Biodegradable Polyurethane Pressure-Sensitive Adhesives Using Biobased Polyols with Distinct Intrinsic Properties
Polyurethane pressure-sensitive adhesives (PSAs) were synthesized by reacting isophorone diisocyanate (IPDI) with mixtures of different biobased polyols, where polylactide diol (PLA 1000) acted as a hard polyol and cashew nut shell liquid (CNSL)-derived diol and castor oil (CO) acted as soft segments. Besides, CO played another role in the synthesis of the polyurethanes as a cross-linker to enhance the cohesion of the prepared PSAs. The effects of different ratios of polyols and NCO/OH on microphase separation, thermal, rheological, and adhesive properties of the polyurethane were comprehensively studied. A balanced PSA with excellent tack and sufficient peel strength was prepared by adjusting the ratio of different polyols at PLA1000/CNSL diol/CO = 4:4:2 and a suitable NCO/OH value of 0.70. Eventually, the biodegradability of PSA 442-0.70 was investigated, and the biodegradation rate reached 64.47% within 8 weeks, making it a promising environmentally friendly adhesive tape for packaging applications.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
