Degradation‑Modified PE Plastic

Degradation‑modified PE is realized mainly through two technical routes. The first route introduces photo‑ and thermo‑oxidative degradation catalysts into conventional PE. After end‑of‑life, the material undergoes oxidative cleavage into low‑molecular‑weight fragments metabolizable by microorganisms, and is finally converted into water and carbon dioxide. The second route adopts molecular‑level redesign: cleavable ester bonds or cyclic structures are incorporated into the PE main‑chain via copolymerization to produce intrinsically degradable new materials with mechanical properties comparable to conventional PE. Its most outstanding features are controllable degradation behavior and retained material performance. With technical adjustment, the material maintains stable properties during service life and initiates degradation triggered by light, heat‑oxygen or mechanical force after disposal. It can also be depolymerized into high‑value monomers or oligomers via chemical recycling to achieve closed‑loop circulation.

Main Applications of Degradation‑Modified PE

Agricultural & Packaging Films: This is the most mature application field for degradation‑modified PE. Photo‑thermo‑oxidative degradation catalysts are compounded to produce agricultural mulch films, shopping bags, garbage bags and packaging films. After service, these products disintegrate and biodegrade into water and carbon dioxide under natural conditions, effectively alleviating white pollution.

High‑performance Multifunctional Materials: Following the “Lego‑strategy” proposed by Academician Wang Yuzhong’s research team at Sichuan University, PE is degraded into oligomers with reactive end‑groups, which are reconstructed with functional modules of flame‑retardancy, antistatic property and UV‑resistance through dynamic bonds. The resulting new material achieves nearly 4‑fold higher tensile strength, together with flame‑retardant performance (LOI 27 %), antistatic capacity, full‑band UV‑shielding and cationic‑dye dyeability. It is applied in electronics, textiles and special‑protection fields.

Chemically‑Recyclable Cross‑linked Polyethylene: Research team led by Professor Chen Changle at University of Science and Technology of China incorporated cyclobutene‑fused cyclic ester units into PE main‑chains, obtaining cross‑linked polyethylene (XLPE) with mechanical performance equivalent to commercial grades and mechanically‑triggered depolymerization‑recyclability. It is suitable for cables, pipes and engineering components requiring high durability and recyclability.

Compatibilizers & Functional Chemicals: Through controlled oxidation or laser‑induced pyrolysis, waste PE is converted into polar‑group‑containing oligomers or long‑chain α,ω‑dienes. They can serve as compatibilizers for PLA/PE blends (improving elongation at break by 70 %), or further synthesized into hydrophilic anti‑fouling membrane materials for water‑treatment and high‑performance membrane‑separation industries.
