Abstract

The introduction of conjugated building blocks can improve the adsorption performance of hyper-crosslinked polymers (HCPs). Pyrene was introduced into the HCPs using chloromethylated polystyrene as the precursor, facilitating the hyper-crosslinking through a Friedel–Crafts reaction to finally synthesize an efficient adsorbent named CaHe-2. 1-Naphthylamine and 1-naphthol could be rapidly removed by CaHe-2 within 20 min with high removal efficiencies of 93.8% and 90.6%. The maximum adsorption capacity of CaHe-2 reached 171.71 mg g⁻¹ for 1-naphthylamine, exceeding most of previously reported adsorbents in, and 184.86 mg g⁻¹ for 1-naphthol, which is the maximum value reported so far. The removal efficiencies of CaHe-2 still remained > 98% after five cycles. This conjugation enhancement resulted in drastic changes in the 1-naphthylamine and 1-naphthol adsorption property of porous polymers, displaying a new strategy for creating HCPs with high adsorption capacities.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
