Plasticized Polyvinyl Chloride
Plasticized polyvinyl chloride (p-PVC)—widely present in modern and contemporary art collections as objects, clothing and footwear, furniture and upholstery, and housewares and toys—is known to deteriorate very rapidly in museum collections. The tendency of colorless p-PVC-based objects to yellowing-browning in combination with stickiness and cracking are the main issues of this important plastic material, which require the attention of conservation scientists in cooperation with conservators, engineers, curators, and art historians.

Cellulose-Based Polymers in Additive Manufacturing
The materials for additive manufacturing (AM) technology have grown substantially over the last few years to fulfill industrial needs. Despite that, the use of bio-based composites for improved mechanical properties and biodegradation is still not fully explored. This limits the universal expansion of AM-fabricated products due to the incompatibility of the products made from petroleum-derived resources. The development of naturally-derived polymers for AM materials is promising with the increasing number of studies in recent years owing to their biodegradation and biocompatibility. Cellulose is the most abundant biopolymer that possesses many favorable properties to be incorporated into AM materials, which have been continuously focused on in recent years. This critical review discusses the development of AM technologies and materials, cellulose-based polymers, cellulose-based three-dimensional (3D) printing filaments, liquid deposition modeling of cellulose, and four-dimensional (4D) printing of cellulose-based materials. Cellulose-based AM material applications and the limitations with future developments are also reviewed.

Polyurethanes in Biomedicine
Due to their mechanical properties, ranging from flexible to hard materials, polyurethanes (PUs) have been widely used in many industrial and biomedical applications. PU characteristics, along with their biocompatibility, make them successful biomaterials in short and medium time applications.  The most important biomedical applications of PUs include antibacterial surfaces and catheters, blood oxygenators, dialysis devices, stents, cardiac valves, vascular prostheses, bioadhesives/surgical dressings/pressure sensitive adhesives, drug delivery systems, tissue engineering scaffolds and electrospinning, nerve generation, pacemaker lead insulation and coatings for breast implants. The diversity of polyurethane properties due to the ease of bulk and surface modification plays a vital role in their applications.

Conducting Poly(Methyl Methacrylate) (PMMA)
Poly(methyl methacrylate), PMMA is a lightweight insulating material that is known for its high Young's Modulus and good optical transmittance properties. Benefiting from these properties, there are recently vast interests to produce conducting PMMA for various applications including electronics, corrosion protective coatings,  diodes, sensors, and many more. Conducting PMMA is possible to produce by incorporating conducting polymers such as  polyaniline (PANi) by physical blending method or by co-polymerization technique. PANi has been the main choice to incorporate with PMMA due to its good conductivity, better environmental stability, and good redox reversibility. In addition, the limitations of PANi include poor adhesion, low mechanical stability and, limited solubility in most organic solvents can be surpassed by blending or co-polymerizing with thermoplastics such as PMMA.
