Abstract Ethylene/α-olefin copolymers are produced in huge scale and widely used, but their after-use disposal has caused plastic pollution problems. Their chemical inertness made re/upcycling difficult. Ideally, PE materials should be de novo to have a circular closed-loop lifecycle. However, synthesis of ethylene/α-olefin copolymers, including high-volume, linear low-density as well high-value olefin elastomers block presents particular challenge due difficulties introducing branches while...
<title>Abstract</title> During the past 70 years, it has been well established that melts of crystalline homopolymers adopt disordered random coil conformations and are densely packed in globules above melting temperature (<italic>T</italic><sub>m</sub>). Flow-induced melt orientation promotes crystal nucleation polymorphism upon cooling. Here, we present polymerization-induced nano-to-mesoscale condensed-ordering as order-to-order order-to-disorder (O-D) transformations at...
<title>Abstract</title> Polyolefins are the most commonly used synthetic materials in world. However, unmanaged postconsumer polyolefins dominate global plastic waste, and blending polypropylene (PP) polyethylene (PE) (wastes) results undesirable poor mechanical properties owing to their thermodynamic incompatibility melt. Therefore, great challenges remain for melt-compounding recycling of PP PE prepare high-performance alloys. Here, we present a series super-ductile, ultra-tough...
The in situ growth of one-dimensional magnetite (Fe3O4) nanowire (NW) arrays with deterministic and tunable control over their orientation morphology on a wide range flexible low heat resistance substrates is still challenge. Herein, facile method controlling the Fe3O4 NW polypropylene (PP) nonwoven fabric surface (PP-g-PAO/Fe3O4) through simultaneous radiation induced graft polymerization coprecipitation processes was realized. We demonstrated geometric properties coprecipitated NWs via...
High-strength and high-temperature triple shape memory elastomers from multiphase polyolefin elastomer (POE)/polypropylene (PP) blends are prepared via radiation-induced vulcanization. Irradiation generates cross-linking mainly in the amorphous sequences of POE chains, long chain branches regions PP crystals, grafting between chains at interface phases. The discoid-like phase with an average size 1.6 × 11 μm2, dispersed matrix, is aligned parallel to plane recompressed films. lamellar...
Polyethylene (PE)-based materials, including ethylene homopolymers and its random or block copolymers with α-olefins, are the most produced synthetic materials globally, but current practices in their production, use, after-use that follow linear economy framework have taken a huge toll on both environment society. 1,2 Although several notable advances been made PE chemical re/upcycling, 3-10 energy-efficient selective catalytic processes still lacking due to inherent inertness of C-C C-H...
