Degradable‑Modified PE Plastic

Degradation modification of PE plastics is generally achieved via two approaches. The first is to add photo‑ and thermo‑oxidative degradation catalysts into conventional PE. After end‑of‑life, the material is oxidatively cleaved into microbially‑metabolizable low‑molecular‑weight fragments, which are finally converted into water and carbon dioxide. The second is molecular‑level redesign: cleavable ester bonds or cyclic structures are introduced into PE main‑chains through copolymerization, producing intrinsically degradable new materials with mechanical performances comparable to ordinary PE. Its most prominent features are controllable degradation behavior and retention of bulk‑material properties. Technical adjustment guarantees stable performances during service life, and degradation triggered by light, heat‑oxygen or mechanical force after discard. Meanwhile, PE can be depolymerized into high‑value monomers or oligomers via chemical recycling to realize closed‑loop circulation.

Main Applications of Degradable‑Modified PE

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

High‑Performance Multifunctional Materials: The “Lego‑style” strategy proposed by Academician Wang Yuzhong’s research team at Sichuan University degrades PE into oligomers with reactive end‑groups. Dynamic‑bond reconstruction is performed with functional modules such as flame‑retardant, antistatic and UV‑shielding moieties. New‑type materials are obtained with tensile strength nearly quadrupled, limiting oxygen index reaching 27 % for flame retardancy, together with antistatic performance, full‑band UV‑shielding and cationic‑dye dyeability, applied in electronics, textiles and special‑protection sectors.

Chemically‑Recyclable Cross‑Linked Polyethylene: Research group led by Professor Chen Changle at University of Science and Technology of China introduces cyclobutene‑fused cyclic‑ester units into PE backbone, preparing cross‑linked polyethylene (XLPE) with mechanical performances equivalent to commercial grades and mechanically‑triggered depolymerization‑recycling capability. It applies to cables, pipelines and engineering components requiring high durability and recyclability.

Compatibilizers & Functional Chemicals: Controlled oxidation or laser‑induced pyrolysis converts waste‑PE into polar‑group‑containing oligomers or long‑chain α,ω‑dienes. These products serve as compatibilizers for PLA/PE blending systems (boosting elongation at break by 70 %), or further synthesized into hydrophilic anti‑fouling membrane materials for water‑treatment and high‑performance membrane‑separation industries.
