ABSTRACT Inspired by the mortise and tenon structure in ancient Chinese architecture, polymer composites with interfacial interlocking structures were developed utilizing “reverse compatibility” between polymers inorganic fillers, porous materials obtained for wastewater purification after degradation of composites. In detail, PBATT or HDPEF prepared poly (butylene adipate‐co‐terephthalate) (PBAT) high‐density polyethylene (HDPE) blended montmorillonite (MTT) Mica flour (MF) possessing opposite compatibility. Afterward, mass ratios 1/9 2/8 re‐blended to obtain PBATT/HDPEF a “zipper” “mortise tenon” interface structure. Firstly, compared PBAT/HDPE‐2/8 composites, PBATT/HDPEF‐2/8 exhibited excellent mechanical properties, including tensile strength enhanced 25% tear improved 14.1%. Moreover, formed fillers advanced hydrophilicity, water permeability, properties Remarkably, smaller contact angle (WAC) (65.9°), more considerable WAC difference within same period (6.1°), significant weight loss (4.5%) displayed than other samples. More interestingly, preparation cycle was shortened at conducive adsorption heavy metal ions.

This study explores the valorisation of alum sludge, a byproduct water treatment processes, as sustainable reinforcement material in Poly(butylene adipate-co-terephthalate) (PBAT) composites. The research aims to address industrial waste challenges by developing eco-friendly composite materials while promoting circular economy principles. Alum sludge particles, classified into two size distributions (<63 µm and <250 µm), were incorporated PBAT matrices at varying concentrations. composites characterised for their mechanical, thermal, crystallographic, moisture adsorption properties; biodegradation behaviour was evaluated through soil burial tests over 60 days. results revealed that 63 particle fraction exhibited superior performance compared 250 fraction, demonstrating improved mechanical properties, reduced degradation rates, enhanced interfacial bonding. Composites with 5 wt.% achieved balance between processability, outperforming other filler concentrations examined. innovative approach highlights potential upcycling functional materials, advancing management manufacturing. Furthermore, observed variation rates suggests these can be tailored applications requiring controlled compostability.
