the-art and possesses new properties, owning the feathers of sustainability, environmental friendliness, high efficiency, smoke suppression and multifunction.
