Polydopamine particles for next-generation multifunctional biocomposites

Abstract

Polydopamine particles were used as fillers for constructing multifunctional composites for the first time.

Nanodiamond-mediated crystallization in fibers of PANI nanocomposites produced by template-free polymerization: Conductive and thermal properties of the fibrillar networks

“…9d). A rough estimation of the conductibility of a single PANI fiber gives s values as high as a few hundreds of S/m, that are well within the range measured in other similar experiments on pure PANI fibers [1,66,67]. Note that such a parameter represents the PANIeDND fiber conductibility along its long axis direction, since the experimental configuration used for the measurements does not allow the access to the direction normal to the main axis.…”

Hydroxide ion-mediated synthesis of monodisperse dopamine–melanin nanospheres

“…[1][2][3][22][23][24][25][26][27] However, the mechanism and kinetics of dopamine reaction remain unrevealed, providing only limited control over size of nanospheres. Furthermore, physical and chemical properties of dopamine-melanin spheres are not systematically investigated, despite their importance of the surface modification and applications.…”

“…[22,23] Dopamine rapidly reacting in a basic condition, forms the stable dispersion of dopaminemelanin nanospheres in water. [22][23][24] Dopamine based melanin synthesis has been developed in the goal of controlling the size of nanoparticles; various template materials such as peptides and surfactants are used to make well-defined dopamine-melanin nanoparticles. [25][26][27].…”

Host–guest interactions in poly(N-isopropylacrylamide) gel

“…The total mass loss is 77.2 %, leaving 22.8 % residue, very close to reference data [23]. The melting point is detected in the DTA response at 244.7 °C with a corresponding enthalpy of 193.7 J g -1 (36.8 kJ mol -1 ).…”
