Title: Energy-saving writing instrument

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an energy-saving writing instrument, more particularly to an energy-saving writing instrument having functions of being written thereon, and written texts and/or patterns can be widely wiped off and having advantages of thermal resistance, anti-dirt or waterproof. 
     2. Description of Related Art 
     Conventional objects for a purpose of writing are generally papers, and papers are made of pulp. But the pulp is obtained by cutting down green forests or plants, and papers, regardless newly-made or re-used, need large amount of energy and result in concerns of environmental protection. With less available resources in the earth and energy-saving and carbon reduction are emphasized, so how to let papers can be repeatedly used by writing with pens is an important issue for environmental protection and energy-saving and carbon reduction. 
     A conventional stick-on notepaper, e.g. the Post-it® notepaper made by 3M, is a paper with glue coated on a part of the backside thereof, so as to be stuck on a wall, tabletop, window or door panel, but texts and/or patterns written on said Post-it® notepaper can not be wiped off unless it is written by a pencil, so a reusable function is not completely provided; thus consumers may have to spend more money buying said notepaper and environmental protection and energy-saving issues are therefore occurred. With the energy-saving writing instrument having spot glues on its backside, disadvantages of conventional stick-on papers can be improved. 
     After texts and/or patterns are written on a piece of paper with pencils, an eraser can be used to erase in a small area, if a large area is desired to be erased, it may take longer time and the paper is more likely broken; or writing with a ball pen, a correction fluid or correction strip can be used to erase in a small area, if a large area is desired to be erased, it also may take longer time and result in more cost and the environmental protection issue is occurred. 
     Therefore developing a novel energy-saving writing instrument to improve the mentioned disadvantages is needed.

     As shown in figures, the energy-saving writing instrument provided by the present invention comprises: a thin film layer  10 ; and an interface modification member  20 . 
     The thin film layer  10  is a piece of paper or a plastic film, wherein the plastic film is, e.g. but not limited to, PET, PVC, Nylon, PI, TPU, PE, PP or Teflon. 
     The interface modification member  20  is applied on one surface of the thin film layer  10  with a laying means, e.g. but not limited to the upper surface, or is uniformly provided on the thin film layer  10 ; in this embodiment, the laying means for applying the interface modification member  20  on the thin film layer  10  is adopted as an illustration but not as a limitation for other feasible means. 
     The interface modification member  20  is, e.g. but not limited to, polymer containing silicon or fluorine, oligomer, an interfacial active agent containing silicon or fluorine or abrasion proof powder; wherein the abrasion proof powder is, e.g. but not limited to, silicon dioxide, calcium carbonate, metal powder or mica powder. 
     The interface modification member  20  is served to modify the surface of the energy-saving writing instrument of the present invention, thus the surface thereof is able to be written with a pencil, ball pen, water-based pen or oil-based pen, and the surface of the energy-saving writing instrument of the present invention is provided with functions of anti-dirt, anti-scratch and thermal resistance, so the energy-saving writing instrument can be adhered on a floor, door panel, tabletop, or wall for protecting the floor, door panel, tabletop or wall. The thin film layer  10  is further provided with additive having various colors (not shown) for satisfying consumers&#39; needs. 
     After the modification, the surface of the thin film layer  10 , regardless its material of paper or plastic, is able to be written with a pencil, ball pen, water-based pen or oil-based pen, and texts and/or patterns written thereon is able to be widely wiped off with paper or cloth, so the thin film layer  10  is provided with a rewritable function, for example being used as a piece of paper for calculation, therefore objects of rewritable and energy-saving and carbon reduction are achieved, and the paper is protected from being damaged and cost of using correction fluids or correction strips is reduced and environmental protection is also considered. 
     The energy-saving writing instrument provided by the present invention is further installed with a spot glue layer  30  on the other surface of the thin film layer  10 , e.g. but not limited to the lower surface, the spot glue layer  30  is installed with a plurality of spot glues  31  so as to be glued on a surface, e.g. but not limited to a tabletop, door panel, floor or wall, so that the tabletop, door panel, floor or wall is able to be written with different types of pens and be wiped off, and is also provided with functions of abrasion proof, thermal resistance and waterproof.
