    Recently, the research team of polymer foam materials of Beijing Technology and Business University used two-phase blending, nanocomposite, expansion of links and other technical strategies to modify polymers such as polylactic acid, polybutylene succinate, polyadipic acid-butylene terephthalate, etc.
    , and achieved a series of research results
    in biodegradable polymer foaming molding methods, cell structure regulation, foam performance optimization, etc.

    The research team prepared branched polybutylene succinate/cellulose nanocrystalline nanocomposite foam
    by supercriticalCO2 foaming.
    Due to the formation of branched structure and the addition of biomass filler, the initial crystallization temperature of polybutylene succinate composite material increased by 11.
    8 °C, the energy storage modulus increased by 2 orders of magnitude, and the foaming rate of composite foam material could reach 37.

    .
    This research provides a feasible development strategy
    for the development of energy-saving and environmentally friendly highly insulating polymer foam materials.

    The team also used supercriticalCO2 foaming to prepare ultra-high foaming rate polylactic acid/carbon nanotube nanocomposite foam
    .
    Rheological performance tests have shown that the energy storage modulus of this nanocomposite is 3 orders of magnitude
    higher than that of pure polylactic acid.
    The foaming rate of the nanocomposite foam can reach up to 49.
    6 times, which provides a new idea
    for the development of other thermoplastic polyester foam materials with ultra-high foaming rate.
