Programmable release of a plant hormone, 1‐naphthylacetic acid (NAA), could be achieved by using a novel zeolite–hydrofilm (ZHF) composite. The ZHF was prepared using poly(vinyl alcohol) and glutaraldehyde as a cross‐linking agent with the addition of different amounts of zeolite A (0, 1.5, 2.0, 2.5...
