Growth abnormality is common in children with cerebral palsy. Malnutrition and overnutrition both exist in children with cerebral palsy. Characteristics at different age stages and motor functional levels should be taken into consideration in the management of growth and nutrition in this population.

The interface is a critical issue for metal–organic‐framework hybrid membranes in propylene separation. Here, a covalent‐linking strategy is reported for strikingly reinforcing the interfacial compatibility in a ZIF‐8‐based membrane. A functionalized ZIF‐8 material named ZIF‐8‐CN is synthesized using the mixed‐ligand approach. ZIF‐8‐CN has an identical crystalline structure to ZIF‐8, and the 4,5‐dicyanoimidazole ligand is available for further functionalization. Covalent linkage of ZIF‐8‐CN with PIM‐1 is driven by the thermal reaction of the cyano groups on both entities, which strengthens the filler–polymer connection in the ZIF‐8‐CN@tPIM‐1 membrane. ZIF‐8‐CN@tPIM‐1 exhibits remarkably enhanced propylene permeation property with C3H6/C3H8 selectivity of ≈28, which is 350% and 180% higher than those on non‐treated ZIF‐8‐CN/PIM‐1 and non‐functionalized ZIF‐8@tPIM‐1, respectively. Additionally, ZIF‐8‐CN@tPIM‐1 shows the highest C3H6 permeability of ≈370 Barrer among all relevant ZIF‐8 membranes. This strategy opens an avenue for precise interface engineering in membranes and the resultant high performance is appealing in the propylene separation industry.
