Summary: The working environment for tubing in oil and gas fields is becoming more serious due to the exploration of unconventional oil and gas resources, leading to the increasing need for a protective internal coating to be used in tubing. A new mica-graphene/epoxy composite coating with different graphene contents (0.0, 0.2, 0.5, 0.7, and 1.0 wt.%) was prepared to improve the tubing resistance to a corrosive medium. The results showed that the addition of a certain amount of graphene into the mica/epoxy coating significantly improved the corrosion resistance of the composite coating, with the coating containing 0.7 wt.% graphene exhibiting the best performance.

Summary: In this study, polyacrylonitrile (PAN) modified with hexamethylene diamine (HMDA) and glutaraldehyde activation was utilized as a carrier for immobilizing Candida rugosa lipase. The immobilized lipase showed the highest activity at pH 8.0, with a yield of 81% and an activity of 91%. After recycling and storage, the immobilized lipase maintained a significant percentage of its initial activity. The results suggest that synthetically modified PAN is a suitable support for enzyme immobilization and has potential for commercial applications.

Summary: A UV curable hybrid material from palm oil was prepared with glycerol and glycidyl methacrylate (GMA), but it was brittle and flammable. Tri-n-butyl phosphate (TnBP) and polypropylene glycol 400 (PPG) were added as a flame retardant and plasticizer respectively. The properties of the cured films and coated wood were influenced by the content of PPG 400 and TnBP, and the best flame retardant properties were achieved with 15% PPG 400 and 5% TnBP.
