Abstract
Currently, there is a great demand for functional materials with effective pathogen-killing properties. In this research, we describe the use of green technology “reactive extrusion” for the synthesis of potent antimicrobial materials based on Ethylene-vinyl alcohol copolymer (EVOH). Herein, the antimicrobial agent, copper (II) acetate was used without pretreatment and introduced into the EVOH matrices at high temperatures. The thermal reaction of copper (II) acetate within the EVOH matrices and their effect on the thermal and thermomechanical properties of the polymer were investigated in regards to their concentration. The physicochemical, thermal, and rheological features, as well as, metal salt release kinetics were reported. The antimicrobial agent had significant effects on the properties of the matrix. Results showed a reduction in the glass transition temperatures and storage modulus of the materials in response to the incorporation of copper (II) acetate. Finally, the antimicrobial activity of the products was studied and demonstrated a possibility to create antimicrobial materials in a one-step, solvent-free extrusion process.

Abstract
This paper deals with the synthesis of thermo-responsive microspheres with proteic structure exhibiting a transition temperature close to the body temperature. Temperature-sensitive hydrogels have attracted extensive interest due to their potential and promising applications in drug delivery field since they can undergo a rapid and reversible phase transition from a swollen to a shrunken state depending on environmental temperature. The hydrogels were synthesized by free-radical polymerization of hydrolyzed methacrylated gelatin (HGel-MA) and N,N'-methylenebisacrylamide as pro-hydrophilic multifunctional macromer and crosslinker, respectively, and N-isopropylacrylamide as thermo-responsive monomer. Thermal analyses showed negative thermo-responsive behavior for all compositions and, by increasing the content of the hydrophilic moieties in the network, the transition temperature raised to 36.9 degrees C, close to the physiological values. In order to test the materials as drug carriers, diclofenac sodium salt was chosen as model drug. Drug release profiles, in phosphate buffer solution (pH 7.0, 10(-3) M) at 25 and 40 degrees C, depend on the hydrogel's crosslinking degree and hydrophilic/hydrophobic balance in the polymeric network. For all formulations, in the shrunken state, the drug release percent values ranged from 80% to 100% after 24 h, and after 3 h, more than 60% of therapeutics was delivered. On the contrary, the swelling of the loaded microparticles produces, even after 30 h, a drug release percent of about 75%. By using semi-empirical equations, the release mechanism was extensively studied and the diffusional contribute was evaluated. The physico-chemical characteristics of thermo-responsive materials confirm the applicability of the microspheres as drug delivery device.
