“…Therefore, we used hyperbranched polyesters (HBP) that were prepared by the same synthetic approach and having a similar branched aromatic ester structure and molar masses, but which had different end groups (B) that had been introduced during the synthesis by appropriate AB 2 monomers [7,8,9]. In a previous paper [10], we presented our first results concerning sensoric properties of layers prepared from these polymers showing the selective swelling in humid air.…”

Hyperbranched polyesters (HBP) with different end groups (P-OH, P-COOH, P-OAc) were prepared as thin films. Their surface properties were investigated using zeta potential and contact angle measurements. The differences in surface properties between P-OH and P-COOH, on the one hand, and P-OAc, on the other hand, predicted different behavior in sensoric applications. Therefore, the vapor of the homologous series of alcohols from methanol to pentanol was exposed to the thin films. Changes in thickness were observed with reflectometric interference spectroscopy (RIfS). First investigations in a current analytical problem for the detection and discrimination of refrigerants (freons) using P-OH as sensitive layer have been shown. Polydimethylsiloxane (PDMS) and poly(ether urethane) (PUT) were used as reference sensor materials for the RIfS measurements.

“…A highly branched poly(acrylic acid) film attached to a flat gold surface has been successfully applied to a number of technical applications including corrosion inhibition, chemical sensing, cellular engineering, and micrometer-scale patterning, due to an extremely high density of functional groups at the surface [107]. The surface chemistry and interfacial properties of hyperbranched polymers have also become fields of growing interest [2,[108][109][110][111][112][113][114][115]. Figure 14 summarizes hyperbranched, branched, and linear polymers grafted on surfaces.…”

This review summarizes recent advances in the synthesis and characterization of hyperbranched (meth)acrylates. We will focus on self-condensing vinyl (co)polymerization as an effective method for the synthesis of hyperbranched polymers. Molecular parameters of hyperbranched polymers obtained by self-condensing vinyl (co)polymerization are discussed from a theoretical point of view. Solution properties and melt properties of the resulting hyperbranched poly(meth)acrylates and poly(acrylic acid)s are reviewed. A novel synthetic concept for preparing hyperbranched polymer brushes on planar surfaces and nanoparticles is also described.
