Permanent superhydrophilic surface modification in microporous polydimethylsiloxane sponge for multi-functional applications

Migration Crystallization Device Based on Biomass Photothermal Materials for Efficient Salt-Rejection Solar Steam Generation

“…After carbonization, biomass materials form amorphous carbon, which need to be soaked for a long time to show hydrophilicity. In order to make CGA soak quickly in water, combined with the previous study of the surface superhydrophilic method, benzophenone was used as a photoinitiator and UV-grafting of acrylic acid monomer on the surface of CGA was carried out (Figure h). − Compared with CGA, UV-grafting with PAA did not bring noticeable change in the weight, size, or pores of SH-CGA. Both the SEM micrographs of CGA and SH-CGA show an interconnected 3D framework of microporous structure with pore sizes varying from 5 to 50 μm, but there is a layer of coating on the surface of SH-CGA (Figure i).…”

Separation of distinct exosome subpopulations: isolation and characterization approaches and their associated challenges

“…52,53 PDMS is a preferred material for fabricating flexible microfluidic devices due to its unique rheological properties. 54 Additionally, novel surface modification strategies for PDMS enable changes from hydrophobic to hydrophilic state 55 to transform surface wettability and remove limitations on fluid flow.…”

One-step zwitterionization and quaternization of thick PDMAEMA layer grafted through subsurface-initiated ATRP for robust antibiofouling and antibacterial coating on PDMS

“…However, hydrophobic PDMS faces the serious problem of biofouling from non-specific protein adsorption, bacterial adhesion and subsequent biofilm development, which causes many undesirable infections and reduces the lifetime of biomedical devices, sometimes even leads to patient deaths [2,[5][6][7]. To solve this problem, PDMS is usually imparted with antibacterial function by tethering polymers on its surface [8][9][10][11][12]. Generally, these polymers can be divided into two categories according to their operating mechanism.…”
