资料摘要
资料下载Intelligent polymers in response to an external stimulus such as pH, temperature, and ionic strength have received much attention because they not only can be used to construct new functional polymers but also can help us to understand some phenomena in life science.1 In comparison with biomacromolecules which function automatically, the conventional polymers exhibit discontinuous action since the response is usually driven y an on-off external stimulus. Recently, chemical oscillation as been used to fabricate polymeric materials with self-action.2–10 It has been reported that polymeric gels in a closed system driven y the Belousov-Zhabotinsky reaction exhibit self-oscillation.2–5 ue to the energy dissipation, the oscillation amplitude decays with time. pH-responsive gels with periodical volume changes riven by the Landolt reaction have also been prepared.6–8 Such els work in an open system with constant amplitude if the inputis continuous. Note that a responsive interface usually exhibits some unique properties in comparison with the bulk materials.However, the oscillating interface or surface has been seldomstudied.

TLS-100
简介：The TLS-100 is a portable thermal conductivity meter used to measure thermal conductivity and thermal resistivity. Perfect for testing the thermal conductivity of soil, polymers, viscous liquids, and other soft materials; as well as testing the thermal conductivity of concrete, rock, stone, or other hard materials. Tests can be performed with the push of a button. The collected data is automatically analyzed and results are displayed immediately.
THW--L2
简介：The Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896. The THW-L2 was designed with speed and operational simplicity in mind. With a single measurement of less than 2 seconds in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. The THW-L2 utilizes a non-stationary measurement approach and rapid test times to limit convective effects for samples with a wide range of viscosities.
HFM brochure
简介：The Heat Flow Meter (HFM) 100 is an easy-to-use rapid technique for the measurement of thermal resistance and thermal conductivity of insulation products, construction materials, packaging, and assemblies. Thermal conductivity is a measure of the ability of a material to conduct heat and can be critical for defining energy efficiency and thermal performance in materials. The Thermtest HFM has been designed and engineered to combine the highest accuracy, repeatability, widest temperature range, and industry leading performance, all at an exceptional value.
