Conducting Polymer Based Visual‐Aided Smart Thermosensors on Arbitrary Substrates

Conducting polymers have shown appealing performances as sensing materials in various smart sensors such as gas, chemical and biological sensors, owing to their unique physical and electrical properties. This study reports a novel development for the fabrication of visual‐aided smart thermal (VAST) sensors. The sensors are based on conducting polymers, temperature‐sensitive resin, and liquid crystal molecules via direct scrawling and in situ solventless polymerization. In the VAST sensor, the thermochromism resins and liquid crystals form a visual‐aided system with the real‐time early warning function and the conducting polymers provide an ultrahigh resolution by the measure of the change of resistivity. Additionally, these VAST sensors also hold the advantages of low cost, using simple tools, high stability, excellent adaptability to arbitrary substrates, wide application fields, and facile large‐scale fabrication. These properties are in favor of fabricating smart thermal sensors to satisfy the practical demands, such as the demonstrated temperature detecting system (especially flexible devices with nonplanar surface), thermodefect diagnostic system, smart battery monitoring system, and other environment monitoring.

Comparative study using different infrared zones of the solventless activation of organic reactions

In this work, the results of a study comparing the use of irradiation from different regions of the infrared spectrum for the promotion of several organic reactions, are presented and discussed. This use of eco-conditions provides a green approach to chemical synthesis. A set of ten different organic reactions were evaluated, including the Knoevenagel, Hantzsch, Biginelli and Meldrum reactions. It is important to highlight the use of a commercial device that produces infrared irradiation in the near infrared region and its distribution by convection providing heating uniformity, significantly reducing reaction times, achieving good yields and proceeding in the absence of solvent. It is also worth noting that a variety of different reactions may be performed at the same time. Finally, the products obtained were identified using TLC, together with corresponding MS-data, complementarily in comparison of NMR (1)H and (13)C data with literature information.

无溶剂不饱和环氧树脂-有机蒙脱土纳米复合材料制备及其性能研究

采用分子设计方法,将不饱和双键引入环氧树脂（EP）中,以苯乙烯为活性稀释剂制备了无溶剂型不饱和环氧树脂（UEP）,并对UEP-有机蒙脱土（OMMT）纳米复合材料的制备和性能进行了研究。用XRD测试了蒙脱土在被插层前后片层间距的变化,用SEM观察了复合材料冲击断面的结构。结果表明：蒙脱土（MMT）在EP固化过程中剥离成纳米级,复合材料断面为韧性断裂。     

Electrochemically Induced Addition Reactions in the Absence of Solvent and Supporting Electrolyte

Solvent‐ and supporting electrolyte‐free electrolysis in a two‐compartment cell proved to be effective for the direct electroactivation of C H acid‐containing compounds vs. catalytic addition processes. Michael adducts (including quaternary carbon centres) and 2‐nitroalkanols were obtained in very good yields and selectivity on application of a catalytic amount of electricity under galvanostatic conditions.     

硅酮防粘纸（剥离纸）加工技术的发展）续

3 防粘原纸(基材)——向高紧度高平滑度发展 3.1 防粘原纸的种类 硅酮防粘纸的涂布基材,有薄膜、预涂纸及特殊纸3大类。 多年来,预涂纸是硅酮防粘纸的主要涂布基材,用量也很大。用于自粘标签纸(不干胶纸)上,主要有3种：一种是普通的硫酸盐浆纸与聚乙烯用挤压复合的方法复合在一起的复合纸,常用于有机溶剂涂布工艺上;第二种是表面涂布一些成膜物质(如聚乙烯醇、醋丙共聚乳液、羧甲基纤维素、聚乙烯醇缩醛等)的涂布纸,对有机溶剂涂布及水乳涂布都适应;第三种是陶土涂布后经过超级压光的涂布纸,适合于水乳涂布工艺。美国喜欢用第三种,欧洲偏向于第二种,特别是用聚乙烯醇预涂,而在日本则大量使用第一种。用于压敏牛皮纸胶带上,则不管是哪个国家,大多使用聚乙烯复合纸作为基材。
