The photoswitching behavior of the polyacrylic acid (PAA) doped by methyl orange (MO) brush film was investigated using spectral analysis UV-Vis absorbance, Fourier Transformation Infrared spectroscopy, 2D electrical conductivity mapping and Atomic Force Microscopy. kinetics time evolution photoisomerization PAA-MO PEBs from E-state to Z-state UV-light irradiation, reverse thermal relaxation ex...

Semi-synthetic hydrogels made of carboxymethyl hyaluronic acid (CMHA) and polyacrylic (PAA) were synthesized using electron beam irradiation. CMHA, with a degree substitution 0.87 molecular weight 149 kDa, was mixed linear PAA slightly crosslinked (Carbopol). The equal ratio the CMHA-Carbopol blends (10% 10% Carbopol) successfully crosslinked, even at low irradiation dose 20 kGy, producing hydr...
