The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

Here, we describe protocols for the preparation of trans-cyclobutane fused cyclooctenes (tCBCO), their polymerization to prepare depolymerizable olefinic polymers, and the depolymerization of these polymers under mild conditions. Additionally, protocols for the preparation of depolymerizable networks and compression molding of rigid linear plastics based on this system are described.

The methodology to perform friction force microscopy experiments for contacting brushes is presented: Two polymer brushes that are grafted from (a) substrates and (b) colloidal probes are slid to show that, by using two contacting immiscible brush systems, friction in sliding contacts is reduced compared to miscible brush systems.
FAQs
Hydroxy fatty acids and glycerol form the connected polyester framework that gives the plant surface a continuous, cross-linked structure. This arrangement supports a hydrophobic barrier rather than a loose coating, helping aerial tissues restrict water movement and tolerate environmental stress. The polymer network therefore links molecular composition with the physical protection of the epidermal surface.
Soluble waxes strengthen the surface barrier by associating with the cutin framework or covering it. Their presence adds hydrophobic material at the plant exterior, further reducing permeability. Because the waxes and polymer matrix occupy related but distinct parts of the cuticle, researchers can consider both the underlying structure and surface-associated compounds when studying water retention and protection.
Hydrophobicity helps the cuticle limit uncontrolled movement of water across aerial tissues. At the same time, the layered cutin-wax arrangement moderates gas and water exchange instead of creating an undifferentiated surface. This balance matters biologically because plants need protection from water loss while maintaining regulated interactions between their tissues and the surrounding environment.
The cutin framework is a cross-linked polyester matrix built from hydroxy fatty acids and glycerol, whereas soluble waxes associate with or cover that matrix. This distinction separates structural support from surface-associated hydrophobic material. Studying the two components separately can clarify how the plant cuticle combines a persistent scaffold with compounds that reduce permeability at the outer surface.
Biologists examine cutin-wax polymers as part of research into how plants adapt to limited water and environmental stress. Their hydrophobic, cross-linked structure provides a relevant surface trait for understanding water retention in aerial tissues. This work can inform crop drought-tolerance research by connecting epidermal surface properties with the plant's ability to withstand dry conditions.
The cutin-wax surface is relevant to studies of pathogen penetration because its layered structure forms a physical limitation at the plant exterior. It also supports research on fruit storage, where surface permeability affects protection, and on biodegradable protective materials. These applications extend biological findings about plant surfaces into agricultural preservation and material-development contexts.
