A poly(acrylamide) sensor has been developed which uses the segmental mobility of another polymer poly(acrylic acid) with an attached fluorescent marker. The system uses interpolymer complexation, which leads to reduced segmental mobility.

Cellulose Adsorbent

The spherical cellulose adsorbent was prepared by grafting acrylic acid onto the spherical cellulose beads prepared by NMMO method. The effecting factors, e.g., monomer concentration, initiator concentration, reaction temperature and reaction time were optimized by the orthogonal and signal-factor experiments and the structure of the adsorbent was characterized by FTIR and SEM. The graft mechanism was also discussed. Moreover, the spherical cellulose adsorbents were shown to behave as good sorbents for basic amino acids L-Arg, L-Lys and L-His.

Poly Acrylic Acid

The adsorptions of polystyrene, poly(methoxystyrene), poly(acrylamide), and poly(acrylic acid) on aluminum oxide are investigated with inelastic electron tunneling spectroscopy. Comparison with infrared data for thin polymer films of the polymer samples gives insight into the adsorbed polymer configuration. Data indicate that poly(styrene) is weakly physisorbed to aluminum oxide, while poly(methoxystyrene), poly(acrylamide), and poly(acrylic acid) react to form strong bonds with the oxide surface. On the basis of this data, adsorption mechanisms are suggested for each of the polymers. Poly(acrylamide) adsorbs via a protonation of the amine group by the surface hydroxyl groups. Poly(4-methoxystyrene) forms a phenolate ion and can react further with the aluminum surface centers. Poly(acrylic acid) adsorbs to the oxide surface in a manner analogous to that of small organic acids such as the carboxylate ion.
