  • Control in Coloration and Estimation of the Refractive Index by Porous Polymeric Membranes Prepared by the "Miniemulsion" Templating Method

    Fukui Y., Sumida H., Sugaya Y., Fujimoto K.

    ACS Applied Polymer Materials (ACS Applied Polymer Materials)  4 ( 10 ) 7547 - 7553 2022年10月

     概要を見る

    We fabricated porous polymeric membranes using the miniemulsion templating method to investigate the transmitted and scattered lights in terms of the Christiansen filter effect. This method made it possible to produce porous polymeric membranes with different refractive indices by polymerization of different monomers and copolymerization of monomers. When a membrane with an open-cellular structure was immersed in a liquid, the transmitted light was observed at a wavelength where the refractive indices of the polymeric phase and the liquid matched. Angle-independent color derived from the scattered light could also be observed. When the porous membrane of poly(2-ethylhexyl methacrylate) (EHMA) was immersed in a mixture of different kinds of liquids, the maximum wavelength of the transmission (λmax) changed according to the refractive index matching of the polymeric phase and the liquid, resulting in the change in coloration. Next, when the P(EHMA-co-EGDMA) membrane was immersed in a mixture of toluene and d-limonene, λmax and color varied depending on their mixing ratios. This coloration was controlled by temperature and the refractive indices of the polymeric phase and the liquid. Furthermore, we could estimate the refractive index of PEGDMA using λmax values obtained by immersing it into liquids with different refractive indices.

  • Functionalization of keratin nanoparticles by their internal modifications

     概要を見る

    We prepared keratin nanoparticles, which could respond to temperature and pH changes and to redox reactions, by electrostatic association of keratin and a cationic surfactant, dioctadecyl dimethyl ammonium chloride (DODAC). Solubilized keratin chains were assembled into nanoparticles (Ker-DODAC) and then crosslinked by disulfide formation. The resultant nanoparticles (Ker-DODACss) possessed a hydrophobic core composed of DODAC, enabling hydrophobic compounds to be loaed and retained in the core. By increasing the temperature, the fluidity of the core was increased, resulting in Ker-DODACss swelling and burst release of loaded compounds. Next, cholesterol was loaded into Ker-DODACss to modify the inner environment, such as the hydrophobicity and fluidity of the core. The nanoparticles (Ker-DODACss-Chol) exhibited reduced fluidity of the core and suppressed release of the payload. Furthermore, the release could be triggered by decreasing the electrostatic interaction between keratin and DODAC at pH values lower than 7.4. It was also found that Ker-DODACss-Chol possessed the ability to release payloads by breaking disulfide bonds. As a further internal modification, we incorporated a lipophilic antioxidant, α-tocopherol, into Ker-DODACss-Chol. It was confirmed that Ker-DODACss-Chol could act as a physical barrier to prevent α-tocopherol from undergoing oxidative degradation.

  • Preparation of a deformable nanocapsule by living radical polymerization in a liposome

     概要を見る

    We aimed to prepare an elastic nanocapsule by internal modification of a liposome with living radical polymerization. First, monomers and photoiniferters were encapsulated in liposomes. Then, UV light irradiation was used to conduct living radical polymerization in the liposomes. The obtained nanocapsules showed good absorption and retention of chemical substances depending on the binding ability to the incorporated polymers, and the absorption capacity could be controlled by the length and dissolved state of the polymer chains. In addition, dynamic morphological changes in the capsules were observed when liposomes with high membrane fluidity were employed. Morphological changes in the nanocapsules were induced by altering the pH value and ionic strength, resulting in the release of cargo in response to these environmental conditions.

  • Preparation of agarose xerogel nanoparticles by solvent evaporation from water nanodroplets

     概要を見る

    We developed a W/O miniemulsion reactor system enabling the preparation of biopolymer nanoparticles and control of their morphologies and inner microstructures. First, the W/O miniemulsion was prepared by suspending water nanodroplets containing agarose in oil. Then, we produced agarose hydrogel nanoparticles (AgarH) by the gelation of agarose in nanodroplets. Next, we prepared agarose xerogel nanoparticles (AgarX) by precisely tuning the water evaporation from AgarH. We controlled the morphologies (solid and hollow) and crystal structure of AgarX by changing the pressure and temperature during water evaporation. In fact, AgarX with a hollow structure was generated through rapid evaporation at a low pressure. AgarH was dissolved in Milli-Q water when the temperature was raised to 90 °C. On the other hand, AgarX remained a solid particle under the same conditions, likely because of its high crystallinity. We expect that this technique can be applied to prepare xerogels of diverse biomass-based polymers for the replacement of synthetic polymers.

  • Creation of porous polymeric membranes by accumulation of water nanodroplets in a miniemulsion system

    Fukui Y., Fujino R., Sugaya Y., Fujimoto K.

     概要を見る

    © 2020, The Society of Polymer Science, Japan. We developed a miniemulsion templating method to prepare porous polymeric membranes. First, water nanodroplets were suspended in an oil phase by using a nonionic and polymeric surfactant to form a water-in-oil (W/O) miniemulsion. After the nanodroplets accumulated by centrifugation, a small amount of monomer was added as an oil phase to resuspend the water nanodroplets in a monomer phase. Then, photopolymerization of the monomer phase was conducted to generate pores in the polymeric matrix. The size of the nanodroplets was tuned by the surfactant concentration to control the pore size of the membranes. We could produce pore morphologies such as closed-cellular, open-cellular, and bicontinuous structures by tuning the volume fraction of the nanodroplets. Alternatively, nanodroplets were accumulated by centrifugation, and then further surfactants were added to the monomer to suppress the coalescence of nanodroplets. This enabled us to generate a highly porous open-cellular structure while maintaining the size and spherical shape. Next, HAuCl4 was reduced by using the surfactant displayed at the inner surface of the pore wall as the reducing agent. Gold nanoparticles were produced in the inner pores of the polymeric membrane, showing coloration derived from local surface plasmon resonance.
