Broadband dielectric spectroscopy, one of the most powerful techniques to study the dynamics of molecular systems revealed not only different patterns of behavior of hyperbranched polymers of different architectures but also results in agreement with NMR on stereochemistry as a function of molecular architecture.
The fascinating architecture of hyperbranched polymer imparts a truck load of novel properties to the material.
A precursor polymer has been designed on the basis of an idea of conversion of hyperbranched polymer to an inorganic substance by lithographic procedure.
Novel supramolecular system of amphiphilic hyperbranched polymer with hyperbranched poly(β-cyclodextrin) core was designed and synthesized to accomplish a so-called selective encapsulation, where two types of guest molecules can be encapsulated into two types of molecular cavities from β-cyclodextrin (β-CD) and topography structure of hyperbranched polymer, respectively.
Dendrimers, a class of hyperbranched polymer explored in nanomedicine applications, were first described by Tomalia [1] and Newkome [2] separately as core-shell structures, built in a layer-by-layer way, forming generations.
In high concentrations of hyperbranched polymer, pH and DMSO significantly influence the emission of pyrene, and excimer peak disappears at 72% of DMSO fraction.
In addition, Dodiuk-Kenig et al. [ 48] studied the enhancement of electrospun nanofibers on the dental composites with the modification of hyperbranched polymer.
We have explored the use of nanoscale F-MRI agents capable of both chemotherapeutic delivery and F-MRI either in the form of hyperbranched polymer micelles or SCKs.
The effects of hyperbranched polymers (HBPs) on the cure behavior of tetrafunctional epoxy resin were investigated using differential scanning calorimetry (DSC) and FT-IR spectroscopy and compared with those of the linear analog.
Based on a brief description of the synthetic methodologies and properties of hyperbranched polymers, a detailed overview of the investigated phase behavior of branched polymer systems is given, followed by a discussion of new potential applications of hyperbranched polymers in the field of chemical engineering.
