Characterization of PNIPAAm photografted on PET and PS surfaces

Preparation and characterization of thermo-responsive PDMS surfaces grafted with poly(N-isopropylacrylamide) by benzophenone-initiated photopolymerization

“…PNIPAAm has been reported to be immobilized onto substrates such as glass [2], silicon [3,4], gold [5,6], polystyrene (PS) [7][8][9][10], and polycarbonate [11] for chromatographic separation [12], protein adsorption and desorption [3,11], cell culture [7][8][9], etc.…”

Polymer Thermo-Responsive Gate Membranes

“…Liang et al [15] prepared temperature-sensitive membranes by photoinduced graft polymerization of NIPAAm monomer on the surface of PP (polypropylene) microfiltration membrane. Curti et al [16] graft polymerized NIPAAm monomers on previously oxidized PET (polyethylene terepthalate) and PS (polystyrene) surfaces. It is found that the grafted surface can show hydrophobic and hydrophilic character dependant of the temperature.…”

Detachment of human endothelial cell sheets from thermo-responsive poly(NiPAAm-co-DEGMA) carriers

“…Polymers with a thermally stimulated volume phase transition like poly(N-isopropylacrylamide) (PNiPAAm) [1] and NiPAAm containing copolymers can be prepared on solid surfaces by various techniques [2][3][4][5][6]. The resulting coatings respond with swelling and collapsing to small changes in the environmental temperature and can be used as cell culture carriers for harvesting cells and cell sheets without enzymatic or mechanical treatments [7][8][9][10].…”
