双壳微纳米相变胶囊/石膏复合材料等温吸放湿特性及机理研究

为了分析双壳微纳米相变胶囊复合材料的亲水性能,采用饱和盐溶液法对双壳微纳米相变胶囊复合材料的吸放湿平衡含湿量进行测试。并且采用红外光谱仪、扫描电镜对双壳微纳米相变胶囊、双壳微纳米相变胶囊复合材料结构及形貌进行测试。通过数学拟合方法,依据菲克定律以及吸放湿滞回环的表现,发现双壳微纳米相变胶囊复合材料存在着"绑定"水分,并提出了化学吸附不可逆吸放湿机理。结果表明,双壳微纳米相变胶囊外壳高分子壁材在复合材料吸放湿过程中,既有类似石膏孔隙的物理吸附,同时也存在"绑定"水分的化学吸附;"绑定"水分量随双壳微纳米相变胶囊掺量增加而增加,并且不随等温条件下相对湿度改变而变化。     

Hybrid Capsules via Self‐Assembly of Thermoresponsive and Interfacially Active Bionanoparticle–Polymer Conjugates

New bionanoparticles have been prepared from horse spleen ferritin by grafting thermoresponsive poly(N‐isopropyl acrylamide) (PNIPAAm) and photo‐crosslinkable 2‐(dimethyl maleinimido)‐N‐ethyl‐acrylamide (DMIAAm) from the protein surface. The 72 addressable amino groups on the exterior of HSF were modified with N‐hydroxysuccinimide‐activated 2‐bromo‐isobutyrate to form a macro‐initiator for atom transfer radical polymerization, which was performed in water/DMF solutions at low temperature. The modification of the HSF and the presence of the polymer shell were confirmed by size exclusion chromatography (SEC), sodium dodecyl sulfate‐polyacrylamide gel‐electrophoresis, transmission electron microscopy, and scanning force microscopy. The thermoresponsive behavior of the ferritin‐PNIPAAm conjugates was investigated in solution by UV–vis spectroscopy showing a phase transition in the form of a cloud point around 32 °C. Further, dynamic light scattering revealed an increasing hydrodynamic radius around this transition, indicating aggregation of the particles at elevated temperatures which was confirmed by transmission electron microscopy. Initial experiments show that the particles are highly surface active, much more than the individual components alone, which was demonstrated by pendant‐drop interfacial tension measurements. This leads to the fact that they form stable Pickering emulsions, i.e., emulsion droplets decorated with polymer‐modified bionanoparticles which can be cross‐linked successively. This allows the formation of capsules with thermoresponsiveness for controlled release purposes, e.g., in drug delivery.     

Study on Urban Construction History and Culture of the Tortoise City of Ganzhou

This paper states the geographic environment and brief history of Ganzhou City, specially discussing the idea of YANG Junsong, the Master of Feng Shui, who planned and built Ganzhou City in the shape of tortoise and its cultural connotation. It analyzes the advantages and disadvantages of its site selection, and discusses the urban flood and flood control. It also expounds the history of urban planning and construction. Ganzhou City is regarded as an example and a book of city planning and construction in ancient China in terms of the masters’ selection of the site and construction of the city, the city walls with functions of military defense and flood control, and the urban canal system of Fushougou against water-logging, the historical streets and lanes, the cultural relics, landscapes, etc., which not only make Ganzhou City the birthplace of first urban scenic spots and splendid historical culture, but also embodies the great wisdom of ancient Chinese. Three masters, YANG Junsong, KONG Zonghan, and LIU Yi, are heroes in the history of urban construction of Ganzhou.

Polyaniline–Silica Composite Conductive Capsules and Hollow Spheres

In this paper, we report on the preparation of monodisperse polyaniline (PANi)–silica composite capsules and hollow spheres on monodisperse core–gel‐shell template particles. An extension of the previously reported inward growth method was used. The samples were self‐stabilized without external additives. The core–gel‐shell particles were prepared by the inward sulfonation of monodisperse polystyrene particles. The introduced sulfonic acid and sulfone groups are responsible for the gel properties. The gel‐shell thickness and core size were synchronously controlled over the whole particle radius range. After aniline (ANi) monomer was preferentially absorbed in the sulfonated polystyrene shell, PANi was formed by polymerization. PANi was doped in situ with a sulfonic acid group to give the capsules a high conductivity. PANi hollow spheres were derived after the polystyrene cores were dissolved: their cavity size and shell thickness were synchronously controlled by using different core–gel‐shell particles. The PANi–silica composite capsules and hollow spheres were therefore prepared by a sol–gel process using tetraethylorthosilicate in the conducting shell. The PANi shell became more robust while maintaining the same conductivity level. Morphological results indicate that the PANi and silica formed a bicontinuous network. Fourier‐transform infrared (FTIR) spectra revealed that the hydrogen bonding in the PANi–gel shell was enhanced after the silica phase was incorporated, which could explain the high conductivity level after the silica phase was added. In a converse procedure, silica capsules and hollow spheres were prepared by a sol–gel process that incorporated tetraethylorthosilicate into the core–gel‐shell templates, which was followed by the absorption and polymerization of aniline in the silica shell thus forming PANi–silica composite capsules and hollow spheres. The silica capsules and hollow spheres thereby became conductive.
