Functionalised titanate nanotubes (TiNTs) were incorporated to poly(5,5-bisbenzimidazole-2,2-diyl-1,3-phenylene) (PBI) or poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) for improving the interfacial compatibility between the polymer matrix and inorganic material and for altering the gas separation performance of the neat polymer membranes. Functionalisation consisted in oxidative polymerisation of dopamine-hydrochloride on the surface of non-functionalised TiNTs. Transmission electron microscopy (TEM) confirmed that a thin polydopamine (PDA) layer was created on the surface of TiNTs. 1.5, 3, 6, and 9 wt.% of PDA-functionalised TiNTs (PDA-TiNTs) were dispersed to each type of polymer matrix to create so-called mixed matrix membranes (MMMs). Infrared spectroscopy confirmed that –OH and –NH groups exist on the surface of PDA-TiNTs and that the nanotubes interact via H-bonding with PBI but not with PPO. The distribution of PDA-TiNTs in the MMMs was to some extent uniform as scanning electron microscope (SEM) studies showed. Beyond, PDA-TiNTs exhibit positive effect on gas transport properties, resulting in increased selectivities of MMMs. The addition of nanotubes caused a decrease in permeabilities but an increase in selectivities. It is shown that 9 wt.% of PDA-TiNTs in PBI gave a rise to CO2/N2 and CO2/CH4 selectivities of 112 and 63 %, respectively. In case of PPO-PDA-TiNT MMMs, CO2/N2 and CO2/CH4 selectivity increased about 25 and 17 %, respectively. Sorption measurement showed that the presence of PDA-TiNTs in PBI caused an increase in CO2 sorption, whereas the influence on other gases is less noticeable.

“…Han et al [27] have developed an adhesive and transferable free-standing film with dual function of osteoinductivity and antibacterial activity, which is obtained by sequentially assembling vancomycin immobilized oxidized sodium alginate and dexamethasone encapsulated chitosan-coated BSA nanoparticles on a poly-dopamine layer. Our previous reports also have demonstrated that surface modification of different materials via mussel-inspired chemistry and Michael addition reaction [28][29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Adsorption is an effective and commonly adopted method for removal of organic pollutants from environment. In this work, we described the synthesis and the adsorption behavior of poly(sodium p-styrenesulfonate hydrate) (PSPSH)-modified kaolin, which was obtained by combination of mussel-inspired chemistry and Michael addition reaction. The amino-terminated PSPSH was synthesized by free radical polymerization using cysteamine hydrochloride as the chain transfer agent and sodium p-styrenesulfonate hydrate as the monomer. Raw kaolin and PSPSH-modified kaolin were characterized using several techniques including transmission electron microscopy, Fourier transform infrared spectroscopy, thermal gravimetric analysis, and X-ray photoelectron spectroscopy in detail. The adsorption of methylene blue onto modified kaolin from aqueous solution was investigated, in which the effects of contact time, temperature, solution pH, and initial methylene blue concentration were studied. The experiment data were analyzed using two common adsorption models: Langmuir and Freundlich isotherm models. The kinetic adsorption data were analyzed using pseudo-first-order, pseudo-second-order, and intraparticle diffusion model. The values of thermodynamics constants such as entropy change (DS 0 ), enthalpy change (DH 0 ) and Gibbs free energy (DG 0 ) were also determined. The modified kaolin showed favorable dispersibility and convenient separation, high efficiency, and good regeneration capability in the removal of methylene blue from solution.Qiang Huang and Meiying Liu have contributed equally to this work.

“…It has been demonstrated that DA can be self-polymerized under alkaline solution to form polydopamine (PDA) films, which can be adhered to almost any solid surface without surface pretreatment [46][47][48][49][50][51][52][53][54][55]. For example, the surface modification of silica capillary with NH 2 -PEG was demonstrated by Wang et al Results showed that the novel coating could provide effective suppression of EOF and minimized adsorption of proteins.…”
