The graft copolymerization of acrylic acid (AA) onto commercial acrylic fibers (PAN) has been studied using Azobis(isobutyro)nitrile (AIBN) as an initiator. AA grafting initiated by radicals formed from thermal decomposition of AIBN. In this study, the effects of monomer and initiator concentration, time and temperature reaction on the grafting yield have been investigated.The optimum conditions for this grafting reaction were obtained with an AA concentration of 1.67 M, an AIBN concentration of 0.0097 M, a reaction temperature of T=85 C and with reaction time of 60 minutes.The fiber structure has been investigated by different experimental techniques of characterization such as Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), water absorption and also in this study has been investigated the mechanical property. The thermal analysis data showed that increasing in grafting yield, decreases the thermal stability of fiber. Grafting also affected slightly the fiber morphology. The experimental data of mechanical properties show clearly that by increasing of grafting yield, max extension will decrease. Grafting of poly AA improved water absorption.

“…However, these highly porous material suffer from a main limitation due to their limited surface area, which leads to a low binding capacity for the targeted species. However, this limitation can be overcome by polymer grafting to increase the binding capacity of the cryogels . Du and co‐workers .…”

A megaporous material harbouring a peptide ligand for affinity IgG purification

Common limitations of Protein A affinity chromatography include high adsorbent costs, ligand instability and possible ligand leakage. In this study, a short peptide with affinity for IgG was synthesized chemically and subsequently immobilized on a megaporous support. The support was prepared utilising the cryogel technique while the peptide-ligand was covalently immobilised via thiol-epoxy click chemistry. The cryogel support was chemically grafted to increase the number of reaction sites. This adsorbent was designated as "MP-Pep". Adsorption isotherms were employed to evaluate protein binding capacity. A maximum static binding capacity within the range of 30-60 mg/mL was observed for hIgG. This parameter compares well with other commercial and non-commercial adsorbents, as reported in the literature. As a control material, a Protein A grafted megaporous cryogel was synthesized. Dynamic binding capacity values were obtained by breakthrough analysis. The peptide cryogel showed a dynamic capacity value 9.0 mg/mL in comparison to 9.7 mg/mL in the case of the Protein A based adsorbent. The ratio of dynamic binding capacity to static binding capacity was 20%, indicating suboptimal product capture. However, the advantage of MP-Pep lies in its cost-effective preparations while maintaining a reasonable binding capacity for the targeted product. The presence of cooperative effects during protein binding could also represent an advantage during the processing of a feedstock containing a product in high concentration.
