Preparation and properties of electron injecting molecular hybrid materials with high thermal performance
A series of oxadiazole-containing molecular hybrid materials with different structures (H1–H5) are controllably prepared by a hydrosilylation method based on the octahydridosilsesquioxane (POSS, T8H). All these resultant hybrid materials are soluble in common organic solvents, such as chloroform, toluene, tetrahydrofuran, and 1,2-dichloroethane, and possess good film-forming prop...

Engineering of fluorescent emission of silk fibroin composite materials by material assembly
This novel materials assembly technology endows the designated materials with additional/enhanced performance by fi xing “functional components” into the materials. Such functional components are molecularly recognized and accommodated by the designated materials. In this regard, two-photon fluorescence (TPF) organic molecules and CdTe quantum dots (QDs) are adopted as func...

149. Biomass Approach toward Robust, Sustainable, Multiple-Shape-Memory Materials
We report biomass-derived, shape-memory materials prepared via simple reactions, including “grafting from” ATRP and TAD click chemistry. Although the biomass, including plant oils and cellulose nanocrystals, has heterogeneous chemical structures in nature, these materials exhibit excellent multiple shape-memory properties toward temperature, water, and organic solvents, which are comparable to...

Design of Multistimuli-Responsive Shape-Memory Polymer Materials by Reactive Extrusion
Shape-memory polymers (SMPs) are a class of stimuli-responsive materials that have attracted tremendous attention in various applications, especially in the medical field. While most SMPs are thermally actuated, relating to a change of thermal transition (e.g., melting temperature), SMPs that can be actuated upon exposure to light are emerging. Recently, there has b...

EVALUATION OF DIFFERENT MEASUREMENTS FOR EFFECTIVE THERMAL CONDUCTIVITY OF FIBROUS MATERIALS
Effective thermal conductivity is generally recognized as the intrinsic factor to reveal the
thermal responses of fibrous materials. Here, two typical measurements, the step-wise
transient method and the guarded hot plate method, were utilized to identify their feasibility for the effective thermal conductivity of fibrous materials（no-woven fabric and twill fabric）with different stacking...

Study on water vapor diffusing coefficient of fibrous materials by fractal method
In this paper, a fractal model for predicting water vapor diffusion coefficient of hydrophobic fibrous materials is presented. To verify the validity of the model, the predicted results from the fractal model are compared with the experimental data and calculated values from the previous models. It is found that the fractal model predication shows better agreement with the experimental data than...

Measuring the thermophysical properties of porous fibrous materials with a new unsteady-state method
In this article, the authors first introduced a theoretical model dealing with unsteady-state heat conduction in porous fabric to assess the effects due to local convection during the testing. A few important issues are analyzed including the criterion for local thermal equilibrium in the fibrous materials and the confidence time region (t min–t max) during measuring process. The influence due to...

2016-Materials & Design: Preparation, mechanical and anti-friction performance of MXene/polymer composites
In this study, a Ti3C2 nanomaterial and Ti3C2/UHMWPE (ultrahigh molecularweight polyethylene) nanocomposites were prepared. The morphology, structure and properties of the Ti3C2/UHMWPE nanocomposites were investigated. The results indicate that Ti3C2 nanoparticle can improve the thermal and mechanical properties of UHMWPE. The crystallinity and hardness of the Ti3C2/UHMWPE nanocom...
