Encapsulation using hyperbranched polymers / Muhammad Irfan in Industrial & engineering chemistry research, Vol. 49 N° 3 (Fevrier 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 3 (Fevrier 2010) . - pp. 1169–1196 Titre : Encapsulation using hyperbranched polymers : from research and technologies to emerging applications Type de document : texte imprimé Auteurs : Muhammad Irfan, Auteur ; Matthias Seiler, Auteur Année de publication : 2010 Article en page(s) : pp. 1169–1196 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Encapsulation--Using  Hyperbranched--Polymers--Research--Technologies--Emerging  Applications Résumé : Dendritic macromolecules, such as hyperbranched polymers are increasingly being studied in the context of encapsulation. The intensive research on encapsulation using hyperbranched polymers is motivated by factors such as a cost-effective polymer synthesis and a customizable property profile. Hence, in the past few years, hyperbranched polymers have been employed as carriers for several guest molecules such as dyes, pharmaceuticals, cosmetics, catalysts, and aromatic hydrocarbons. However, hyperbranched polymers compete not only with perfectly structured dendrimers but also with conventional carrier molecules in terms of price and performance criteria such as processability, loading capacity, delivery efficiency and/or reduction of toxic side effects. This article aims at reviewing the research and development (R&D) in the field of encapsulation using hyperbranched polymers. Based on a summary of the most relevant R&D results and encapsulation technologies in this area, progress and challenges are discussed and new emerging applications are described. The most prominent emerging applications include the encapsulation and/or controlled release of (i) unstable or sensitive components (such as those used in the field of personal care), (ii) pharmaceutical substances (using hyperbranched carrier polymers with a narrow molar mass distribution), and (iii) inorganic nanoparticles to design versatile nanoreactors for catalytic applications.
