Through use of this water-/oil-repellent agent including a modified heterocyclic compound having a heterocycle and a C1-40 hydrocarbon group, adequate oil-resistance can be imparted to a substrate. The heterocycle is preferably a nitrogen-containing heterocycle. The hydrocarbon group is preferably an octyl group, a decyl group, an undecyl group, a lauryl group, a tridecyl group, a myristyl group, a palmityl group, a cetyl group, an isopalmityl group, a stearyl group, or a behenyl group. The heterocycle is preferably pyrimidine, pyridazine, pyridine, diazine, triazine, oxazole, or oxadiazole.

Highly porous nucleophilic organic cages (Nu-POC) were in-situ synthesized on cotton fibers by a condensation reaction between cyanuric chloride and melamine, and the products were employed as a robust wearable and flexible detoxifying protective material (denoted as POCotton) for vaporous pesticides. The covalent growth of Nu-POC particles on surfaces of cotton fibers retained the physical characteristics of Nu-POC to the greatest extend, which include specific surface area and porosity, while the cotton fabrics still remained wearable. The resultant POCotton can repeatedly adsorb fumigant vapors instantly (i.e., equilibrium reached within one minute) and massively (i.e., adsorption capacity at 596.88 mg/g of methyl iodide).

A zwitterionic resin is manufactured by a manufacturing method which includes the following steps. A first thermal process is performed on a first crosslinking agent and a choline having hydroxyl group or amino group to form a first mixture, in which the first crosslinking agent includes an isocyanate group. A second thermal process is performed on the first mixture, a second crosslinking agent, a chain extender, and an amino acid to form the zwitterionic resin, in which the chain extender includes a polyol.
