“…The initial decomposition temperature of the PAN/CFP/ZnO-Bi 2 O 3 nanofibrous membrane was about 206 °C. The increase in the initial decomposition temperature was probably influenced by the interfacial effect between ZnO-Bi 2 O 3 and PAN polymers (increase in interfacial size and chemical stability with temperature [45,46] ). The above study revealed that the PAN/CFP/ZnO-Bi 2 O 3 nanofibrous membrane was very stable below 206 °C and showed excellent thermal stability.…”

With the widespread utilization of many radiation instruments, people are inadvertently suffering from radiation damage. But nowadays, there is still a lack of a lightweight, comfortable, and efficient wearable radiation‐proof multifunctional composite fibrous membranes in people's lives. To solve this problem, a green and efficient radiation‐resistant nanofibrous membrane consisting of cellulose fluorescent particles (CFP), ZnO‐Bi2O3 nanoparticles, and polyacrylonitrile (PAN) solution is prepared by an electrospinning technology. The microscopic characterization shows that the nanoparticles are uniformly dispersed on the surface of the nanofibrous membrane, forming a dense fibrous structure. The PAN/CFP/ZnO‐Bi2O3 nanofibrous membrane exhibits not only an excellent ultraviolet(UV) interception with an ultraviolet protection factor value of 337.99 ± 83.67, but also a strong shielding effect on low‐energy X‐rays. Simultaneously, it can not only photocatalytically degrade 88.17% of methylene blue solution within 150 min, but also remove 94.16 ± 0.96% of Escherichia coli and 99.07 ± 0.59% of Staphylococcus aureus within 3 h under dark incubation and kill all bacteria within 3 h under light. The adhesion, growth, and proliferation of bone marrow mesenchymal stem cells on the PAN/CFP/ZnO‐Bi2O3 nanofibrous membranes confirm its low cytotoxicity and good biosafety. Thus, it could be expected to be used in daily life products such as UV and X‐rays radiation protective clothing.

Interfacial Polymerization at the Alkane/Ionic Liquid Interface

et al. 2021

Polymerization at the liquid–liquid interface has attracted much attention for synthesizing ultrathin polymer films for molecular sieving. However, it remains a major challenge to conduct this process outside the alkane–water interface since it not only suffers water‐caused side reactions but also is limited to water‐soluble monomers. Here, we report the interfacial polymerization at the alkane/ionic liquid interface (IP@AILI) where the ionic liquid acts as the universal solvent for diversified amines to synthesize task‐specific polyamide nanofilms. We propose that IP@AILI occurs when acyl chloride diffuses from the alkane into the ionic liquid instead of being triggered by the diffusion of amines as in the conventional alkane–water system, which is demonstrated by thermodynamic partitioning and kinetic monitoring. The prepared polyamide nanofilms with precisely adjustable pore sizes display unprecedented permeability and selectivity in various separation processes.

Successive Redox‐Reaction‐Triggered Interface Radical Polymerization for Growing Hydrogel Coatings on Diverse Substrates

Growing lubricating hydrogel coatings in controllable manners on diverse material surfaces demonstrates promising applications. Here, a surface modification method is reported for in situ growing hydrogel coatings onto surfaces of diverse substrates in the absence of UV assistance. It is performed by decorating substrates with a universal mussel-inspired synthetic adhesive with catechol groups. Upon being immersed in reaction solution, these groups can assist substrate bonding and in situ capture and reduce Fe 3 + into Fe 2 + for decomposing S 2 O 8 2À into SO 4 À * catalytically at the interface to initiate interface polymerization of monomers. As a result, hydrogel coatings with controllable thickness could be grown on surfaces of arbitrary substrates to change their surface characteristics regardless of materials size, category, geometry and transparency, implying considerable potential in surface engineering.
