Abstract:
In this study, a hybrid composite containing melamine-based covalent organic polymer (MCOP) and ionic liquid (IL) was designed and employed for the functionalization of polymer monolith. The obtained polymer monolithic material was confirmed by scanning electron microscopy, Fourier-transformed infrared spectroscopy, X-ray photoelectron spectroscopy, and thermal gravimetric analysis. A polymer monolith microextraction (PMME) strategy was established based on the monolith for the enrichment of synthetic phenolic antioxidants, exhibiting high sensitivity, good stability and repeatability. Intra-day and inter-day relative standard deviations were both less than 10%. The developed PMME-HPLC method was applied to the preconcentration and determination of synthetic phenolic antioxidants in cosmetic samples and assessed through recovery studies. The developed polymer monolithic material had great potential as a candidate in the preconcentration field for PMME.

Polymer Classification: Crystallinity
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
