What is a nanocomposite material?
Nanocomposites are the heterogeneous/hybrid materials that are produced by the mixtures of polymers with inorganic solids (clays to oxides) at the nanometric scale. Their structures are found to be more complicated than that of microcomposites.
How do you make nanocomposite?
Various types of nanocomposite films have been prepared by the sol-gel process and used as active materials for gas sensors. 10. The preparation of a silica glass begins with an appropriate alkoxide which is mixed with water and a mutual solvent to form a solution.
What are advantages of nanocomposite packages?
The main advantages of nanocomposites over other composite materials are: high surface/volume ratio allows small filler size and distance between fillers; better mechanical properties- high ductility without strength loss, scratch resistance; improved optical properties (light transmission depends on particle size).
Why are nanocomposites better than composites?
Nanocomposites have a higher strength to weight ratio than carbon fiber or glass fiber reinforced composites. The tensile strength of carbon fiber is 6,300 MPa with a specific strength of 2,457 kN x m/kg while that of carbon nanotubes is 23,000 MPa and a specific strength of 45,268 kN x m/kg.
What are zero dimensional nanoparticles?
The most common representation of zero-dimensional nanomaterials are nanoparticles. One dimension that is outside the nanoscale. This leads to needle like-shaped nanomaterials. 1-D materials include nanotubes, nanorods, and nanowires.
What are the advantages and disadvantages of nanomaterials?
Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources and life-saving medical treatments. Potential disadvantages include economic disruption and possible threats to security, privacy, health and the environment.
Is nanotechnology being used today?
Nanotechnology is being used in developing countries to help treat disease and prevent health issues. Purification and environmental cleanup applications include the desalination of water, water filtration, wastewater treatment, groundwater treatment, and other nano-remediation.
What is so special about nanomaterials?
Nanomaterials are special for several reasons, but for one in particular – their size. Nanomaterials are up to 10 000 times smaller than the width of a human hair. And this tiny size makes them very valuable for all kinds of practical uses.
What are the impacts of nanotechnology to humans as to health?
The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems. Studies in humans show that breathing in diesel soot causes a general inflammatory response and alters the system that regulates the involuntary functions in the cardiovascular system, such as control of heart rate.
What are the impacts of nanotechnology to humans as to social interaction?
The societal impacts of new technologies are easy to identify but hard to measure or predict. Nanotechnology will have significant social impacts in the areas of military applications, intellectual property issues, as well as having an effect on labor and the balance between citizens and governments.
What is the importance of nanotechnology?
Why is nanotechnology important? Nanotechnology improves existing industrial processes, materials and applications by scaling them down to the nanoscale in order to ultimately fully exploit the unique quantum and surface phenomena that matter exhibits at the nanoscale.
How do we use nanotechnology in everyday life?
Everyday products that use nanotechnology
- Sunscreen. Nanoparticles have been added to sunscreens for years to make them more effective.
- Clothing.
- Furniture.
- Adhesives.
- Coatings for car paintwork.
- Tennis balls.
- Computers.
What are the negative impacts of nanotechnology?
Materials which by themselves are not very harmful could be toxic if they are inhaled in the form of nanoparticles. The effects of inhaled nanoparticles in the body may include lung inflammation and heart problems.
Do nanotechnology improve our society?
Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, homeland security, medicine, transportation, energy, food safety, and environmental science, among many others.
What are the negatives of nanotechnology?
Disadvantages include: Potential dangers to humans and the environment. Loss of manufacturing and agricultural jobs. Economic market crashes related to a potential lower value of oil due to more efficient energy sources and gold or diamonds, materials that can be reproduced with molecular manipulation.

What are the characteristics of nanotechnology?
Characteristics of Nanotechnology Nanotechnology deals with putting things together atom by atom and with structures so small they are invisible to the naked eye. It provides the ability to create materials, devices and systems with fundamentally new functions and properties.
What are the possible environmental risks of nanotechnology?
Soil microorganisms can be affected when, for example, sewage sludge contaminated with nanosilver is spread on fields. Nanosilver particles show negative effects on fishes and crustaceans already at low concentrations; in mammals, this material is toxic only at very high concentrations.
