Polymers

40.7K
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...

Layers of the Epidermis

The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

Thematic Layering in GIS

In the past, planning projects such as schools or public facilities required extensive manual effort to gather and compile data. Information such as property boundaries, soil characteristics, road networks, zoning regulations, and flood zones had to be sourced individually from courthouses, utility providers, and registry offices. Assembling these datasets into a coherent format often took several months, delaying project timelines.The introduction of Geographic Information Systems (GIS)...

Polymer Classification: Architecture01:14

Polymer Classification: Architecture

3.8K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Polymer Classification: Crystallinity

3.8K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Area of Science:

  • Materials Science
  • Organic Electronics
  • Photodetector Technology

Background:

  • Achieving high detectivity in all-polymer photodetectors (all-PPDs) requires thick photoactive layers to suppress dark current.
  • However, excessively thick layers reduce responsivity due to increased recombination losses.

Purpose of the Study:

  • To develop high-performance all-PPDs with optimized photoactive layer thickness.
  • To investigate the impact of novel polymer combinations on photodetector characteristics.

Main Methods:

  • Fabrication of all-PPDs using a narrowband-gap p-type polymer (NT40) and an n-type polymer (poly{[ N, N'-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]- alt-5,5'-(2,2'bithiophene)}).
  • Characterization of photodetector performance, including dark current density, responsivity, detectivity, and working frequency.

Main Results:

  • Achieved ultralow dark current density (4.85 × 10-10 A cm-2) with a 300 nm photoactive layer.
  • Obtained high detectivity (>1013 Jones) across a broad spectral range (360-850 nm).
  • Demonstrated high responsivity (0.33 A W-1 at 720 nm) and working frequency (>10 kHz).

Conclusions:

  • The developed all-PPDs exhibit excellent detectivity and responsivity, surpassing many existing devices.
  • High charge carrier mobility in the chosen polymers enables optimal photoactive layer thickness for superior performance.
  • These findings highlight the significant potential of these all-PPDs for practical applications.
