[RSC Advances] Polymer brushes functionalized Janus graphene oxide/chitosan hybrid membranes
A robust and simple method is reported to prepare polymer brushes functionalized Janus graphene oxide (GO)/chitosan hybrid membranes via the combination of interface self-assembly of GO and chitosan, with subsequent self-initiated photografting and photopolymerization (SIPGP) from both sides of GO/chitosan composite membranes.

A Supramolecular Janus Hyperbranched Polymer and Its Photoresponsive Self-Assembly of Vesicles with Narrow Size Distribution
Herein, we report a novel Janus particle and supramolecular block copolymer consisting of two chemically distinct hyperbranched polymers, which is coined as Janus hyperbranched polymer. It is constructed by the noncovalent coupling between a hydrophobic hyperbranched poly(3-ethyl-3-oxetanemethanol) with an apex of an azobenzene (AZO)
group and a hydrophilic hyperbranched polygl...

Facile method for large scale synthesis of magnetic inorganic/organic hybrid anisotropic Janus particles
Anisotropic Janus particles with strong magnetic iron oxide domain and polymer microsphere domain were prepared with large scale in one batch through a facile method via the solvothermal method in the presence of poly(methylenebisacrylmide-co-methacrylic acid) (P(MBA-co-MAA)) microspheres. The coordination interaction between the carboxyl acid groups and inorganic species played an essential role ...

92. Gyroid nanostructure through manipulation of unique molecular shape, polarity and functionalization of a Janus amphiphilic codendrimer
The gyroid structure with its interesting and mysterious symmetry has attracted the great attention of scientists with a variety of backgrounds. Constituting the gyroid structure through a precise control of the (macro)molecular architecture and the properties of its building blocks is a challenge. In this work we report our effort in creating a gyroid nanostructure in a Janus amphiphilic codendri...

72. Multiple H-Bonds Directed Self-Assembly of an Amphiphilic and Plate-Like Codendrimer with Janus Faces at Water-Air Interface
An amphiphilic diblock codendrimer composed of a third generation poly(methallyl dichloride) end-capped by eight hydroxyl groups (PMDC(OH)8) and a second generation poly(urethane amide) end-capped by four alkyl groups (PUA(C16)4) were found to self-assemble into highly oriented ribbons at the water−air interface. Further investigation on the ribbon formation shows that the ribbons are h...

中科院宁波材料所刘富研究员团队在Janus微孔正渗透膜领域取得研究进展
关键字：Janus，正渗透膜
正渗透作为一种渗透压驱动的膜分离技术，具有低能耗、低污染等优势，被广泛应用于海水淡化、水处理、压力阻尼渗透发电以及可控药物释放等领域。正渗透技术的核心在于正渗透膜以及汲取液的设计与合成。理想的正渗透膜应该具备高渗透性、高选择性、高的耐污染能力以及低的结构因子来降低浓差极化能力。
目前，正渗透膜材料主要有不对称醋酸纤维素膜和聚酰胺超薄复合膜（TFC），聚酰胺超薄复合膜主要由...

北京航空航天大学陈爱华课题组：光触发可逆自吞噬Janus纳米粒子的研究新进展
关键字：Janus，纳米粒子
具有光致异构性的偶氮苯可作为一种特殊的液晶基元。含有偶氮苯的嵌段共聚物在反式状态下可呈现液晶态，经紫外光照射后，偶氮苯转化为顺式结构，液晶态消失。通过可见光照，又可回复到液晶态。因此，偶氮苯嵌段共聚物的胶束聚集体可通过紫外光/可见光的交替照射来触发其可逆形变。但是，目前这类研究工作多为球形粒子或者囊泡，非球形聚合物粒子的可逆形变鲜见报道。此外，Janus（古罗马的“双面神”）粒子是一种在同...
