J Hu, H Meng, G Li, SI Ibekwe - Smart Materials and Structures, 2012 - iopscience.iop.org

Stimuli-responsive polymers (SRPs) are smart materials which can show noticeable changes in their properties with environmental stimulus variations. Novel functionalities can be delivered to textiles by integrating smart SRPs into them. SRPs inclusive of thermal-responsive polymers, moisture-responsive polymers, thermal-responsive...

This paper investigates the thermomechanical behavior of a thermosetting shape memory polymer (SMP) by using a high temperature nanoindentation technique. The nanoindenter is equipped with a microheater and a sophisticated temperature control and monitoring system. This allows the SMP...

A photo-annealing approach for building functional polymer layers on paper.

Angewandte Chemie (International ed. in English)

Qian Q, Wang J, Yan F, Wang Y.
PMID: 24623708
Angew Chem Int Ed Engl. 2014 Apr 22;53(17):4465-8. doi: 10.1002/anie.201310714. Epub 2014 Mar 12.

A straightforward photo-annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near-infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo-annealing produces...

Reversible photorheological lyotropic liquid crystals.

Langmuir : the ACS journal of surfaces and colloids

Langmuir. 2014 Jan 28;30(3):866-72. doi: 10.1021/la4030469. Epub 2013 Sep 25.

We describe novel lyotropic liquid-crystalline (LLC) materials based on photoresponsive amphiphiles that exhibit rapid photoswitchable rheological properties of unprecedented magnitude between solidlike and liquidlike states. This was achieved through the synthesis of a novel azobenzene-containing surfactant (azo-surfactant) that actuates...

Cyclodextrin-based nanosponges as drug carriers.

Beilstein journal of organic chemistry

Trotta F, Zanetti M, Cavalli R.
PMID: 23243470
Beilstein J Org Chem. 2012;8:2091-9. doi: 10.3762/bjoc.8.235. Epub 2012 Nov 29.

Cyclodextrin-based nanosponges, which are proposed as a new nanosized delivery system, are innovative cross-linked cyclodextrin polymers nanostructured within a three-dimensional network. This type of cyclodextrin polymer can form porous insoluble nanoparticles with a crystalline or amorphous structure and spherical...

Electric field induced phase transitions in polymers: a novel mechanism for high speed energy storage.

Phys Rev Lett. 2012 Feb 24;108(8):087802. doi: 10.1103/PhysRevLett.108.087802. Epub 2012 Feb 23.

Using first-principles simulations, we identify the microscopic origin of the nonlinear dielectric response and high energy density of polyvinylidene-fluoride-based polymers as a cooperative transition path that connects nonpolar and polar phases of the system. This path explores a complex...

Photopatterned materials in bioanalytical microfluidic technology.

The rigid organic linkers N-(4-bromophenylsulfonyl)dithiocarbimate(2-) and N-(4-iodophenylsulfonyl)dithiocarbimate(2-) crystallize with two potassium cations and two water molecules in their asymmetric units, forming the title coordination polymers, [K(2)(C(7)H(4)BrNO(2)S(3))(H(2)O)(2)](n) and [K(2)(C(7)H(4)INO(2)S(3))(H(2)O)(2)](n). The anions and the water molecules link the potassium cations into...
