Eventually, the group produced a plastic composed of two polymers.
The new material, described online 25 April in Science by synthetic chemist Andreas Lendlein of mnemoScience GmbH in Aachen, Germany, and biomedical engineer Robert Langer of the Massachusetts Institute of Technology, is composed of two polymers, each already used separately in clinical applications such as drug delivery.
Here we report the development of a PEG-based interpenetrating network (IPN), which is composed of two polymer networks that can independently and simultaneously crosslink to form hydrogels in a cell-friendly manner.
By comparing this with the data obtained by small-angle X-ray scattering and differential scanning calorimetry, the experimental results are discussed in terms of dynamical heterogeneity of miscible polymer blends composed of two polymer components with a large difference in glass transition temperatures.
It is composed of two polymer fractions [ 2]: the moderately branched amylopectin, forming the semi-crystalline backbone of the starch granule [ 3, 4]; and amylose, a fraction with very few branches, which is embedded inside the amylopectin matrix.
In this work, we developed a wound healing cream composed of two different polymers, namely chitosan and gelatin with chlorhexidine along with calcium phosphate nanoparticles.
Starch is composed of two distinct polymers: amylopectin and amylose.
They are composed of two glucan polymers, the generally linear fraction, amylose, and the branched fraction, amylopectin.
This structure is stabilized by the cytoskeleton, which, similar to non-neuronal cells, is composed of two major polymers, the highly plastic filamentous-actin (F-actin) and the more stable microtubule (MT) networks.
Reserve starch is accumulated in the amyloplast organelles and is composed of two different glucosidic polymers, amylose and amylopectin.
Lignocellulosic biomass is composed of three main polymers: cellulose, hemicellulose, and lignin which are tightly linked and organized [ 1].
